Full title and description

STB BS ISO 3086-2006 (2010) — Iron ores — Experimental methods for checking the bias of sampling. This is the ISO international standard (ISO 3086:2006) adopted as a British Standard (BS ISO 3086:2006) and referenced in some national catalogs with reissue/availability dates in 2010.

Abstract

Specifies experimental procedures to check the bias of sampling of iron ores when sampling is performed in accordance with the sampling methods referenced in ISO 3082 (stopped-belt sampling is used as the reference). The standard sets out experimental designs and statistical procedures to evaluate whether a sampling system or practice introduces a systematic bias.

General information

• Edition / version: ISO edition 4 (ISO 3086:2006; replaces earlier editions including 1998 and 1986).
• Number of pages: ISO listing: 23 pages; national/adopted copies show slight pagination differences (examples: 26 pages in some national catalogs, 30 pages in some distributor listings).

Scope

Provides experimental methods and statistical procedures to determine whether a sampling system for iron ores produces a biased estimate of lot characteristics. The procedures are intended for use when sampling follows the methods in ISO 3082 and use a stopped-belt sampling method as the reference; the focus is on detecting and quantifying systematic bias introduced during sampling and sample preparation.

Key topics and requirements

• Definition of bias in the context of iron-ore sampling and the objective of bias-check experiments.
• Experimental designs for bias-check trials, including reference (stopped-belt) sampling vs. test sampling.
• Statistical methods for analysing experimental data to detect and estimate sampling bias.
• Requirements for test specimens, sample handling and measurement characteristics to ensure valid comparisons.
• Guidance on interpreting results and on reporting bias-check outcomes for quality assurance and contractual purposes.

Typical use and users

Used by mining companies, metallurgical plants, laboratory managers, sampling engineers, quality assurance personnel, and third‑party auditors involved in the sampling and sale/purchase of iron ore. National standards bodies and test laboratories also use the standard when validating sampling systems or preparing national/adopted versions.

Related standards

Commonly referenced standards in the same field include ISO 3082 (sampling and sample preparation procedures for iron ores), ISO 10836 (sampling/sample preparation for physical testing), and related test standards for iron‑ore characteristics (for example ISO 4701 for size distribution). Earlier and related editions of ISO 3086 (1986, 1998) are the historical predecessors.

FAQ

Q: What is this standard?

A: ISO 3086:2006 (adopted as BS ISO 3086:2006) is an international standard that specifies experimental methods to check whether sampling procedures for iron ores introduce a systematic bias.

Q: What does it cover?

A: It covers the design and execution of bias-check experiments, statistical analysis of results, requirements for test specimens and sample handling, and reporting of findings — using a stopped-belt sampling method as the reference and assuming sampling is performed in line with ISO 3082 procedures.

Q: Who typically uses it?

A: Mining and ore-handling organisations, laboratories, QA/QC teams, sampling engineers and contract auditors involved in material transfer, sale/purchase and quality verification of iron ore. Standards organizations and national bodies may adopt or republish the text for local use.

Q: Is it current or superseded?

A: ISO 3086:2006 is the current ISO edition published in 2006 and remains the published edition in ISO records; it replaced earlier editions (1998, 1986). ISO records show the 2006 edition as published and subject to periodic review (ISO record entries show review/confirmation activity through 2020). National adoptions or distributor catalog entries may show reissue or availability dates (e.g., 2010) for their editions. Users should check the issuing body for the absolute latest status before relying on the standard for regulatory or contractual decisions.

Q: Is it part of a series?

A: Yes — ISO 3086 fits within a group of ISO standards on iron ores and sampling (ISO/TC 102/SC 1), which includes ISO 3082 (sampling procedures), ISO 10836 (sampling for physical testing), ISO 4701 (size distribution) and other iron-ore test methods and sampling standards.

Q: What are the key keywords?

A: Iron ores, sampling bias, bias check, sampling methods, stopped-belt sampling, experimental design, statistical analysis, sample preparation, ISO 3086.
