Full title and description

STB BS ISO 15585-2019 — Hard coal — Determination of caking index. This document (ISO 15585:2019, adopted as BS ISO 15585:2019 in the British/BSI catalogue and sometimes listed in national catalogues with local prefixes) specifies a laboratory method to determine the caking index of hard (bituminous) coal for evaluation of its caking/coking behaviour. It is intended for use where vitrinite random reflectance (Rr) is greater than 0.6 % and less than or equal to 1.8 %.

Abstract

ISO 15585:2019 describes a standardized test procedure to measure the caking index of hard coal — a parameter used to assess the tendency of coal to agglomerate and form a coherent mass when heated. The method defines sample preparation, test conditions, calculation of the caking index and reporting requirements to ensure repeatable, comparable results between laboratories and industry users. The British adoption (BS ISO 15585:2019) reflects the same technical content as the ISO edition.

Scope

This standard specifies a laboratory method for determining the caking index of hard bituminous coal. It is applicable to bituminous coals with vitrinite random reflectance (Rr) > 0.6 % and ≤ 1.8 %. The method provides requirements for sample preparation, testing procedure, calculation and reporting of the caking index so that results are fit for comparison and industrial decision-making (e.g., blending, process control and quality assessment for coking coal).

Key topics and requirements

• Definition of caking index and its significance for coking behaviour of hard coal.
• Applicability limits by vitrinite random reflectance (Rr > 0.6 % and ≤ 1.8 %).
• Detailed sample handling and preparation steps to obtain representative test portions.
• Standardised test procedure (heating/treatment conditions) to produce and assess the caked mass.
• Calculation method for the caking index and required reporting elements (test conditions, sample ID, results, uncertainty considerations).
• Requirements intended to ensure inter-laboratory reproducibility and comparability of results.

Typical use and users

Users include coal testing laboratories, coke producers, coal merchants/traders, mine quality-control teams, research labs studying coal behaviour, and standards/accreditation bodies. Typical uses are coal classification, quality control for coking/blending, acceptance testing, and support to process design where coal caking properties affect downstream metallurgical operations.

Related standards

ISO 15585:2019 replaces ISO 15585:2006 (previous edition). Related documents include other coal analysis and solid fuel testing standards under ICS 73.040 and the portfolio of methods maintained by ISO/TC 27 (Solid mineral fuels) and its subcommittees. National/adopted versions (BS ISO) provide the same technical content packaged for national use.

FAQ

Q: What is this standard?

A: ISO 15585:2019 (published as BS ISO 15585:2019 for the British adoption) is a standardized laboratory method for determining the caking index of hard coal to assess its coking/agglomerating properties.

Q: What does it cover?

A: It covers sample preparation, the specific test procedure, calculation of the caking index and reporting requirements for hard coals with vitrinite random reflectance greater than 0.6 % and up to 1.8 %. The aim is repeatable and comparable test results across laboratories.

Q: Who typically uses it?

A: Coal laboratories, coke producers, mining quality-control teams, traders and researchers concerned with coal caking/coking properties, and conformity assessment bodies. It supports product specification, acceptance testing and process control.

Q: Is it current or superseded?

A: ISO 15585:2019 is the current second edition (replacing the 2006 edition). The ISO listing shows the 2019 edition as the active/recent edition; national BS adoption is listed under BS ISO 15585:2019. Users should check their national catalogue for adoption details and for any later amendments or confirmations.

Q: Is it part of a series?

A: It is part of the family of standards and test methods for solid mineral fuels under ISO/TC 27 (ICS 73.040). While not a numbered multipart series, it is related to other coal testing standards covering proximate/ultimate analysis, petrographic methods and other physical property tests.

Q: What are the key keywords?

A: caking index, hard coal, coking coal, vitrinite reflectance, coal testing, ISO 15585, BS ISO 15585.
