ASTM D1756-02(2007)

Заменен
Standard Test Method for Determination as Carbon Dioxide of Carbonate Carbon in Coal (Withdrawn 2013) — 3 стр.
Причина отмены

This test method covers the determination of carbon dioxide in coal in any form, such as mineral carbonate, from which carbon dioxide is released by action of mineral acids. It applies to high-carbonate and low-carbonate coals. Formerly under the jurisdiction of Committee D05 on Coal and Coke, this test method was withdrawn in January 2013 and replaced by D6316, Test Method for Determination of Total, Combustible and Carbonate Carbon in Solid Residues from Coal and Coke.

Значение и использование

Small amounts of mineral carbonates occur in many coals and comparatively large amounts in some coals. The determination of these carbonates is the purpose of this test method. The value found for carbon dioxide is used to estimate the mineral matter content, particularly CaCO3 and MgCO3, of high-carbonate coals.

Область применения

1.1 This test method covers the determination of carbon dioxide in coal in any form, such as mineral carbonate, from which carbon dioxide is released by action of mineral acids. It applies to high-carbonate and low-carbonate coals.

1.2 The values stated in SI units are to be regarded as 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.
