9、FINITIONS 3.1 Tail Lamp Lamp used to designate the rear of a snowmobile by a steady-burning, low-intensity light. 3.2 Multiple-Compartment Lamp A device which gives its indication by two or more separately lighted areas which are joined by one or more common parts such as a housing or lens. 3.3 Mult

10、iple Lamp Arrangement An array of two or more separated lamps on each side of the snowmobile which operate together to give a signal. 4. LABORATORY REQUIREMENTS 4.1 A multiple compartment lamp or multiple lamps may be used. 4.2 The following sections from SAE J575 are a part of this document. 4.2.1

11、Section 3 Definitions. 4.2.2 Section 3.2 Bulbs. 4.2.3 Section 4.1 Vibration. 4.2.4 Section 4.2 Moisture Test. 4.2.5 Section 4.3 Dust Test. 4.2.6 Section 4.4 Corrosion Test. 4.2.7 Section 4.5 Photometry. 4.2.8 Section 4.6 Warpage Test on Devices with Plastic Components 4.3 Plastic Materials Any plast

12、ic materials used in optical parts shall comply with the requirements set forth in SAE J576. SAE J279 Reaffirmed MAR2011 Page 3 of 5 4.4 Color Test The color of the light from a tail lamp shall be red. (See SAE J578.) 4.5 If the tail lamp is optically combined with another lamp such as a stop lamp o

13、r turn signal and a two-filament bulb is used, the bulb shall have an indexing base and the socket shall be designed so that bulbs with nonindexing bases cannot be used. As a matter of information, attention is called to typical sockets shown in SAE J567. 4.6 Photometric Requirements 4.6.1 All beam

14、candela measurements shall be made with the incandescent filament of the signal lamp at least 3 m (10 ft) from the photometric screen. The H-V axis shall be taken as parallel to the longitudinal axis of the vehicle. When compartments or lamps are photometered together, the H-V axis shall intersect t

15、he midpoint between the optical centers (filament). 4.6.2 Beam candela measurements of multiple compartment lamp or multiple lamp arrangements shall be made by either of the following methods: a. All compartments or lamps may be photometered together, provided that a line from the optical axis (fila

16、ment centers) of each compartment or lamp to the center of the photometer sensing device does not make an angle of more than 0.6 degree with the photometer (H-V) axis. b. Each compartment or lamp may be photometered separately by aligning its axis with the photometer and adding the value at each tes

17、t point. 4.6.3 Table 1 lists design candela requirements for a tail lamp.

19、rate, rated bulbs during testing.NOTE 2: Lamps designed to operate on the vehicle through a resistor or equivalent shall be photometered with the listed design voltage of the design source applied across the combination of resistance and filament. NOTE 3: A multiple device tail lamp gives its indica

20、tion by two or more separately lighted sections which may be separate lamps, or areas that are joined by common parts. The photometric values are to apply when all sections which provide the tail signal are considered as a unit. 5. INSTALLATION REQUIREMENTS The following requirements apply to the de

21、vice as used on the vehicle and are not part of the laboratory test requirements and procedures. SAE J279 Reaffirmed MAR2011 Page 5 of 5 Visibility of the tail lamp shall not be obstructed by any part of the vehicle throughout the photometric test angles for the lamp, unless the lamp is designed to

22、comply with all photometric and visibility requirements with these obstructions considered. Signals from lamps on both sides of the vehicle shall be visible through a horizontal angle from 45 degrees to the left to 45 degrees to the right. Where more than one lamp or optical area is lighted on each

23、side of the snowmobile, only one such area on each side need comply. To be considered visible, the lamp must provide an unobstructed projected illuminated area of outer lens surface, excluding reflex, at least 13 cm2(2 in2) in extent, measured at 45 degrees to the longitudinal axis of the vehicle. A

24、s a minimum, the taillight shall be lighted when the headlight is energized. 6. NOTES 6.1 Marginal Indicia The change bar (l) located in the left margin is for the convenience of the user in locating areas where technical revisions have been made to the previous issue of the report. An (R) symbol to the left of the document title indicates a complete revision of the report. PREPARED BY THE SAE SNOWMOBILE COMMITTEE
