Rationale: The changes provide for the use of controlled forward light scattering plastic materials, herein referred to as Diffusing Plastic Materials. Diffusing Plastic Materials can not be evaluated for durability using the conventional "increase of haze" methodology since measurement of haze as diffusing materials are not within the scope of ASTM D 1003. This new evaluation methodology is limited to Diffusing Plastic Materials only and requires a more stringent maintenance of luminous transmittance. All other existing testing and requirements remain unchanged for all materials. No changes have been made or allowed in the 2009 revision for transparent plastic materials. New definitions have been incorporated as necessary.
