ASTM C838-16

4.1 This test method provides a means of determining bulk density on as-manufactured logs, blocks, or shaped articles.

4.2 This test method is suitable for manufacturing control and acceptance specifications.

4.3 Test Method C559 may be used when a higher degree of accuracy is required.

1.1 This test method covers the determination of the density of as-manufactured carbon and graphite from measurements of mass and dimensions at room temperature.

1.2 This test method is applicable to boronated carbon and graphite.

1.3 This test method is not applicable to carbon- and graphite-containing materials that are thermally unstable at or below temperatures of 200 °C.

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

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.
