Full Description

1.1This test method describes a simplified procedure for the measurement of density or relative density of pure liquid chemicals for which accurate temperature expansion functions are known. It is restricted to liquids having vapor pressures not exceeding 79 993 Pascal (0.800 bar, 600 mm Hg (0.789 atm) at the equilibration temperature, and having viscosities not exceeding 15 cSt at 20C.

1.2Means are provided for reporting results in the following units:

Density g/cm at 20C

Density g/mL at 20C

Relative density 20C/4C

Relative density 15.56C/15.56C

Note 1:This test method is based on the old definition of 1 L = 1.000028 dm (1 mL = 1.000028 cm). In 1964 the General Conference on Weights and Measures withdrew this definition of the litre and declared that the word litre was a special name for the cubic decimetre, thus making 1 mL = 1 cm exactly.

Note 2:An alternative method for determining relative density of pure liquid chemicals is Test Method D4052.

1.3In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This 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. Specific hazard statements are given in Section 8, Hazards.

1.6This 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.
