適用范圍： This test method describes procedures for the measurement of gloss of plastic films and solid plastics, both opaque and transparent. It contains four separate gloss angles (Note 1): 60-deg, recommended for intermediate-gloss films, 20-deg, recommended for high-gloss films, 45-deg, recommended for intermediate and low-gloss films, and 75-deg, recommended for plastic siding and soffit. Note 1 -The 75-deg, 60-deg, and 20-deg apparatus and method of measurement duplicate those in Test Method D 523; those for the 45? procedure are similarly taken from Test Method C 346. 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. Note 2 -There is no similar or equivalent ISO standard.
