Full title and description

ISO 1017:2006 — Brown coals and lignites — Determination of acetone-soluble material ("resinous substance") in the benzene-soluble extract. The standard specifies a laboratory method for determining the mass fraction of acetone‑soluble material (the "resinous substance") in the benzene‑soluble extract obtained from brown coals and lignites, including sample preparation, extraction, drying and calculation procedures to make results comparable between laboratories.

Abstract

This document defines a quantitative test method in which the benzene‑soluble extract of a brown coal or lignite sample is treated with acetone at controlled temperature, the acetone‑soluble fraction separated, dried and weighed; the mass fraction of acetone‑soluble material is then calculated relative to the benzene‑soluble extract taken. The procedure includes details on apparatus, extraction repetitions, temperature control, drying to constant mass and calculation of results (reporting as the mean of duplicate determinations).

Scope

ISO 1017:2006 applies to laboratory determinations of the mass fraction of acetone‑soluble material present in the benzene‑soluble extract of brown coals and lignites. It is intended for analytical laboratories performing routine quality and research testing of brown coals and lignites and assumes that the benzene‑soluble extract has been prepared in accordance with the referenced methods (see related standards). The method specifies controlled extraction temperature (to preserve selectivity), the number of extractions, separation (centrifugation/filtration), solvent evaporation and drying to constant mass, and the calculation method including reporting precision.

Key topics and requirements

• Definition of the analyte: acetone‑soluble material (resinous substance) within the benzene‑soluble extract of brown coal/lignite.
• Reference to preparation of the benzene‑soluble extract (see ISO 975 or equivalent method).
• Specified extraction conditions (acetone extraction at controlled temperature, typically 18–22 °C, with repeated extractions until clear).
• Apparatus and consumables: centrifuge or filtration equipment, evaporating dishes, drying ovens / vacuum ovens, sieves and balance with suitable accuracy.
• Drying and weighing procedures: solvent removal and drying to constant mass, temperature specification for drying and mass-stability criteria.
• Calculation and reporting: mass fraction calculation relative to benzene‑soluble extract taken; reporting as mean of duplicate determinations with stated repeatability/reproducibility limits where provided.

Typical use and users

Used by analytical laboratories in coal research, fuel quality control, mining laboratories, utilities, coke and briquette manufacturers, and regulatory/testing bodies that assess brown coal and lignite properties. Typical applications include characterizing resinous fractions for processing behaviour, quality grading and research into coal constituents.

Related standards

Closely related to ISO 975 (methods for obtaining the benzene‑soluble extract / yield of benzene‑soluble extract) and other ISO/TC 27/SC 5 methods for brown coals and lignites. ISO 1017:2006 replaced earlier ISO 1017 editions (for example ISO 1017:1985) and itself has been revised by ISO 1017:2025. For benzene‑extract yield determination, see the later ISO 975 series (e.g., ISO 975:2021).

FAQ

Q: What is this standard?

A: ISO 1017:2006 is an ISO International Standard that specifies a laboratory test method for determining the mass fraction of acetone‑soluble material (called the "resinous substance") in the benzene‑soluble extract of brown coals and lignites.

Q: What does it cover?

A: It covers sample handling of the benzene‑soluble extract, controlled acetone extraction conditions, separation (centrifuge/filtration), solvent removal, drying to constant mass, calculation of the mass fraction and reporting conventions (including precision requirements). It does not cover preparation of the original benzene extract in detail — that is covered by related standards such as ISO 975.

Q: Who typically uses it?

A: Coal testing laboratories, research institutions, mining company laboratories, utilities and industrial users who need to characterize the resinous fraction of brown coal and lignite for quality control, processing or research purposes.

Q: Is it current or superseded?

A: ISO 1017:2006 has been withdrawn and superseded by a newer edition, ISO 1017:2025 (published/released in 2025). Users should consult ISO 1017:2025 for the current normative text and any updated requirements.

Q: Is it part of a series?

A: It is part of ISO/TC 27/SC 5's collection of methods of analysis for brown coals and lignites; it should be used alongside other related standards such as ISO 975 (benzene‑soluble extract yield) and other ISO methods for coal analysis.

Q: What are the key keywords?

A: Brown coal, lignite, acetone‑soluble, resinous substance, benzene‑soluble extract, coal analysis, extraction, ISO 1017.
