ASTM D1290-95(2015)

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 and health practices and determine the applicability of regulatory limitations prior to use.

3. 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.
4. Apparatus
4.1 Centrifuge and Tubes, conforming to Paragraphs 6.1 and 6.2 on Centrifuge and Centrifuge Tubes of Test Method D1796.
