ISO 4296-1-1984 PDF

Full title and description

ISO 4296-1:1984 — Manganese ores — Sampling — Part 1: Increment sampling. Specifies standardized methods for taking representative increment samples of manganese ores at dispatch and acceptance points for the purpose of determining chemical composition and moisture content; applicable to manual and mechanical sampling with details (for example the hammer-and-shovel method) provided in an annex.

Abstract

This part of ISO 4296 defines procedures for increment sampling of manganese ores to obtain representative samples for chemical analysis and moisture determination. It covers definitions (increment, subsample, gross sample), sampling equipment and procedures for both manual and mechanical methods, and gives practical details for sampling lumps larger than 100 mm.

General information

• Status: Published — International Standard (confirmed on review; remains current).
• Publication date: 1984-05 (first edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 73.060.20 (Manganese ores).
• Edition / version: Edition 1 (1984).
• Number of pages: 11.

Scope

Applies to all manganese ores (natural or processed) at points of dispatch and acceptance. The standard prescribes how to take representative increment samples and how to form subsamples and gross samples suitable for determining chemical composition and moisture content. It is intended for use with both manual and mechanical sampling systems and includes an annex describing the hammer-and-shovel technique for coarse lump ores.

Key topics and requirements

• Definitions: increment, subsample, gross sample and related terms used for sampling chains.
• Requirements for sampling equipment and recommended design/handling to avoid bias.
• Procedures for taking increments from consignments (manual and mechanical methods).
• Instructions for formation of subsamples, composite samples and gross samples to ensure representativeness.
• Guidance on sampling ores with large lumps (hammer-and-shovel method), and on handling wet or sticky material.
• Requirements to preserve sample integrity for subsequent moisture and chemical analysis (lab submission and labeling practices).

Typical use and users

Used by mining and ore-processing companies, sampling technicians, laboratory personnel, trading and commodity inspectors, quality-control teams, and regulatory bodies involved in acceptance testing, shipment verification and contract compliance for manganese ore consignments.

Related standards

ISO 4296 is a multi-part series. Part 2 (ISO 4296-2:1983) covers preparation of samples (riffle dividers, grinding and splitting procedures). Other nearby ISO standards referenced in practice include methods for moisture determination and analytical procedures for manganese content (for example ISO 4299 and ISO 4298 as separate related standards).

FAQ

Q: What is this standard?

A: ISO 4296-1:1984 is the International Standard that specifies increment-sampling procedures for manganese ores intended for chemical and moisture analysis at dispatch and acceptance points.

Q: What does it cover?

A: It covers definitions, sampling equipment and procedures for taking increments, forming subsamples and gross samples, and handling coarse lumps (hammer-and-shovel method). It is focused on obtaining representative samples for chemical composition and moisture determination.

Q: Who typically uses it?

A: Mining and ore-processing operators, laboratory analysts, shippers and receivers of manganese ore consignments, quality assurance teams, commodity inspectors and regulatory bodies involved in trade and contract compliance.

Q: Is it current or superseded?

A: The published 1984 edition of ISO 4296-1 has been reviewed and confirmed (ISO review lifecycle) and remains the current edition as of the most recent ISO confirmation. Check with your national standards body or ISO for the latest administrative status before purchase or formal citation.

Q: Is it part of a series?

A: Yes — ISO 4296 is multi-part. Part 1 covers increment sampling (this document) and Part 2 covers preparation of samples; other closely related ISO documents address moisture determination and analytical methods for manganese.
