Full title and description

ASTM D3174-12(2018)e1 — Standard Test Method for Ash in the Analysis Sample of Coal and Coke from Coal. This test method defines the procedure for determining the inorganic residue (ash) remaining after combustion of a prepared coal or coke analysis sample and includes the 2018 editorial/revision update (e1).

Abstract

This standard specifies laboratory procedures to determine ash content in analysis samples of coal and coke prepared per applicable sampling practices. Results are used in proximate and ultimate analyses and reference other ASTM methods for constituent and trace-element determinations. The method gives SI units as standard and includes safety and applicability notes.

Scope

The standard covers determination of the inorganic residue (ash) in analysis samples of coal or coke prepared according to Practices D2013 or D346. Results are applicable to proximate analysis (Practice D3172) and ultimate analysis (Practice D3176); the standard also references specific test methods for ash constituent determinations and for preparing ash for trace-element analysis. SI units are the standard units used.

Key topics and requirements

• Definition and significance of ash as the inorganic combustion residue.
• Required sample preparation references (Practice D2013, Practice D346).
• Combustion/incineration procedure to determine ash content for analysis samples.
• Application of ash results to proximate and ultimate analyses (D3172, D3176).
• References to follow-up methods for constituent analysis (D3682, D4326, D6349) and for trace-element preparation (D6357).
• Statement that SI units are to be regarded as standard and safety/environmental responsibility of the user.

Typical use and users

Used by analytical laboratories, coal and coke producers, utilities, fuel testing facilities, environmental and regulatory bodies, and research organizations for routine proximate/ultimate analysis and quality control where accurate ash determination is required.
