ASTM D1455 – Standard Test Method for 60° Specular Gloss of Emulsion Floor Polish
Description:
Significance and Use
4.1 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. A20° angle measured in accordance with Test Method D523 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.
