| 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 ft . 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: Sections Air-Gas Ratio Test 11 Apparatus 5 Basis of Measurement 14 Cold Balance Test 10 Compensation of Complicating Factors 13 Condition of Gas Sample 7 Definitions 2 Installation of Apparatus 6 Maintenance, Appendix I X1 Operating Precautions, Appendix II X2 Operation and Checking of Apparatus 9 Precision 15 Scope 1 Significance and Use 4 Standardization of Calorimeter 12 Standardization, Preliminary, of Calorimeter by Hydrogen 8 Summary of Test Method 31.3 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. |
