ASTM D5208-01

Standard Practice for Fluorescent Ultraviolet (UV) Exposure of Photodegradable Plastics

SCOPE
1.1 This practice covers the specific procedures applicable for fluorescent Ultraviolet (UV) exposure of photodegradable plastics conducted in accordance with Practices G 151 and G 154. This practice also covers the preparation of test specimens and the evaluation of test results.
Note 1—Previous ersions of this practice referenced fluorescent UV devices described by Practice G 53, which described very specific equipment designs. Practice G 53 has been withdrawn and replaced by Practice G 151, which describes performance criteria for all exposure devices that use laboratory light sources and by Practice G 154, which gives requirements for exposing nonmetallic materials in fluorescent UV devices.
1.2 Practice D 4329 covers fluorescent UV exposures of plastics intended for long term use in outdoor applications.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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 2—There is no ISO standard equivalent to this practice.
