Причина отмены These test methods cover the determination of the specific gravity of water and brine free of separable oil, as follows: Test Method A—Pycnometer; Test Method B—Balance; Test Method C—Erlenmeyer Flask; Test Method D—Hydrometer.

Formerly under the jurisdiction of Committee D19 on Water, these test methods were withdrawn in July 2022 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid's characteristics compared to a standard, usually water, at a specified temperature. This will allow the user to determine if the test fluid will be heavier or lighter than the standard fluid.

1.1 These test methods cover the determination of the specific gravity of water and brine free of separable oil, as follows:

 

Sections

Test Method A—Pycnometer

 7 to 11, 21

Test Method B—Balance

12 to 16, 21

Test Method C—Erlenmeyer Flask

17 to 21

Test Method D—Hydrometer

22 to 27

1.2 Test Methods A and B are applicable to clear waters or those containing only a moderate amount of particulate matter. Test Method B is preferred for samples of sea water or brines and is more sensitive than Test Method D which has the same general application. Test Method C is intended for samples of water containing mud or sludge.

1.3 It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.

1.4 The test method was tested at 22°C over a range, shown in Tables 1-4, of 1.0252 through 1.2299; all data were corrected to 15.6°C (60°F).

1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

1.6 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.
