ASTM D3684用氧弹燃烧/原子吸收法测定煤中总汞量的标准试验方法

ASTM D3684 Standard Test Method for Total Mercury in Coal by the Oxygen Bomb Combustion/Atomic Absorption Method
ASTM D3684 用氧弹燃烧/原子吸收法测定煤中总汞量的标准试验方法

The possible emission of mercury that may be found in coal from coal combustion is an environmental concern.
When test portions are burned according to this procedure, the total mercury is quantitatively retained and is representative of concentrations in the whole coal.

1. Scope
1.1 This test method describes a procedure for the analysis of total mercury in coal.
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. Specific precautionary statements are given in 8.3.1.
1.2 The values stated in SI units (IEEE/ASTM SI 10) shall be regarded as the standard.
