Overview
ISO 1213-2:2024 - Coal and coke - Vocabulary - Part 2: Terms relating to sampling, testing and analysis provides a standardized glossary of terms commonly used in the sampling, testing and analysis of coal and coke. This third edition updates terminology to specify coal and coke explicitly (replacing the former “solid mineral fuels” wording) and clarifies alternative names and deprecated terms where applicable. The document contains definitions for technical concepts such as sampling types, test methods, analytical results and physical properties used throughout coal and coke testing.
Key technical topics and requirements
ISO 1213-2:2024 does not prescribe test procedures but defines terminology that underpins sampling and analytical standards. Notable entries and topics include:
- Sampling terms: bulk sample, channel sample, core sample, common sample, increments, complete seam profile sample, continuous sampling, constant mass division.
- Physical and mechanical properties: abrasion, abrasion index, breakage, bulk density, apparent relative density.
- Combustion and calorific properties: gross and net calorific value (constant volume and pressure), adiabatic calorimeter.
- Ash and mineral matter: ash, ash analysis, ash fusibility, ash viscosity, base/acid ratio, adventitious ash (deprecated term).
- Coke-specific terms: coke, blast furnace coke, coke reactivity index (CRI), coke strength after reaction (CSR), abrasion value.
- Quality and measurement concepts: accuracy, bias, bias of scale, coefficient of variation, caking index.
- Notes clarify units, common measurement equipment (e.g., calorimeters) and references to sieve sizes and test conventions where present (for example, CSR retention on 10.0 mm or 9.5 mm sieves; abrasion value sieve size 0.5 mm).
Practical applications and users
This vocabulary standard supports consistent communication, reporting and contractual clarity across the coal and coke supply chain:
- Laboratories: harmonize reporting of test results and ensure consistent interpretation of terms used in methods and certificates.
- Coal and coke producers: use uniform terminology in quality control, production records and specifications.
- Buyers, traders and power utilities: reduce ambiguity in contracts and technical specifications for fuel procurement.
- Steelmakers and metallurgical coke users: apply common definitions for CRI/CSR and other coke performance descriptors.
- Regulators, inspectors and researchers: standardize terminology in regulations, audits and scientific publications.
Related standards
- ISO 1213-2:2024 is part of the ISO 1213 series; a full list of parts is available on the ISO website (www.iso.org).
- The standard contains no normative references but cross-references ISO/IEC terminology resources (ISO OBP and IEC Electropedia).
