SAE J1967 pdf download.(R) Retroreflective Materials for Vehicle Conspicuity.
This SAE Recommended Practice applies to retroreflective materials that are used on truck tractors and trailers 2032 mm or more in overall width and with a Gross Vehicle Weight Rating (GVWR) over 4536 kg. and school buses. The retroreflective materials for the truck tractors and trailers are super-high-intensity materials containing microprisrns. The retroreflective materials for school buses may contain flexible non. exposed glass bead lens or micropnsms
1.1 Purpose—This document establishes test procedures and related requirements for identifying and evaluabng retroreflective materials intended for use in passive devices used to enhance the conspicuity 01 vehicles at nighttime.
Conspicuity materials meeting the requirements of this document are Intended to be In compliance with FMVSS-108 which references ASTM 0 4956 Type V materials, The specifications in this document are not intended to apply to materials used for commercial identification, advertising, or similar graphics. Their use is outside the scope of this document. School bus reiroreflective materials specified in this document are intended to comply with the requirements of FMVSS-217 and FMVSS-131.

3. Definitions
3.1 Conspicuily—The ability of an object to be noticed and recognized without confusion or ambiguity.
3.2 DaytIme—The period when an object is diuminated primarily by natural sunlight, either direct or diffused by weather or clouds; the period when headlamps are not required for road illumination.
3.3 GraphIcs—Markings, illustrations, or other Identifying devices on observable surfaces of a vehicle.
3.4 Passive Devices—Devices which require no electrical power or internal illumination, but which are instead made visible by retroreflection from external light sources.
3.5 NIghttime—The period when an object Is illuminated solely or primarily by artificial light, such as the headlamps of the vehicle of the observer, The period when headlanips are required to be illuminated.
3.6 Retroreflectlon—The process by which illumination is returned by an object directly or generally back to the source of that illumination; reflection characterized by the flux in an incident beam being returned in directions dose to the direction from which it came, this effect occurring over a wide range of incidence angles.
