    Significance and Use

    4.1 This weathering apparatus is used for comparing the weathering characteristics of bituminous materials against a control material for which the outdoor weathering characteristics are known. It is not possible to establish a precise correlation between accelerated and natural weathering because (1) there are geographical climatic variations, local weather variations, and variations in local pollutants, and (2) the relation between accelerated and natural weathering is material dependent. Acceleration factors differ between materials as well as between formulations of the same material. Guide G141 provides guidance regarding this issue.

    Note 1This practice can be used for other than bituminous materials, but the significance and use have not been evaluated.

    1. Scope

    1.1 This practice describes test conditions and procedures for fluorescent UV and condensation exposures conducted according to Practices G151 and G154 for bituminous roofing and waterproofing materials that have a minimum softening point of approximately 95°C [200°F] as determined by Test Method D36. (Also see Terminology G113.)

    1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

    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.
