ASTM D3176

Standard Practice for Ultimate Analysis of Coal and Coke

Applicability: ASTM D3176 is a standard practice for the “Ultimate Analysis of Coal and Coke”. It outlines the procedures for determining the elemental composition of coal and coke samples, specifically focusing on carbon, hydrogen, nitrogen, sulfur, and ash content. This analysis is crucial for understanding the chemical makeup of these materials and their potential applications as fuels or in other processes.

Purpose: The primary purpose of ASTM D3176 is to define a standard practice for ultimate analysis of coal and coke, which involves determining the elemental composition of these materials. This includes measuring the percentages of carbon, hydrogen, nitrogen, and sulfur, as well as the ash content and estimating oxygen by difference, according to ASTM International. The ultimate analysis provides a framework for comparing different coals or cokes and assessing their suitability for various applications, such as fuel or metallurgical purposes.
