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.

Note 1—Test Method D 4052 describes an instrumental procedure.

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 E 12, 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in these test methods with the exception of Fahrenheit (°F) in 5.1 as an example of a possible industrial specification unit.

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.

1.5 Review the current Materials Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, handling, and safety precautions.
