SCOPE

1.1 This test method covers the determination of the true specific gravity of solid materials, and is particularly useful for materials that easily hydrate which are not suitable for test with Test Method C135. This test method may be used as an alternate for Test Method C135, Test Method C128, and Test Method C188 for determining true specific gravity.

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

1.2.1 Exception-In 7.3 the equivalent SI unit is expressed in parenthesis.

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.
