Scope of standard 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:SectionsAir-Gas Ratio Test11Apparatus5Basis of Measurement14Cold Balance Test10Compensation of Complicating Factors13Condition of Gas Sample7Definitions2Installation of Apparatus6MaintenanceAppendix X1Operating PrecautionsAppendix X2Operation and Checking of Apparatus9Precision15Scope1Significance and Use4Standardization of Calorimeter12Standardization, Preliminary, of Calorimeter by Hydrogen8Summary of Test Method31.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
