Full title and description

ISO 1018:2023 — Coal — Determination of moisture‑holding capacity. This International Standard specifies a reference method for assessing the moisture‑holding (equilibrium moisture) characteristics of coal and cross‑references the equivalent ASTM procedure used for laboratory determination.

Abstract

The document provides a short reference method for determining the moisture‑holding capacity of coal; it makes explicit reference to ASTM D1412 as the method for determining equilibrium moisture under controlled relative humidity and temperature conditions.

Scope

ISO 1018:2023 covers the determination of coal moisture‑holding capacity (equilibrium moisture). Rather than defining a wholly new laboratory procedure, the standard explicitly references ASTM D1412 as the method to be used for measuring equilibrium moisture (typically determined at about 96–97 % relative humidity and 30 °C in the ASTM procedure). The standard is intended for application to coal quality testing and reporting where equilibrium moisture is required.

Key topics and requirements

• Reference to ASTM D1412 as the measurement procedure for equilibrium moisture of coal.
• Definition and reporting of moisture‑holding capacity ( equilibrium moisture ) for coal samples.
• Applicability to coal quality control, commercial reporting and laboratory testing where equilibrium moisture values are required.
• Short-form International Standard intended as a cross‑reference to an established ASTM test method rather than a lengthy standalone method description.

Typical use and users

Used by coal testing laboratories, mine quality control teams, commodity traders, fuel analysts and researchers who need to determine or report the equilibrium moisture (moisture‑holding capacity) of coal for quality assessment, contract verification and process control. National standards bodies and testing organizations also use the standard as the ISO reference for this measurement.

Related standards

ISO 1018:2023 replaces earlier editions of ISO 1018 (including ISO 1018:2019 and ISO 1018:1975). The standard explicitly references ASTM D1412 (ASTM D1412/D1412M) for the laboratory procedure. It is maintained under ISO/TC 27/SC 5 (coal and coke technical committee).
