The scope of this SAE Recommended Practice is to provide a simple@ practical@ and broadly applicable test procedure for appraising luminous Illuminant A reflectance of enhanced reflecting safety glazing materials for road vehicles. Field of Application This test procedure applies to conditions where feasibility@ rather than accuracy of measurement@ is of prime importance. Measurements can be made outside laboratories in a quality control environment and in similar applications@ when glazings@ instead of small test specimens@ have to be tested. Rationale This document was revised in accordance to the harmonization of Z26 and ISO regulations.
