ASTM G147-96

Standard Practice for Conditioning and Handling of Nonmetallic Materials for Natural and Artificial Weathering Tests

SCOPE
1.1 This practice covers specimen preparation, identification, packing, shipping, handling, and conditioning before, during, and after natural and artificial weathering testing.  
1.2 This practice includes details on the conditioning of specimens after exposure and before examination. This practice also covers long-term storage of file specimens.  
1.3 Conditioning in this practice does not refer to the specific act of exposing the specimens to the weathering factors.  
1.4 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.
