Standard Practice for Fluorescent UV Exposure of Plastics
|Publication Date:||10 January 1999|
|ICS Code (Plastics in general):||83.080.01|
1. Scope *
1.1 This practice covers specific procedures and test conditions that are applicable for fluorescent UV exposure of plastics conducted in accordance with Practices G 151 and G 154. This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results.
NOTE 1--Previous versions of this practice referenced fluorescent UV devices described by Practice G 53, which described very specific equipment designs. Practice G 53 is being 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. Practice G 53 will be balloted for withdrawl before December 2000.
1.2 The values stated in SI units are be regarded as standard. The values given in parentheses are for information only.
1.3 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.
NOTE 2--This practice is technically equivalent to ISO 4892-3.
