ASTM D5142

Proximate Analysis of the Analysis Sample of Coal and Coke by Instrumental Procedures

Applicability: ASTM D5142 is applicable to the proximate analysis of coal and coke samples using instrumental methods to determine moisture, volatile matter, and ash, and to calculate fixed carbon. It is specifically for the analysis sample of coal and coke, prepared according to other ASTM standards like D2013 and D346.

Purpose: ASTM D5142 is a standard test method for the instrumental determination of proximate analysis components—namely, moisture, volatile matter, ash, and fixed carbon—in coal and coke. Its purpose is to provide a quick, automated way to analyze these properties for purposes such as determining the rank of coal, evaluating its suitability for burning, or establishing its value for commercial transactions.
