1.1 This practice evaluates the resistance of nonmetallic materials to solar radiation filtered through glass. 1.2 This practice is limited to the method of conducting the exposures. The preparation of test specimens and evaluation of results are covered in various standards for the specific materials. 1.3 This practice includes two methods: 1.3.1 Method A -Continuous exposure under glass in a cabinet with passive ventilation. 1.3.2 Method B -Continuous exposure under glass in enclosed black-painted cabinet (black box under glass). 1.4 The values stated in SI units are to be regarded as the standard. 1.5 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.
