Standard Practice for Conducting Exposures to Daylight Filtered Through Glass

active, Most Current
Publication Date: 1 December 2021
Status: active
Page Count: 6
ICS Code (Textiles in general): 59.080.01
scope:

This practice describes procedures for conducting exposures of various materials to daylight filtered through glass in passively ventilated and non-vented enclosures. For exposures in under glass enclosures with forced air circulation, refer to Practice G201.

This practice is not intended for corrosion testing of bare metals.

For direct exposures, refer to Practice G7.

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.

Exposure conducted according to this practice can use two types of exposure cabinets.

Type A-A cabinet that allows passive ventilation of specimens being exposed behind glass.

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."

Type A exposures of this practice are technically similar to Method B of ISO 877-2.

Units-The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
