ASTM International Subcommittee D05.21 on Methods of Analysis is developing ASTM WK22936 - Test Method for Determination of Sulfur Forms in Coal by inductively coupled plasma-atomic emission spectroscopy (ICP-AES).

According to Colin Campbell, D05 member, ASTM WK22936 will be based on ASTM D2492 - Test Method for Forms of Sulfur in Coal but will be focused on reducing the required sample sizes.

Gravimetric and atomic absorption detection methods used in ASTM D2492 will be replaced in the proposed new standard with ICP-AES.

The proposed standard will also provide an optional means of directly measuring the organic sulfur fraction using high temperature combustion, according to ASTM.

The proposed test method would be used in the evaluation of coal preparation and processing operations designed to reduce coal sulfur levels.

Subcommittee D05.21 is part of ASTM Committee D05 on Coal and Coke.
