ASTM D1455-87(2015)
(Test Method)Standard Test Method for 60° Specular Gloss of Emulsion Floor Polish
Standard Test Method for 60° Specular Gloss of Emulsion Floor Polish
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.
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.

3.1.1 specular gloss—the ratio of reflected to incident light, times 1000, for specified apertures of illumination and reception
when the axis of reception coincides with the mirror image of the axis of illumination.
4. 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

Test Methods D1436.
6. Substrates
6.1 Two standard substrates are commonly used; however, commercial types may be used to test specific applications. Better
agreement of results can be expected when black glass is used as the substrate, except for those cases where the sample being tested
produces a hazy film. Where a hazy film is produced, black glass should not be employed as the substrate. The standard types are
