Federal Motor Vehicle Safety Standards Lamps, Reflective Devices, and Associated Equipment

요약

This notice amends Federal Motor Vehicle Safety Standard No. 108 to specify that plastic materials used in reflex reflectors show not more than 7 percent haze after a 3-year outdoor exposure test, a level at which haze becomes discernable to the naked eye. This amendment will not change the stringency of the standard as it has been applied, but it will increase its objectivity. NHTSA has not adopted its proposal that cumulative haze not exceed 7 percent when a plastic lens is placed in front of a reflex reflector. Instead, the same haze criterion is applied to the reflex reflector and outer lens material. This approach will limit cumulative haze to about the same level without the need to retest current materials.
