   The provisions of this Subchapter O adopted September 27, 1996, effective September 28, 1996, 26 Pa.B. 4640, unless otherwise noted.

§ 175.261. Scope.

 This subchapter governs the application upon windows and wings, except roof locations, of sun screening devices, and other material which do not permit a person to see or view the inside of the vehicle, and which do not comply with FMVSS No. 205, and the application for a certificate of exemption from this subchapter.

§ 175.262. Applicability.

 This subchapter applies to vehicles which are subject to a periodic safety inspection, except those inspected in accordance with §  175.130 (relating to inspection procedure).

§ 175.263. Sun screening location.

 (a)  Windshields, side windows and side wings. A person may not operate, on a highway, a motor vehicle with a front windshield, side window or side wing that has been equipped with a sun screening device or other material which does not permit a person to see or view the inside of the vehicle. This subchapter does not prohibit the use of products or materials along the top edge of the windshield if the products or materials are transparent and do not encroach upon the AS-1 portion of the windshield as provided by FMVSS No. 205 and if the devices or materials are not more than 3 inches from the top of the windshield.

 (b)  Rear window. The rear window on a motor vehicle may be treated by the vehicle owner with a sun screening device or other material. If the rear window is treated with a sun screening device or other material, the vehicle shall comply with §  175.264 (relating to mirrors). See Table X for specific requirements for vehicles subject to this subchapter.

 (c)  Louvered materials. Louvered materials may not reduce the area of driver visibility below 50% as measured on a horizontal plane.

§ 175.264. Mirrors.

 Right and left outside rearview mirrors shall be required with the use of a sun screening device or other material unless the sun screening device or other material is only used or applied above the AS-1 portion of the windshield as permitted in §  175.263(a) (relating to sun screening location). Each mirror shall have a minimum reflective surface of 19.5 square inches, except as otherwise provided in § §  175.148(b) and 175.177(b) (relating to mirrors). A vehicle for which a certificate of exemption has been issued for medical reasons may be equipped with only a left outside rearview mirror, unless originally equipped with an outside rearview mirror on both sides of the vehicle.

§ 175.265. Exemption provisions.

 (a)  Exempt vehicles. The following vehicles are exempt from §  175.263 (relating to sun screening location):

   (1)  A hearse, ambulance or government vehicle.

   (2)  A vehicle for which a certificate of exemption has been issued by the Department under subsection (b).

 (b)  Certificate of exemption. The Department will issue a certificate of exemption from §  175.263 for the following vehicles:

   (1)  A vehicle which was registered in this Commonwealth as of September 8, 1984, and was equipped with a prohibited sun screening device or other prohibited material prior to September 9, 1984. Requests for this type of exemption shall be accompanied by an application for a certificate of exemption, made on a form furnished by the Department, which shall contain a description of the vehicle by make, year, model, vehicle identification number, windows and wings equipped with sun screening device or other material and other information as the Department may prescribe.

   (2)  A vehicle owned by a person who is afflicted with a condition for which the Department has determined, in consultation with the Medical Advisory Board, that the use of prohibited sun screening devices or other materials is justified; or a vehicle owned by a person residing with a person who is so afflicted, if the afflicted person normally drives or is driven in the vehicle. An application for a certificate of exemption will be granted only for colorless sun screening device or other material and shall be made on a form furnished by the Department, which shall contain the following:

     (i)   A description of the vehicle by make, year, model and vehicle identification number.

     (ii)   A medical certification of need due to a disability from a licensed physician or optometrist.

     (iii)   Other information as the Department may prescribe.

 (c)  Display of certificate issued for vehicles registered as of September 8, 1984. Upon compliance with the criteria in subsection (b)(1), the Department will issue a certificate of exemption which shall be carried in the vehicle at all times by the operator of the vehicle and shall be displayed upon request of a police officer. The certificate of exemption shall also be submitted to the inspection station upon submission of the vehicle for inspection.

 (d)  Display of certificate issued for medical reasons. Upon compliance with the criteria in subsection (b)(2), the Department will issue a certificate of exemption authorizing the installation of a colorless sun screening device or other material which filters ultraviolet light. This certificate of exemption shall be carried in the vehicle at all times by the operator of the vehicle and shall be displayed upon request of a police officer. The certificate of exemption shall also be submitted to the inspection station upon submission of the vehicle for inspection.

 (e)  Sale or transfer of exempted vehicle. Upon the sale or transfer of a vehicle for which a certificate of exemption has been issued under subsection (b)(2), the certificate of exemption is void. Prior to the sale or transfer of a vehicle exempted under subsection (b)(2), it is the sole responsibility of the owner or seller of the vehicle to remove sun screening devices or other materials which do not comply with Departmental regulations. The owner or seller shall destroy the certificate of exemption and provide the purchaser with a notarized statement specifying the name and address of the owner or seller, the vehicle identification number, year and model, and the business entity and process used to remove the sun screening device or other material.

APPENDIX A



MINIMUM REQUIREMENTS FOR MOTOR VEHICLE
BRAKE LININGS—SAE J998

SAE Recommended Practice

 1. Scope—This specification covers brake linings used on motor vehicles operated on the public ways, except those used only for parking brakes. The performance requirements outlined in this SAE Recommended Practice are based on currently available engineering data. It is intended that all portions of this recommended practice will be reviewed periodically and revised as additional knowledge regarding brake lining performance is developed.

 2. Purpose—The purpose of this SAE Recommended Practice is to establish minimum coefficient of friction requirements for brake linings used in the service brake system of a motor vehicle. Linings that meet these minimum friction requirements may not be suitable for use on all vehicles because of differences in brake design or application.

 3. Test Procedures—Five complete tests shall be conducted on each brake lining in accordance with the SAE J661.

 4. Brake Lining Evaluation—Brake linings shall be evaluated for normal and hot friction coefficients in accordance with SAE J866.

 5. Minimum Requirements—To meet minimum requirements a brake lining shall have:

 5.1. A normal friction coefficient over .25 based on the average of five tests.

 5.2. A hot friction coefficient over .15 based on the average of five tests.

 5.3. A coefficient of friction of .15 or over on each of the five tests at the following points:

 5.3.1. Between 200F and 550F, inclusive, on the second fade run.

 5.3.2. Between 300F and 200F, inclusive, on the second recovery run.

 5.4. Not more than a 20% or .050 variation of coefficient of friction, whichever is greater, below the average value of all five tests at each temperature point specified in paragraph 5.3.

 (Report of SAE Brake Committee approved January 1968.)

MOTORCYCLE AND MOTOR VEHICLE CYCLE
ELECTRICAL SYSTEM
(MAINTENANCE OF DESIGN VOLTAGE)—SAE J392
SAE Recommended Practice

 1. Purpose—This SAE Recommended Practice provides minimum illumination voltage values for motorcycle and motor-driven cycle electrical systems and accompanying test procedures. (Note: Wherever the word ‘‘motorcycle’’ appears in the report, it is understood to include ‘‘motor-driven cycle.’’)

 2. Scope—This recommended practice pertains to both battery-equipped and batteryless motorcycle electrical systems.

 3. Test Apparatus:

 3.1. Voltmeter—0-20 V maximum full-scale deflection, accuracy +1/2% (two voltmeters required).

 3.2. Ammeter—Capable of carrying full system load current. Accuracy +3%FS.

 3.3. Means for Measuring Engine RPM-Accuracy +3%.

 4. Test Procedure.

 4.1. Install fully charged original equipment battery on the motorcycle (if motorcycle is battery equipped).

 4.1.1. Battery temperature to be 80 + or -10F.

 4.2. Connect one voltmeter between the headlamp low beam terminal and the ground; connect the other voltmeter between the tail lamp terminal and the ground.

 4.3. Connect the ammeter in series with the battery. (Note: Disregard paragraph 4.3 for batteryless machines.)

 4.4. Start engine and turn on headlamp(s).

 4.4.1. Switch headlamp to the low beam position.

 4.4.2. External fan cooling may be applied to the motor cycle engine.

 4.5. Run the engine at an rpm equivalent to 30 mph in top gear for 10 minutes.

 4.5.1. Record the lowest and highest headlamp voltage and tail lamp voltage observed during the 10 minute period.

 4.6. Increase speed to manufacturer’s suggested maximum rpm.

 4.6.1. Record the highest and lowest headlamp and tail lamp voltages observed during a 5-second period.

 4.7. Run the engine at manufacturer’s rated idle speed for 10 minutes.

 4.7.1. Record the lowest and highest tail lamp voltage observed during the 10 minute period.

 4.7.2. Record the lowest and highest headlamp voltage observed during the 10-minute period.

 4.8. Slowly increase the engine speed until generating equipment cancels the system load, indicated by ‘‘0’’ reading on the ammeter. (Note: Disregard paragraph 4.8 for batteryless motorcycles.)

 4.8.1. Record the engine rpm at ammeter zero point.

 5. Test Limits:

 5.1. Voltages recorded in paragraphs 4.5.1, 4.6.1 and 4.7.1 shall be between 80% and 120% of the rate headlamp design voltage.

 5.2. Voltages observed in paragraph 4.7.2 shall be between 40% and 120% of the rated headlamp design voltage.

 5.3. Engine rpm observed in paragraph 4.8.1 shall be less than the motorcycle equivalent speed at 30 mph in top gear operation.
