Whiteness index obtained from reflectance measurements on exaggerated dried polish films on filter paper can be used as a measurement of the color of such films.
Whiteness index may be useful in predicting the potential discoloring effect of polish films on flooring substrates.
Whiteness index should be useful in specifications when color comparisons are made with a standard sample polish.
1.1 This test method covers comparing colors of films (or solids) deposited from the emulsified particles in water emulsion floor polishes. It is based upon luminous reflectance measurements made with tristimulus colorimeters such as the Hunter Color Difference Meter.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
