(Practice)Standard Practice for Calculating Volume-Temperature Correction For Coal-Tar Pitches
Standard Practice for Calculating Volume-Temperature Correction For Coal-Tar Pitches
SIGNIFICANCE AND USE
5.1 Coal tar pitch is shipped or stored, or both, at various temperatures, consequently a means is required to correct volume to a specified temperature.
SCOPE
1.1 This practice covers calculation of the amount of expansion or contraction of a volume of liquid coal-tar pitch due to a change of temperature.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
