Standard Practice for Enclosed Carbon-Arc Exposures of Plastics
|Publication Date:||10 January 1999|
|ICS Code (Plastics in general):||83.080.01|
1.1 This practice covers specific procedures and test conditions that are applicable for exposure of plastics in enclosed carbon-arc devices conducted in accordance with Practices G 151 and G 153. This practice also covers the preparation of test specimens, the test conditions suited for plastics, and the evaluation of test results.
NOTE 1--Enclosed carbon-arc exposures are described in Practice G 23, which described very specific equipment designs. Practice G 23 is being replaced by Practice G 151, which describes performance criteria for all exposure devices that use laboratory light sources, and by Practice G 153, which gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices. Practice G 23 will be balloted for withdrawal before December 2000.
1.2 This practice does not cover filtered open-flame carbon-arc exposures of plastics, which are covered in Practice D 1499. Practice D 5031 describes enclosed carbon-arc exposures of paints and related coatings.
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 not equivalent to any ISO practice for laboratory accelerated exposures of plastics.
