    Withdrawn Rationale:

    This test method covers measurement of total luminous reflectance factor of opaque, nonfluorescent specimens by use of an integrating-sphere reflectometer with illumination at an angle of 30 from the surface normal and diffuse viewing with specular component included.

    Formerly under the jurisdiction of Committee E12 on Color and Appearance, this test method was withdrawn in October 2004. This standard is being withdrawn without replacement due to its limited use by industry.

    1. Scope

    1.1 This test method covers measurement of total luminous reflectance factor of opaque, nonfluorescent specimens by use of an integrating-sphere reflectometer with illumination at an angle of 30° from the surface normal and diffuse viewing with specular component included.

    1.2 This test method is intended to be used for evaluation of total luminous reflectance factor of reflector lighting sheet material. It may be used for evaluation of other material when its specific geometry has been found to be applicable.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
