1.1 This practice evaluates the resistance of nonmetallic materials to solar radiation filtered through glass in passively ventilated and non-vented enclosures. For exposures in under glass enclosures with forced air circulation, refer to Practice G201.
1.2 For direct exposures, refer to Practice G7.
1.3 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.
1.4 Exposure conducted according to this practice can use two types of exposure cabinets.
1.4.1 Type A-A cabinet that allows passive ventilation of specimens being exposed behind glass.
1.4.2 Type B-Enclosed cabinet with exterior painted black that does not provide for ventilation of specimens exposed behind glass. Exposures conducted using a Type B cabinet are typically referred to as “black box under glass exposures.”
1.5 Type A exposures of this practice are technically similar to Method B of ISO 877-2.
1.6 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.7 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.
