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 Practice G 53 has been withdrawn and replaced by Practice G 151, which describes performance criteria for all exposure devices that use laboratory light sources, and by Practice G 154, which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 The values stated in SI units are to be regarded as the standard.
