ASTM D6349

ASTM D6349 is a test method for determining major and minor elements in coal, coke, and solid residues from the combustion of coal and coke by inductively coupled plasma—atomic emission spectrometry. It provides a standardized approach for elemental analysis where consistent results are needed for materials characterization, comparison, and reporting. By defining a common testing framework, ASTM D6349 helps support reliable laboratory work and clearer communication of analytical data across coal, coke, and combustion residue applications.

Purpose of ASTM D6349

The purpose of this standard is to establish a recognized method for measuring major and minor elements in solid fuel-related materials and their combustion residues using ICP-AES. This makes the analytical process more consistent and repeatable for laboratories working with coal and coke samples. ASTM D6349 is generally used to support controlled testing, data comparison, and technical evaluation when elemental composition is an important part of the analysis workflow.

Common use cases of ASTM D6349

ASTM D6349 is commonly used in laboratory testing environments that evaluate coal, coke, and residues generated after combustion. It is relevant when elemental composition must be determined for quality control, materials assessment, or reporting purposes. The standard is also useful in workflows that rely on inductively coupled plasma—atomic emission spectrometry equipment, where a consistent ASTM method may help align sample analysis, documentation, and result interpretation.

Why ASTM D6349 matters

This standard matters because elemental testing can directly affect how coal, coke, and combustion residues are assessed and compared. Using ASTM D6349 may help reduce variability between laboratories and improve confidence in analytical results. It is also valuable for procurement, compliance-related documentation, and quality control programs that require a clear, recognized test method. For organizations that rely on accurate elemental data, ASTM D6349 supports more dependable decision-making.
