Significance and Use
This test method provides an accurate and reliable method to measure the total calorific value of a fuel gas, on a continuous basis, which is used for regulatory compliance, custody transfer, and process control.
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:
ICS Number Code 17.200.10 (Heat. Calorimetry); 75.160.30 (Gaseous fuels)
UNSPSC Code 15111500(Gaseous fuels)
