ASTM D1455-87(2008)
(Test Method)Standard Test Method for 60° Specular Gloss of Emulsion Floor Polish
Standard Test Method for 60<span class='unicode'>°</span> Specular Gloss of Emulsion Floor Polish
SIGNIFICANCE AND USE
This test method may be used to evaluate the difference in gloss of dried films of emulsion floor polishes when the light reflected at a 60° angle is measured. Extremely high- or low-gloss polishes may not be differentiated at a 60° angle. A 20° angle measured in accordance with Test Method D 523 may give better definition of gloss.
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 1—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 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.
