scope:

1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in fluorescent UV and condensation devices conducted according to Practices G 151 and G 154. This practice also covers the preparation of test specimens, and the evaluation of test results. describes commonly used test conditions.

Note 1--Previous versions of this practice referenced fluorescent UV devices described by Practice G 53, which described very specific equipment designs. Practice G 53 has been withdrawn and replaced by Practice G 151, which describes performance criteria for all exposure devices that use laboratory light sources, and by Practice G 154, which gives requirements for exposing nonmetallic materials in fluorescent UV devices.Note 2--ISO 11507:1997 also describes fluorescent UV-condensation exposures of paints and coatings.

1.2 This standard does not purport to address all of the safety problems 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.
