ASTM D1290-95(2021)
(Test Method)Standard Test Method for Sediment in Water-Emulsion Polishes by Centrifuge
Standard Test Method for Sediment in Water-Emulsion Polishes by Centrifuge
SIGNIFICANCE AND USE
3.1 This test method determines the amount of sediment in water-emulsion polishes. Sediment is generally believed to have negative effects on water-emulsion polish properties.
SCOPE
1.1 This test method covers the determination of sediment in water-emulsion polishes by means of a centrifuge.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
