   (1)  The station owner bears the burden of proving that the station owner provided proper supervision of the employee who committed the violation, but that the owner’s supervision could not have prevented the violation.

   (2)  By accepting the assessment of points the station owner waives the right to appeal the Department’s determination in the case to a court of record. If the station owner refuses to accept the point assessment, the Department will issue the suspension provided in this chapter for the offense committed.

 (c)  Point determination. When offering a point assessment, in lieu of a suspension, the Department will calculate points in the following manner:

   (1)  One point will be assessed for every month of suspension which the Department would otherwise impose.

   (2)  A point assessment will not exceed 8 points for a single violation.

   (3)  If an inspection station is currently serving a suspension for a violation of this chapter, no point assessment will be made.

 (d)  Point suspension. The Department will suspend the privileges of an official inspection station for an accumulation of points whenever the station accumulates 10 or more points.

   (1)  The first occurrence of an accumulation of 10 points or more shall result in a suspension for 2 months for each point over 9 points; the second occurrence of an accumulation of 10 points or more shall result in a suspension for 4 months for each point over 9 points; the third occurrence of an accumulation of 10 points or more shall result in a suspension for 6 months for each point over 9 points.

   (2)  The fourth occurrence for an accumulation of 10 or more points shall result in a permanent suspension.

   (3)  Only suspensions issued as the result of an accumulation of points shall be counted in determining whether a suspension for point accumulation’s is a second, third or fourth suspension.

   (4)  If the point record of a station has been reduced to zero, a subsequent accumulation of points that will result in the suspension of the station will be considered first, second, third and fourth suspensions.

 (e)  Voluntary discontinuance. A certificate of appointment will be cancelled by the Department whenever the owner voluntarily discontinues the operation of an emission inspection station. Remaining emission inspection materials shall be returned to the quality assurance officer upon request of the Department.

 (f)  Abandonment. A certificate of appointment will be cancelled by the Department, and inspection materials confiscated when the owner of record abandons the place of business and cannot be located.

 (g)  Sale of business. If an emission inspection station is sold or leased to a new owner, an application will not be considered while the station is suspended or restored pending an appeal of a suspension.

 (b)  ASM Test Score Calculation

   (1)  Exhaust gas measurement calculation.

     (i)   System response time

 The analysis and recording of exhaust gas concentrations shall begin 12 seconds after the applicable test mode begins, or sooner if the system response time is less than 12 seconds. The analyzing and recording of exhaust gas concentrations shall not begin sooner than the time period equivalent to the response time of the slowest transducer.

     (ii)   Sample rate

 Exhaust gas concentrations shall be analyzed at a minimum rate of once per second.

     (iii)   Emission measurement calculations.

 Partial stream (concentration) emissions shall be calculated based on a running 10-second average. The values used for HC(J), CO(J), and NO(J) are the raw (uncorrected) tailpipe concentrations.

Web Only Graphic

 (c)  

     (iv)   Dilution correction factor.

 The analyzer software shall multiply the raw emissions values by the dilution correction factor (DCF) during any valid ASM emissions test. The DCF accounts for exhaust sample dilution (either intentional or unintentional) during an emissions test. The analyzer software shall calculate the DCF using the following procedure, and shall select the appropriate vehicle fuel formula. If the calculated DCF exceeds 3.0 then a default value of 3.0 shall be used.

 (a)

Web Only Graphic

 Where [CO2]MEASURED and [CO]MEASURED are the instantaneous ASM emissions test readings.

 (b)  Calculate [CO2]adjusted using the following formulas.

   (1)  For gasoline:

Web Only Graphic

 (c)  RA = Relative humidity of the ambient air percent.

 (d)  PD = Saturated vapor pressure, MM HG at the ambient dry bulb temperature. If the temperature is above 86°F, then it shall be used in lieu of the higher temperature, until EPA supplies final correction factors.

 (e)  PB = Barometric pressure, MM HG.

   (2)  Pass/fail determination.

 A pass or fail determination shall be made for each applicable test mode based on a comparison of the applicable short test standards and the measured value for HC, CO, and NO as described in Paragraph (b)(1)(iii) of this section. A vehicle shall pass the test mode if the emission values for HC, CO, and NO are simultaneously below or equal to the applicable short test standards for all three pollutants. A vehicle shall fail the test mode if the values for HC, CO, or NO, or any combination of the three, are above the applicable standards at the expiration of the test time.

   §  2. ASM short test procedure.

 (a)  General requirements

   (1)  Vehicle characterization.

     (i)   Vehicle type: LDGV, LDGT1, LDGT2, HDGT, and others as needed;

     (ii)   Chassis model year;

     (iii)   Make;

     (iv)   Model;

     (v)   Number of cylinders;

     (vi)   Cubic inch or liters displacement of the engine;

     (vii)   Transmission type; and

     (viii)   Equivalent test weight.

   (2)  Ambient conditions.

 The ambient temperature, relative humidity and barometric pressure shall be recorded continuously during the test cycle or as a single set of readings up to 4 minutes before the start of the driving cycle.

   (3)  Restart.

 If shut off, the vehicle shall be restarted as soon as possible before the test and shall be running at least 30 seconds prior to the start of the ASM driving cycle.

   (4)  Void test conditions.

 

   The test shall immediately end and any exhaust gas measurements shall be voided if the instantaneous measured concentration of CO plus CO2 falls below 6% or the vehicle’s engine stalls at any time during the test sequence.

   (5)  Test time limit.

 The test shall be aborted or terminated upon reaching the overall maximum test time.

 (b)  Pre-inspection and preparation.

   (1)  Accessories.

 All accessories (air conditioning, heat, defogger, radio, automatic traction control if switchable, and the like) shall be turned off (if necessary, by the inspector).

   (2)  Exhaust leaks.

 The vehicle shall be inspected for exhaust leaks by test personnel. Audio assessment while blocking exhaust flow shall be acceptable. Vehicles with leaking exhaust systems shall be rejected from testing.

   (3)  Fluid leaks.

 Vehicles with excessive leaking engine oil, transmission fluid or coolant shall be rejected from testing.

   (4)  Mechanical condition.

 Vehicles with obvious mechanical problems (engine, transmission, brakes or exhaust) that either create a safety hazard or could bias test results shall be rejected from testing.

   (5)  Operating temperature.

 The vehicle shall be at proper operating temperature prior to the start of the test. The vehicle temperature gauge, if equipped and operating, shall be checked to assess temperature. Vehicles in overheated condition shall be rejected from testing.

   (6)  Tire condition.

 Vehicles shall be rejected from testing if tread indicators, tire cords, bubbles, cuts or other damage are visible. Vehicles shall be rejected from testing if they have space-saver spare tires or if they do not have reasonably sized tires on the drive axle or axles. Vehicles may be rejected if they have different sized tires on the drive axle or axles. In test-and-repair facilities, drive wheel tires shall be checked with a gauge for adequate tire pressure. In test-only facilities, drive wheel tires shall be visually checked for adequate pressure level. Drive wheel tires that appear low shall be inflated to approximately 30 PSI, or to tire side wall pressure, or vehicle manufacturer’s recommendation. Alternatively, vehicles with apparent low tire pressure may be rejected from testing.

   (7)  Emission sample system purge/hang-up.

 While a lane is in operation, the sample system shall be continuously purged after each test for at least 15 minutes if not taking measurements. If the HC reading, when the probe is sampling ambient air, exceeds 7 PPM C6 on an instantaneous measure, testing shall be prohibited. Testing may proceed after a determination is made that hang-up is less than 7 PPM C6 (that is, by eliminating the ambient background contribution to the measurement).

   (8)  Roll rotation.

 The vehicle shall be maneuvered onto the dynamometer with the drive wheels positioned on the dynamometer rolls, prior to restraining the vehicle and test initiation. The rolls shall be rotated until the vehicle laterally stabilizes on the dynamometer. Vehicles that cannot be stabilized on the dynamometer shall be rejected from testing. Drive wheel tires shall be dried if necessary to prevent slippage.

   (9)  Cooling system.

 When ambient temperatures exceed 72°F, testing shall not begin until the cooling system is positioned and activated. The cooling system blower shall be positioned to direct air to the vehicle cooling system, but shall not be directed at the catalytic converter.

   (10)  Vehicle restraint.

 Testing shall not begin until the vehicle is restrained. Any restraint system shall meet the requirements of §  3(a)(5)(ii). In addition, the parking brake shall be set for front wheel drive vehicles prior to the start of the test, unless parking brake functions on front axle or if it is automatically disengaged when in gear.

   (11)  Dynamometer warm-up.

 The dynamometer shall be in a warmed-up condition prior to official testing and use shall be locked out until it is warmed up. Dynamometers resting (not operated for at least 30 seconds and at least 15 mph) for more than 30 minutes shall pass the coast-down check specified in §  4(b)(1) prior to use in testing. Control charts may be used to demonstrate the need for less frequent warm- up.

 Testing cannot occur below 41°F.

   (12)  Analyzer warm-up.

 An emissions test shall not begin before the analyzer has been adequately warmed up. Turning on the analyzer for a time period of at least 4 times the period of time required to reach stability as demonstrated in the equipment certification (see §  7) shall constitute ‘‘warmed-up.’’

 (c)  Test sequence.

   (1)  The test sequence shall consist of a single ASM mode described in §  2(d) of this subpart. Vehicles that fail the first chance test as described in §  2(d) of this subpart shall receive a second chance test under §  2(e) of this subpart. The second chance test shall consist of a repetition of the mode or modes that were failed in the first chance test according to the conditions in §  2(e) of this subpart.

   (2)  The test sequence shall begin only after the following requirements are met:

     (i)   Load setting.

 Prior to each mode, the system shall automatically select the load setting of the dynamometer from a supplied look-up table.

     (ii)   Accessories.

 The vehicle shall be tested in as-received condition with all accessories turned off. The engine shall be at normal operating temperature.

     (iii)   Gear selection.

 The vehicle shall be operated during each mode of the test with the gear selector in drive for automatic transmissions and in second (or third if more appropriate) for manual transmissions for the loaded modes. Engine RPM shall be measured per §  3(d)(6).

     (iv)   Sample probe.

 The sample probe shall be inserted into the vehicle’s tailpipe to a minimum depth of 10 inches. If the vehicle’s exhaust system prevents insertion to this depth, a tailpipe extension shall be used.

     (v)   Multiple exhaust pipes.

 Exhaust gas concentrations from vehicle engines equipped with functionally independent multiple exhaust pipes shall be sampled simultaneously.

     (vi)   Automatic gas zero.

 The analyzer shall conduct an automatic zero adjustment using the zero gas specified in §  4(d)(iii).

     (vii)   Automatic zero adjustment.

 The zero adjustment shall include HC, CO, CO2 and NO channels.

     (viii)   Ambient air and HC hang-up determination.

 The analyzer shall perform the automatic zeroing, O2 calibration (if included) and ambient air reading, followed by an HC hang-up check. This process shall begin after initiation of data entry into the analyzer computer. The analyzer shall be locked out from testing until: (1) the ambient air (sampled through the probe) has less than 15 PPM HC and (2) the residual HC in the sampling system (probe sample—port sample) is less than 7 PPM.

     (ix)   Engine speed.

 For 1996 and newer vehicles equipped with Federal OBD systems or California OBD II systems, engine speed in RPM may be monitored by the standardized plug throughout the test. RPM readings shall be recorded on a second-by-second basis. In test-and-repair stations, engine speed shall also be monitored on all pre-1996 vehicles and recorded in the test record. For vehicles that are not equipped for OBD measurement, an alternative means of measuring engine speed (RPM) shall be provided.

 (d)  Overall test procedure.

 The test timer shall start (TT=0) when the conditions specified in paragraph (c)(2) are met. The dynamometer rolls reach 1.0 MPH due to the test vehicle’s initial acceleration for testing purposes, and the mode timer initiates as specified in paragraph (d)(2). The test sequence shall have an overall maximum test time of 290 seconds (TT-290). The test shall be immediately terminated or aborted upon reaching the overall maximum test time. The test mode in §  2(d)(3) may precede the test mode in §  2(d)(2).

   (1)  Preconditioning cycle.

 Vehicle preconditioning shall be performed prior to start of an official test. The preconditioning cycle must be approved by the Department. A state may waive the preconditioning requirement if it ensures that all vehicles are adequately warmed up prior to taking the final emissions measurements as described at §  1(b)(iii). The following preconditioning cycle is approved:

     (i)   The preconditioning timer shall start once the dynamometer has reached a speed of 15 or 25 mph (PT=0), consistent with the speed of the first test mode. The vehicle will continue to be operated for a maximum of 30 seconds at this speed within ±5 MPH and within ±10% of the wheel force tolerance specified in §  2(d)(2). The duration of the preconditioning cycle may be adjusted if a Department determines through the use of statistical process control methods that an alternative preconditioning cycle duration is adequate to ensure that vehicles are fully warmed up prior to testing. If the speed or wheel force fall above or below the tolerance, the preconditioning timer will reset to zero. Preconditioning time shall not be included in the overall maximum test time.

   (2)  ASM5015 mode.

     (i)   Mode timer.

 The mode timer shall start (MT=0) when the dynamometer speed (and corresponding wheel force) are maintained within 15±1.0 miles per hour for 5 continuous seconds. If the inertia simulation exceeds the tolerance specified in §  3(a)(4)(ii)(b) for more than 5 consecutive seconds after the mode timer is started, the test mode timer shall be set to TT=0. If this happens a second time, the test shall be aborted. The dynamometer shall apply the correct wheel force based on the required ASM horsepower load at 15 mph across the testing speed window (15±1.0 miles per hour) (that is, constant load over the speed range). The wheel force torque tolerance shall be ±5% of the correct wheel force at 15 MPH.

     (ii)   Look-up table.

 The dynamometer power shall be automatically selected from an EPA-supplied or EPA-approved look-up table, based upon the vehicle identification information described in §  2(a)(1). Vehicles not listed in the look-up table and for which ETW is not available shall be tested using the following default settings:

Full vans10.814.418.220.221.1

 If the dynamometer speed or wheel force falls outside the speed or wheel force tolerance for more than 2 consecutive seconds, or for more than 5 seconds total, the mode timer shall reset to zero and resume timing. The minimum mode length shall be determined as described in paragraph (d)(2)(iii). The maximum mode length shall be equal to 90 seconds elapsed time (MT = 90).

 If the speed at the end of the 10 second period is more than 0.5 mph less (absolute drop, not cumulative) than the speed at the start of the 10 second period, testing shall continue until the speed stabilizes enough to meet this criterion.

     (iii)   Pass/fail determination.

 The pass/fail analysis shall begin after an elapsed time of 22 seconds (MT = 22. A pass or fail determination shall be made for the vehicle and the mode shall be terminated as follows:

 (a)  The vehicle shall pass the ASM5015 mode and the mode shall be immediately terminated if, at any point between an elapsed time of 22 seconds (MT = 22) and 90 seconds (MT = 90), the 10 second running average measured values for each pollutant are simultaneously less than or equal to the applicable test standards described in paragraph (a).

 (b)  The vehicle shall fail the ASM5015 mode and the mode shall be terminated if paragraph (d)(2)(iii)(a) is not satisfied by an elapsed time of 90 seconds (MT = 90).

     (iv)   If ASM5015 is the first test mode, upon termination of the ASM5015 mode, the vehicle shall immediately begin accelerating to the speed required for the ASM2525 mode, if applicable. The dynamometer shall smoothly transition during the acceleration period and shall automatically reset to the load required for the ASM 2525 mode, if applicable, once the roll speed is achieved.

 (e)  Second chance tests.

 

   If a vehicle fails the 5015 test mode and completes all required test modes with emissions values for HC, CO and NO not greater than 150% of the applicable standard, the vehicle shall receive a second chance test for each failed test mode.

   (1)  If the vehicle fails the first-chance test, the test timer shall reset to zero (TT=0) and a second-chance test shall be performed, except as noted below. The second-chance test shall have an overall maximum test time of 110 seconds (TT=110) if one mode is repeated.

 NOTE: Maximum mode time:  90 sec.
+Maximum transition: 15 sec.
+DYNE stabilization:   5 sec.
           110 sec.

 12 sec. transport and 10 sec. averaging are included in the mode time as in the initial test.

   (2)  Repetition of failed modes for single mode ASM tests.

     (i)   If the vehicle is failing at the end of the mode, then the test mode shall not end at 90 seconds but shall continue for up to 180 seconds.

   §  3. ASM short test equipment.

 (a)  Dynamometer specifications.

   (1)  General requirements

     (i)   Capacity

 The dynamometer structure (for example, bearings, rollers, pit plates, and the like) shall accommodate all light-duty vehicles and light-duty trucks up to 9,000 pounds GVWR.

     (ii)   ASM load

 Dynamometer ASM load horsepower (HP5015YY) shall be automatically selected based on the vehicle parameters in the test record.

     (iii)   Alternative design

 Alternative dynamometer specification or designs may be allowed upon a determination by the Department that, for the purpose of properly conducting an approved short test, the evidence supporting these deviations will not cause improper vehicle loading.

   (2)  Power absorption.

     (i)   Vehicle loading.

 The vehicle loading used during the ASM driving cycles shall follow the equation in paragraph (a)(2)(ii) of this section at 15. Unless otherwise noted, any horsepower displayed during testing shall be HP5015YY.

     (ii)   HP calculation

 IHPXXXXYY = THPXXXX-PLHPZZ-YY -GTRL@ZZ MPH-YY- HPXXXXYY = IHPXXXXYY + PLHPZZ-YY

     (iii)   Range of power absorber.

 The range of the power absorber shall be sufficient to test all light-duty vehicles and light-duty trucks up to 9,000 pounds GVWR, using both the ASM5015 and ASM2525. The absorption shall be adjustable in 0.1 hp increments at both 15 mph and 25 mph.

     (iv)   Parasitic losses.

 The parasitic losses (PLHP) in each dynamometer system (such as windage, bearing friction and system drive friction) shall be characterized at 25 and 15 mph upon initial acceptance, and during each dynamometer calibration if required.

     (v)   Power absorber.

 Only electric power absorbers shall be used unless alternatives are approved by the Department.

 (vi)  Power absorber accuracy.

 

   The accuracy of the power absorber shall be 6.25 pounds of wheel force at 15 mph and 3.75 pounds of wheel force at 25 mph or ±2% of required wheel force, whichever is greater, in direction of rotation.

   (3)  Rolls

     (i)   Size and type.

 The dynamometer shall be equipped with twin rolls. The rolls shall be coupled side-to-side. In addition, the front and rear rolls shall be coupled. The dynamometer roll diameter shall be between 8.5 and 21.0 inches. The spacing between the roll centers shall comply with the equation in paragraph (a)(3)(ii) to within 0.5 inch and -0.25 inch of the calculated value. The parasitic power losses shall be determined as indicated in §  4(b)(1)(iv). Fixed dynamometer rolls shall have an inside track width of no more than 30 inches and outside track width of at least 100 inches. Rolls moveable from side-to-side may be used if adequate measures are taken to prevent tire damage from lateral vehicle movement and the dynamometer sufficiently accommodates track widths of the full range of vehicles to be tested on the dynamometer. Alternative coupling methods, track widths, roll sizes and number of rolls may be used if approved by the Department and the Environmental Protection Agency and if adequate measures are taken to prevent tire damage from lateral vehicle movement and the dynamometer sufficiently accommodates track widths of the full range of vehicles to be tested on the dynamometer. General tire roll interface losses must be determined for alternative roll sizes, configurations and spacing.

     (ii)   Roll spacing

 Roll spacing = (24.375+D) *SIN 31.5153

 D = Dynamometer roll diameter.

 Roll spacing and roll diameter are expressed in inches.

     (iii)   Design.

 The roll size, surface finish and hardness shall be such that tire slippage is minimized under all weather conditions; that water removal is maximized; that the specified accuracy of the distance and speed measurements are maintained; and that tire wear and noise are minimized.

   (4)  Inertia.

 The dynamometer shall have a total test inertia weight of 2,000 pounds ±40 pounds. Any deviation from the 2,000 pound base inertia shall be quantified and the coast-down time shall be corrected accordingly. Any deviation from the stated inertia shall be quantified and the inertia simulation shall be corrected accordingly.

     (i)   Mechanical inertia.

Insert a throttling valve in the vacuum side of the sampling system. With the gas flowing (still at atmospheric pressure), restrict the sample flow until: (1) the low flow indication is activated, (2) the response time of the slowest NDIR channel exceeds 11 seconds to 90% of the base reading, or (3) the actual gas reading differs from the base reading on any channel by more than 3% of the base reading.

 

   Acceptance criteria: The low flow indication is activated and the response times of all NDIR channels are 13 seconds or less to 90% of the base readings, and the actual gas readings differ from the base readings by 3% of the base readings or less.

   (2)  If the low flow sensor is activated by pressure (or vacuum), insert A 0-10 PSIG (0-30 in. HG) gauge between the throttling valve and the inlet O the low flow sensor.

   Acceptance criteria: The difference between the activation point and deactivation point shall be no greater than 3% of the activation point pressure (or vacuum).

 D. Dilution.

 The procedure for measuring flow rate dilution shall be as follows:

   (1)  Set vehicle with 1.6 liter maximum engine displacement at factory-recommended idle speed. OEM configuration exhaust system, transmission in neutral, hood up (a fan to cool the engine may be used if needed). Set idle speed not to exceed 920 RPM. (Set for 900 RPM with a tolerance ± 20 RPM.)

   (2)  With a laboratory grade analyzer system, sample the exhaust at 40 centimeters depth with a flow sample rate below 320 liters per hour. Allow sufficient time for this test. Record all HC, CO, NO, CO2 and O2 readings. A chart recorder or electronically stored data may be used to detect the point of stable readings.

   (3)  While operating the candidate analyzer system in a mode which has the same flow rate as the official test mode. Record the levels of HC, CO, NO, CO2 and O2. Ensure that the probe is installed correctly.

   (4)  Repeat step (II).

 Acceptance criteria: The flow rate on the analyzer shall not cause more than 10% dilution during sampling of exhaust of a 1.6 liter engine a normal idle. Ten percent dilution is defined as a sample of 90% exhaust and 10% ambient air. If the difference of the readings between (ii) and (iv) exceed 5% of the average of (ii) and (iv), repeat (ii), (iii), and (iv); otherwise average (ii) and (iv) and compare with (iii). If (iii) is within 10% of the average of (ii) and (iv), then the equipment meets the dilution specification.

 E. Analyzer accuracy.

Full scale is defined in §  3(c)(3).

   (1)  Introduce the gases in ascending order of concentrations, through the probe, beginning with the zero gas. Record the readings of the standard and candidate instruments to each concentration value.

   (2)  After the highest concentration has been introduced and recorded, introduce the same gases to the standard and candidate analyzers in descending order, including the zero gas. Record the reading of analyzers to each gas, including negatives (if any).

   (3)  Repeat steps A and B for the candidate only, four more times (total of five times).

   (4)  Calculations:

 a. Calculate the average value of each concentration for the readings of the standard instruments.

 b. Calculate the mean and standard deviation of each candidate’s readings for each concentration. Include both upscale and down scale readings for the same gas concentration. (All calculations may not be possible for zero concentrations.)

 d. For each concentration, compute the following:

     (i)   Y1 = X + KSD

     (ii)   Y2 = X - KSD

 Where:

 KSD = STD DEV * 3.5 for zero and the highest concentration value.

 KSD = STD DEV * 2.5 for all other concentration values, and

 X = Mean (arithmetic average) of the set of candidate readings.

 e. Compute the uncertainty (U) of the calibration curve for each concentration as follows:

     (i)   U1 = Concentration value - Y1

     (ii)   U2 = Concentration value - Y2

 Acceptance criteria: (1) for each concentration, the differences calculated in Step 3 shall be no greater than the accuracy tolerances specified in §  3(c)(3). (2) for each concentration, the uncertainties, (U1 and U2) shall be no greater than the accuracy tolerances required in §  3(c)(3).

 F. Analyzer system repeatability.

 This test characterizes the ability of the instrument to give consistent readings when repeatedly sampling the same gas concentration.

   (3)  Measure the elapsed time required for the instrument display to read 90% of the final stabilized reading for HC, CO, CO2 and NO. (Optional: also, measure the time required for the O2 analyzer to read 0.1% O2). Alternatively, the bench outputs may be recorded against a time base to determine the response time. Record all times in seconds.

   (4)  Switch the solenoid valve to purge with zero air for at least 40 seconds but no more than 60 seconds.

   (5)  Measure the elapsed time required for the NO instrument display to read 10% of the stabilized reading in Step (3).

   (6)  Repeat steps (1), (2) and (3), two more times (total three times).

 Acceptance criteria: The response (drop time for O2 and NO. Rise time for HC, CO, CO2 and NO) time shall meet the requirement specified in §  3(c)(2)(X). The response time shall also be within ± 1 second of the nominal response time supplied by the equipment supplier for use in §  5(1)(a)(i)(e).

       (H)   Vehicle type—mandatory entry, two categories designated for: passenger cars and trucks under 6,000 pounds GVWR and trucks 6,000 to 9,000 pounds GVWR. At this segment of the emission inspection, the emission inspection inspector shall proceed with the hang-up check. Upon successful completion of this check, the test may no longer be aborted requiring the emission inspector to insert the tailpipe probe and activate the Pennsylvania Emission Test automatically selecting the HC and CO standard required, plus the RPM and CO values required. Sample collectionshall require 17 seconds; validation of the sample shall require 5 seconds; and emission sampling immediately after validation shall require 10 seconds.

       (I)   RPM reading (auto)—actual reading, display suppressed during emission test.

       (J)   Hydrocarbon (HC, auto)—reading in PPM, display suppressed during emission test.

       (K)   Carbon Monoxide (CO, auto)—reading in %, display suppressed during emission test.

       (L)   Carbon Dioxide (CO, auto)—reading in %, display suppressed during emission test.

       (M)   Invalid test (auto)—display suppressed, during emission test.

 Four categories designated for:

 CO pass/RPM pass;

 CO pass/RPM fail;

 CO fail/RPM pass;

 CO fail/RPM fail.

       (N)   Pass/fail (auto)—display suppressed, during emission test.

 Four categories designated for:

 HC pass/CO pass;

 HC pass/CO fail;

 HC fail/CO pass;

 HC fail/CO fail.

 The automatic test results (auto) suppressed during the Pennsylvania emission test may be displayed after the information is automatically stored. This is an optional feature which may be provided by the manufacturer.

       (O)   Emission inspection fee—mandatory entry.

       (P)   Emission adjustment or repair performed—adjustment or repair indicator (Mandatory entry for retest entry, displayed only if retest is entered).

       (S)   Manufacturer’s ID (auto)—2 alpha-numeric characters assigned by the Department.

     (iii)   Data shall be entered by a Certified Emission Inspection Inspector by the alpha-numeric keyboard in the sequence specified:

 Mandatory entry data shall be completed before being allowed to proceed to the next data entry item, nonmandatory entry data are only required as specified. After completing the vehicle type entry the HC hang-up check shall be activated. Upon successful completion of this check the Emission Inspector may no longer abort the test and shall insert the probe into the subject vehicle’s tailpipe and activate the Pennsylvania Emission Test. This shall automatically activate the collection, validation and emission sampling, and automatically key appropriate HC, CO, CO2 and RPM limits, for pass/fail and invalid test decisions. The entry items designated display suppressed during emission test may not be shown on the display until the test is completed. Test data shall be automatically entered directly into storage and printed on the consumer reports. Data entry items designated field programmed by manufacturer shall be capable of programming changes to meet Emission I/M program required changes.

     (iv)   The analyzer shall be capable of use as a diagnostic tool and shall also be capable of testing for RPM, HC, CO and CO2, providing corresponding screens for diagnostic use when not activated in the Pennsylvania Emission Test.

     (v)   The keyboard shall be designed to accommodate the working environment of inspection facilities and to allow for wearing of gloves and contact with grease and oil compounds. The unit shall have the capacity to accommodate 16 present emission standards which may be changed by regulation.

     (vi)   The keyboard shall provide a capability function so that as data is improperly entered it can be corrected. The automatically-auto-entered data may not be affected by this function.

     (vii)   When the data is transferred from the storage medium, the unit shall provide the following test after loading the replacement storage medium.

 (a)  Record a predetermined test record as in subparagraph (ii) in which all number fields are filled with the number ‘‘one’’ and all alpha and alpha-numeric field are filled with the letter ‘‘A.’’

 (b)  Stop recording.

 (c)  Read the predetermined test record now on the storage medium.

 (d)  Compare the predetermined test record on the storage medium with the predetermined record in memory:

 (e)  Prohibit the instrument from further recording on the storage medium and cause the instrument to indicate this storage medium failure to the operator if the predetermined test record does not correspond directly to that in the memory.

 (f)  Permit the system to proceed if the predetermined test record in the storage medium corresponds directly to that in the memory.

     (viii)   The hydrocarbon (HC) hang-up reading in the sampling system may not exceed 20 PPM hexane before each test as measured by the analyzer zeroed on room air. The analyzer shall be designed for automatic HC hang-up checks of the sampling system using room air. The analyzer shall have a selector switch, button with indicator light labeled ‘‘hang-up check’’ or other equivalent display prompter/indicator. Hang-up activation shall cause the analyzer to automatically sample room air through the sample line and probe. The check system shall continue to sample room air until the HC response is below 20 PPM hexane. When the HC level stabilizes below this value, an indication that testing may begin shall be displayed. The analyzer shall be precluded from operating until the HC level is met. The analyzer shall also be locked out unless a successful hang-up check has been performed since the last activation of the test sequence or the HC analyzer has not experienced an HC level greater than that specified in this subparagraph.

     (ix)   Engine tachometer/idle lockout shall be treated as follows:

 (a)  A digital tachometer shall be integrated with the console for the purposes of measuring engine speed according to the number of cylinders indicated 1 through 12 cylinder vehicles, in the data entry section. The hook-up to the engine shall be by means of an inductive pick-up.

 (b)  The following table provides maximum engine RPMs allowable according to number of cylinders:

     (i)   Maximum idle speeds (shall be field programmed by the manufacturer).

     (ii)   More than 4 cylinders 1200 RPM maximum.

     (iii)   Four or less cylinders 1600 RPM maximum.

 (c)  A lock-out feature shall apply only to vehicles tested in the inspection mode and shall be provided in the tachometer that will cause an ‘‘invalid test’’ to occur and to be displayed, printed and stored if the test idle speed range is exceeded or if the speed fluctuates in excess of 20% of the reading. This data shall be field programmed by the manufacturer.

     (x)   The analyzer shall be equipped with an antidilution feature to identify vehicle exhaust system leaks and sample dilution. The technique for identifying leaks is monitoring the CO2 levels in the exhaust. If the CO2 reading is less than the lower limit, the analyzer shall display, print and store ‘‘invalid’’ test indication. The minimum acceptable CO2 values shall be field programmed by the manufacturer. At least two lower-limit CO2 values shall be capable of being used:

 (a)  Vehicle equipped with air pump: 4%.

 (b)  Vehicle without air pump: 6%.

     (xi)   In the record mode, if the space on the storage medium available for recording is not sufficient to record the entire test and information as specified in subparagraph (ii), the test may not proceed and the analyzer shall immediately lock out the testing mode of the analyzer until the manufacturer or service provider replaces the storage medium. The emission inspector shall be prohibited from replacing the storage medium.

     (xii)   The data collection system shall provide to the emission inspection inspector a visual display of the data as it is being entered, except for that data which is required under aubparagraph (ii) to be suppressed during the emission test.

     (xiii)   The analyzer system shall have the capability to provide an electronic-mechanical span/zero check every hour. If the check is not made or fails either span or zero (gas calibration or electrical component failure), the analyzer shall automatically lock out any capability of activating an emission test until the analyzer is properly adjusted or repaired. In addition, gas span checks or leak checks, checked on a weekly basis (180 calendar hours), which fail shall cause the analyzer to automatically lock out any capability of activating an enhanced emission test until the analyzer is properly adjusted or repaired.

   (3)  Vehicles shall fail the evaporative system pressure test if the system cannot maintain a system pressure above 8 inches of water for 2 minutes after being pressurized to 14 +/- 0.5 inch of water or if no pressure drop is detected when the gas cap is loosened as described in this section. Additionally, vehicles shall fail the evaporative test if the canister is missing or obviously damaged, if hoses are missing or obviously disconnected, or if the gas cap is missing.

   §  2. Evaporative System Function Tests.

 (a)  Evaporative system pressure test, the evaporative system pressure test procedure shall be as follows:

   (1)  An evaporative system pressure test shall be performed on 1981 and newer model year subject vehicles.

   (2)  The test sequence shall consist of the following steps:

     (i)   Test equipment shall be connected to the fuel tank canister hose at the canister end. The gas cap shall be checked to ensure that it is properly, but not excessively tightened, and shall be tightened if necessary.

     (ii)   The system shall be pressurized to 14 +/- 0.5 inch of water without exceeding 26 inches of water system pressure.

     (iii)   The pressure source shall be closed off, the evaporative system sealed and pressure decay monitored for 2 minutes.

     (iv)   The gas cap shall be removed after 2 minutes and the evaporative system monitored for a sudden pressure drop, indicating that the fuel tank was pressurized.

     (v)   The inspector shall be responsible for ensuring that items that are disconnected in the conduct of the test procedure are properly reconnected at the conclusion of the test procedure. Damage done to the evaporative emission control system during this test shall be repaired at the expense of the inspection station.

   (3)  Vehicles shall fail the evaporative system pressure test if the system cannot maintain a system pressure above 8 inches of water for 2 minutes after being pressurized to 14 +/- 0.5 inch of water or if no pressure drop is detected when the gas cap is loosened as described in this section. Additionally, vehicles shall fail the evaporative test if the canister is missing or obviously damaged, if hoses are missing or obviously disconnected, or if the gas cap is missing.

 (b)  Fuel filler (gas) cap test. The fuel filler (gas) cap test procedure shall be as follows:

   (1)  A fuel filler (gas) cap integrity test shall be performed on 1981 and newer vehicle either as part of the evaporative system pressure test or as a stand alone test.

   (2)  The stand alone test will be conducted using test equipment approved by the Department.

   (3)  If the fuel filler (gas) cap was tested using stand alone test equipment, the cap shall be pressurized to a pressure of 28 inches, +/- 1.0 inches.

   (4)  The flow shall be turned off and the decay or pressure monitored for up to 2 minutes.

   (5)  If at any time during the 2 minutes of the fuel filler (gas) cap test the pressure drops from the starting pressure by more than 6 inches of water, the test shall be terminated and the vehicle shall be determined to fail the fuel filler (gas) cap test. If the pressure does not drop more than 6 inches during the test, the vehicle shall pass the gas cap test.

 (c)  Subsequent test procedures and equipment approved by the EPA. If the EPA develops or approves other emission test procedures or equipment, including test procedures or equipment prescribed in this section, the Department may adopt the subsequently approved emission test procedures and equipment consistent with section 4706(e) of the Vehicle Code (relating to prohibition of expenditures for the Emission Inspection Program.
