Phạm vi áp dụng / Scope of standard

1.1 This test method covers the determination of the bulk density of manufactured articles of carbon and graphite of at least 500 mm³ volume. The bulk density is calculated to an accuracy of 0.25 %, using measurements of mass and dimensions in air at 25 °C ± 5 °C.

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

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
