ASTM D1455-87(1997)

Standard Test Method for 60&#176 Specular Gloss of Emulsion Floor Polish

SCOPE
1.1 This test method covers the determination of the 60° specular gloss of films of emulsion floor polish after application to a substrate.  Note-Specular gloss is one of several related appearance attributes that produce the sensation of glossiness. For this reason, specular gloss measurements may not always correlate well with visual rankings of glossiness.
1.2 This standard does not purport to address all of the safety problems, 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.
