Standard Practice for Conducting Exposures to Daylight Filtered Through Glass
|Publication Date:||1 January 2005|
|ICS Code (Textiles in general):||59.080.01|
1.1 This practice evaluates the resistance of nonmetallic materials to solar radiation filtered through glass.
1.2 For direct exposures, refer to Practice G 7.
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 AA cabinet that allows passive ventilation of specimens being exposed behind glass.
1.4.2 Type BEnclosed cabinet with exterior painted black that allows no 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.
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.
