ASTM D4459-99 - 10.1.1999
 
1. Scope

1.1 This practice covers the procedure applicable when Practice G26, Method C, is employed for exposing plastics to a Xenon lamp, in attempting to predict long-term color-fastness of plastics for use in indoor areas. Such exposure may involve illumination from fluorescent, incandescent, or window-filtered sunlight sources, and thermal radiation.

1.2 This standard does not purport to address all of the safety problems, 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.

Note 1-There is no similar or equivalent ISO standard.
