ASTM D1148-13(2018) PDF

Scope: 1.1 This test method covers techniques to evaluate the surface discoloration of white or light-colored vulcanized rubber that may occur when subjected to UV or UV/visible exposure from specified sources under controlled conditions of relative humidity, or moisture, and temperature. 1.2 This test method also describes how to qualitatively evaluate the degree of discoloration produced under such conditions. 1.3 The term “discoloration” applies to a color change of the rubber sample, as distinguished from staining (see Note 1), that refers to a color change of a metal finish in contact with or adjacent to the rubber specimen. NOTE 1—Tests for staining are covered by Test Methods D925. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
