Determination of the density or relative density of petroleum and its products is necessary for the conversion of measured volumes to volumes at the standard temperatures of 15x00B0;C. The determination of densities at the elevated temperatures of 40 and 100x00B0;C is particularly useful in providing the data needed for the conversion of kinematic viscosities in centistokes (mm2/s) to the corresponding dynamic viscosities in centipoises (mPax00B7;s).1.1 This test method covers two procedures for the measurement of the density of materials which are fluid at the desired test temperature. Its application is restricted to liquids of vapor pressures below 600 mm Hg (80 kPa) and viscosities below 40 000 cSt (mm2/s) at the test temperature. The method is designed for use at any temperature between 20 and 100x00B0;C. It can be used at higher temperatures; however, in this case the precision section does not apply.   Note 18212;For the determination of density of materials which are fluid at normal temperatures, see Test Method D 1217.  1.2 This test method provides a calculation procedure for converting density to specific gravity. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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.【中国标准分类号】: N51【国际标准分类号】: 17_06【页数】: 7P.;A4【正文语种】:
