ASTM D891-95(2000) PDF

1.1 These test methods cover the determination of the specific gravity, apparent, of liquid industrial chemicals. Two test methods are covered as follows:

1.1.1 Test Method A , specific gravity, apparent, by means of a hydrometer.

1.1.2 Test Method B , specific gravity, apparent, by means of a pycnometer.

1.2 In common usage the term specific gravity, apparent, is understood to mean specific gravity. Since this test method is to be in conformity with Terminology E12, all terms reading specific gravity were changed to specific gravity, apparent, without altering the meaning of specific gravity and, the term apparent could be dropped in everyday operations after establishing the use term equivalency.

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.
