ISO 1213-2:2016

Overview

ISO 1213-2:2016 - Solid mineral fuels - Vocabulary - Part 2: Terms relating to sampling, testing and analysis - is an ISO vocabulary standard that defines the common terms used when sampling, testing and analysing solid mineral fuels (for example, coal and coke). Published as the second edition (2016), the document standardizes language across laboratories, industry and regulation by giving clear definitions, alternative names (with deprecated alternatives noted) and an alphabetical index with numeric cross-references.

Keywords: ISO 1213-2:2016, solid mineral fuels vocabulary, coal sampling standard, coal testing terminology, coke analysis terms.

Key Topics

The standard focuses on terminology rather than prescriptive test methods. Key technical topics and entries include:

• Sampling concepts: bulk sample, channel sample, core sample, continuous sampling, increments and gross samples, constant mass division.
• Analytical bases and moisture terms: as‑received basis, air‑dried basis, air‑drying, total moisture.
• Coal and coke classifications: coal, anthracite, bituminous, brown coal and lignite, coke, blast furnace coke.
• Physical and chemical test vocabulary: ash, ash analysis, ash fusibility and viscosity, calorific value (gross/net at constant volume and pressure), adiabatic calorimeter.
• Mechanical properties and indices: abrasion, abrasion index/value, crush, breakage, bulk density, apparent relative density.
• Quality, uncertainty and measurement terms: accuracy, precision (implicitly contrasted), bias, coefficient of variation.
• Coke performance indicators: CRI (coke reactivity index), CSR (coke strength after reaction), crucible swelling number.
• Miscellaneous: definitions related to sampling devices (chute, cutter), carbominerite, clinkering and other combustion-related terms.

The standard contains definitions, notes to entries, and cross-references; it has no normative references.

Applications and Who Uses It

ISO 1213-2:2016 is a reference vocabulary used by:

• Laboratories and analysts performing coal and coke testing to ensure consistent term usage in reports and certificates.
• Coal producers and traders for contract specifications, sampling protocols and product descriptions.
• Power plants, steelmakers and gasification facilities that rely on standardized terminology for fuel quality, combustion behavior and ash characteristics.
• Standards committees, regulators and auditors to harmonize interpretation of test results and sampling procedures.
• Equipment manufacturers and consultants preparing documentation, user manuals and technical data.

Using this vocabulary reduces ambiguity in technical communication, contract clauses, test reports and regulatory documents.
