ASTM D3761用氧弹燃烧/离子选择电极法测定煤中总氟含量标准试验方法

ASTM D3761 Standard Test Method for Total Fluorine in Coal by the Oxygen Bomb Combustion/Ion Selective Electrode Method
ASTM D3761 用氧弹燃烧/离子选择电极法测定煤中总氟含量标准试验方法

This test method permits measurement of the fluorine content of coal for the evaluation of potential fluorine emission from coal combustion or conversion processes. When coal samples are combusted in accordance with this test method, the fluorine is quantitatively retained and is representative of the total fluorine concentration in whole coal.

1. Scope
1.1 This test method covers the analysis of total fluorine in coal.
1.2 This test method was successfully tested on coals containing 25 % ash or less.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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. For specific hazard statements, see Section 7.
1.5 All accountability and quality control aspects of Guide D4621 apply to this test method.
