| 1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
1.1 This test method covers the determination with the continuous recording calorimeter (Note 1) of the total calorific (heating) value of fuel gas produced or sold in the natural gas range from 900 to 1200 Btu/standard ft3. Note 1: An extensive investigation of the accuracy of the
Cutler-Hammer recording gas calorimeter, when used with gases of
high heating value, was made by the National Bureau of Standards in
1957 under a research project sponsored by the American Gas
Association.
1.2 The subjects covered in this test method appear in the following sections:
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 and health 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. |
