【国外标准】 Standard Test Method for Density (Relative Density) of Solid Pitch (Pycnometer Method)

5.1 Values of density and relative density are used for converting volumes to units of mass as required in other ASTM standards and in sales transactions.1.1 This test method covers the determination of density and relative density by pycnometer, and can be used for pitch that can be handled in fragments.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.
