(Practice)Standard Practice for Xenon Arc Exposure of Plastics Intended for Outdoor Applications
Standard Practice for Xenon Arc Exposure of Plastics Intended for Outdoor Applications
SCOPE
1.1 This practice covers procedures applicable when Practice G26 is employed for exposure of plastics. Reference is made to sample preparation and evaluation of test results.
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-Practice D2565 and ISO/DIS4892 are related in title and in technical content. However, the user should note that there may be significant technical differences. ISO/DIS4892 permits the use of different instruments and different procedures among users.
