1. Scope

1.1 This practice covers specific procedures and test conditions that are applicable for xenon arc exposure of photodegradable plastics conducted in accordance with Practices G 151 and G 155. This practice also covers the preparation of test specimens, the test conditions best suited for photodegradable plastics, and the evaluation of test results.

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.

This practice is technically equivalent to ISO 4892-2 and Practice D 2565 which cover xenon arc exposures of plastics intended for long term use in outdoor applications.
