ASTM D1429-08

Standard Test Methods for Specific Gravity of Water and Brine

SIGNIFICANCE AND USE
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.
SCOPE
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—Balance12 to 16, 21 Test Method C—Erlenmeyer Flask17 to 21 Test Method D—Hydrometer22 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  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.
