|ICS Code (Measurement of volume, mass, density, viscosity):||17.060|
1.1 This test method covers the determination of the density of oils more viscous than 15 cSt at 20°C (mm /s), and of viscous oils and melted waxes at elevated temperatures, but not at temperatures at which the sample would have a vapor pressure of 100 mm Hg (13 kPa) or above.
Note 1-To determine the densities of less viscous liquids at 20 or 25°C use Test Method D941, or Test Method D1217.
1.2 This test method provides a calculation procedure for converting density to relative density (specific gravity).
1.3 The values stated in acceptable SI units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety problems, 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.
