Full title and description

Brown coals and lignites — Principles of sampling — Part 1: Sampling for determination of moisture content and for general analysis. This International Standard describes principles and recommended procedures for obtaining representative samples of brown coal and lignite from streams, wagons, barges and stockpiles when samples are taken for moisture determination and general analysis.

Abstract

Part 1 sets out the principles of sampling methods specific to brown coals and lignites (which differ from sampling methods for hard coals), and it explains replicate-sampling procedures and minimum sampling requirements to achieve defined precision and representativeness when determining moisture content and performing general laboratory analysis.

General information

• Status: Withdrawn / no longer current (withdrawal of the International Standard recorded in the ISO lifecycle).
• Publication date: 1 November 1983 (Edition 1, 1983).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 73.040 — Coals.
• Edition / version: Edition 1 (1983).
• Number of pages: 3 (short guidance document / principles statement).

Scope

This part of ISO 5069 establishes the principles of methods to be used for sampling brown coals and lignites from moving and static consignments (belt streams, wagons, barges, stockpiles) specifically when the sample is intended for moisture determination and for general laboratory analysis. It highlights where sampling for brown coals differs from hard-coal sampling and refers to companion documents for sample preparation and related vocabulary.

Key topics and requirements

• Principles for representative sampling of brown coal and lignite from streams, wagons, barges and stockpiles.
• Minimum mass and number of incremental (elementary) samples required to meet stated precision for moisture and general-analysis results.
• Procedures for replicate sampling and conditions under which hand sampling may be acceptable.
• Requirements and recommendations aimed at ensuring that moisture-determination samples are representative at the point of collection.
• Cross-references to related vocabulary and sampling standards (e.g., ISO 1213 and ISO 1988) and to Part 2 (sample preparation).

Typical use and users

Primary users are mineral-fuel and extraction companies, coal preparation and handling facilities, power utilities, testing laboratories, quality assurance and inspection bodies, and national standards organizations. The standard is used for establishing sampling protocols for contractual testing, quality control, and laboratory analysis where moisture content and general composition of brown coal / lignite are required.

Related standards

Key related standards include: ISO 5069-2:1983 — Brown coals and lignites — Principles of sampling — Part 2: Sample preparation for determination of moisture content and for general analysis; ISO 1988 (hard coal — sampling); ISO 1213 (vocabulary for solid mineral fuels). National adoptions and consolidated sampling standards (for example, later national standards that combine ISO 1988 and ISO 5069 parts) may also reference or incorporate these parts.

FAQ

Q: What is this standard?

A: ISO 5069-1:1983 is an ISO International Standard that sets out the principles for sampling brown coals and lignites for the purpose of determining moisture content and for general laboratory analysis.

Q: What does it cover?

A: It covers where and how to take representative samples from moving streams, wagons, barges and stockpiles, minimum incremental-sample masses and frequencies, and replicate-sampling procedures to achieve required precision for moisture and general-analysis results. It is a principles document and references companion parts for sample preparation.

Q: Who typically uses it?

A: Coal producers, handling and preparation plant operators, testing laboratories, power stations, QA/inspection bodies and standards organizations use the guidance when defining sampling protocols for moisture measurement and general coal analysis.

Q: Is it current or superseded?

A: ISO 5069-1:1983 has been withdrawn (the ISO lifecycle shows withdrawal activity in 2017–2018 and the document is no longer current). Users should check for any national adoptions, consolidated national standards or later ISO documents that have replaced or incorporated its content for up-to-date procedures.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 5069 series. Part 2 (ISO 5069-2:1983) covers sample preparation for moisture determination and general analysis; both parts were published in 1983 and later withdrawn.

Q: What are the key keywords?

A: Brown coal, lignite, sampling, sample preparation, moisture determination, replicate sampling, coal analysis, ICS 73.040.
