ASTM D4674-02 - 10.4.2002
 
1. Scope

1.1 This test method covers an accelerated procedure intended to determine the resistance to color change of plastics in typical office environments, where overhead fluorescent light and window-filtered daylight are used for illumination, and where temperature and humidity conditions are in accordance with American Society of Heating, Refrigerating, and Airconditioning Engineers (ASHRAE) recommendations for workers' comfort.

1.2 This standard does not purport to address all of the safety concerns, is 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. Specific precautionary statements are given in Section 6.
