(Test Method)Standard Test Method for Moisture in the Analysis Sample of Coal and Coke
Standard Test Method for Moisture in the Analysis Sample of Coal and Coke
SIGNIFICANCE AND USE
5.1 Moisture as determined by this test method is used for calculating other analytical results to a moisture free basis using procedures in Practice D3180. Moisture percent determined by this test method may be used in conjunction with the air-dry moisture loss determined in Method D2013 and Test Method D3302 to determine total moisture in coal. Total moisture is used for calculating other analytical results to “as received” basis using Practice D3180. Moisture, ash, volatile matter, and fixed carbon percents constitute the proximate analysis of coal and coke.
SCOPE
1.1 This test method covers the determination of moisture in the analysis sample of coal or coke. It is used for calculating other analytical results to a dry basis. When used in conjunction with the air drying loss as determined in accordance with Method D2013 or Practice D346, each analytical result can be calculated to an as-received basis:
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 and health practices and determine the applicability of regulatory limitations prior to use.
