Full title and description

St ISO 17246-2024 — Coal and coke — Proximate analysis. Establishes a standardized practice for proximate analysis of coal and coke to provide comparable results across laboratories and industry users, including methods for determining moisture, volatile matter, ash and calculation of fixed carbon for reporting and quality control.

Abstract

This International Standard defines a practice for the proximate analysis of coal and coke. It gives principles and test methods to determine the main proximate parameters (moisture, volatile matter, ash) and the calculation/statement of fixed carbon, together with requirements for sample preparation, expression of results and test reporting. The 2024 edition updates and consolidates previous editions to reflect current test practice and referenced methods.

Scope

This document establishes a practice for the proximate analysis of coal and coke. It is intended for general utilization by the coal and coke industries to provide a common basis for comparison of coals and coke and for the determination and reporting of fixed carbon. The standard covers sample preparation, the principles of the test methods used for proximate parameters, expression of results and recommended content for test reports.

Key topics and requirements

• Definitions and terms used in proximate analysis of coal and coke.
• Principles of proximate analysis and relationship to ultimate analysis.
• Requirements for sample preparation and representative subsampling.
• Test methods for determining moisture (total and analysis-sample moisture).
• Test methods for determination of volatile matter.
• Test methods for determination of ash content.
• Calculation and reporting of fixed carbon (by difference) and bases for reporting (as received, dry, dry ash-free, etc.).
• Expression of results, uncertainty considerations and required information in the test report.
• Informative annex with an example proximate analysis and reporting format.

Typical use and users

Used by industrial and commercial coal testing laboratories, power utilities, coke producers, steelworks, fuel traders, regulatory bodies and research organizations. Typical uses include quality control, contractual specification verification, fuel characterization for combustion and metallurgical processes, and routine reporting of coal/coke properties.

Related standards

Standards commonly referenced alongside ISO 17246 include standards for ultimate (elemental) analysis and related test methods and vocabulary, for example: ISO 17247 (ultimate analysis), ISO 1171 (determination of ash), ISO 562 (determination of volatile matter), ISO 589 and ISO 11722 (methods for moisture determination), ISO 1170 (calculation of analyses to different bases), ISO 1213-2 (vocabulary for sampling/testing/analysis) and other ISO/TC 27 technical outputs addressing sulfur determination and specific test-method details.
