ASTM C604 : 02(2007)e1

Standard Test Method for True Specific Gravity of Refractory Materials by Gas-Comparison Pycnometer

Standard Details

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 C 135. This test method may be used as an alternate for Test Method C 135, Test Method C 128, and Test Method C 188 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.
