4.1 Solids (nonvolatile matter) determinations of polishes, resin solutions, and wax emulsions take 2 to 4 h in accordance with Test Method D2834, not counting preparation time.

4.2 Curves of solids/refractive index provide a means for determining solids in a matter of minutes.

4.3 This practice is particularly useful for quality control and in process control for the production of polishes and polish components.

1.1 This practice covers the use of a refractometer for determining the nonvolatile matter (total solids) in floor polishes. This practice is also applicable to resin solutions and wax emulsions used in floor polishes.

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.
