Scope

This weathering apparatus is used for comparing the weathering characteristics of bituminous materials against a reference material in which the outdoor weathering characteristics are known. It is not possible to establish a precise correlation between accelerated and natural weathering because of geographical climatic variations, local weather variation from normal, and local pollutants. Guide G 141 provides guidance regarding this issue.

1.1 This practice describes test conditions and procedures for fluorescent UV and condensation exposures conducted according to Practices G 151 and G 154 for bituminous roofing and waterproofing materials that have a minimum softening point of approximately 95176;C (200176;F) as determined by Test Method D 36. (Also see Terminology G 113.)

1.2 The values stated in SI units are to be regarded as the 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.
