【国外标准】 Standard Test Method for Bulk Density by Physical Measurements of Manufactured Carbon and Graphite Articles

4.1 Bulk density as determined by this test method is a basic material property of importance in manufacturing and application of carbon and graphite.4.2 This test method can be used for quality and process control, material characterization and description, and other purposes.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.
