Full title and description

ISO 10836:1994 — Iron ores — Method of sampling and sample preparation for physical testing. This International Standard specifies procedures and requirements for obtaining representative samples of iron ores and for preparing those samples for physical tests referenced in related ISO standards.

Abstract

The testing covered refers to the physical test methods specified in the relevant international standards (ISO 3271, ISO 3852, ISO 4695, ISO 4696, ISO 4698, ISO 4700, ISO 7215, ISO 7992). With respect to the bulk density test, only method 1 in ISO 3852, using a small container for iron ores having a nominal top size of 40 mm or smaller, falls within the scope.

Scope

ISO 10836:1994 defines methods for sampling and preparing samples of iron ores for physical testing. It is limited to the sampling and sample-preparation aspects needed for the physical test methods cited (e.g., particle size distribution, mechanical tests and specified bulk density method). For bulk density the standard only includes method 1 of ISO 3852, intended for ores with nominal top size ≤ 40 mm. The standard addresses representative increment selection, splitting, reduction and preparation of test portions to meet the requirements of the referenced physical test standards.

Key topics and requirements

• Principles for obtaining representative samples from lots (systematic, mass‑ or time‑basis sampling and stratified sampling where needed).
• Design, installation and operation requirements for mechanical sampling systems and guidance for manual sampling where applicable.
• Increment mass, number of increments and rules for gross, partial and test sample construction to achieve stated precision levels.
• Sample splitting and reduction procedures to prepare test samples and test portions while avoiding bias.
• Storage and handling provisions (e.g., moisture samples) to prevent alteration prior to testing.
• Scope of physical tests to be supported (references to ISO 3271, 3852, 4695, 4696, 4698, 4700, 7215, 7992) and the special note on bulk density (ISO 3852 method 1 for nominal top size ≤ 40 mm).

Typical use and users

Used by mining and beneficiation operations, sampling-system designers and suppliers, independent testing and assay laboratories, port and shipping sampling personnel, quality assurance teams and purchasers/sellers involved in iron ore trading. Typical tasks include establishing sampling protocols, verifying sampling-system performance, preparing test samples for physical property determination, and ensuring legally and commercially defensible sample representativity.

Related standards

Replaced by and consolidated into the ISO 3082 series (ISO 3082:2009 and later editions, ISO 3082:2017). Other directly referenced physical test standards include ISO 3271, ISO 3852, ISO 4695, ISO 4696, ISO 4698, ISO 4700, ISO 7215 and ISO 7992. The technical work was produced under ISO/TC 102/SC 1 (iron ores).

FAQ

Q: What is this standard?

A: ISO 10836:1994 is an ISO International Standard that provided methods for sampling iron ores and preparing samples for physical testing.

Q: What does it cover?

A: It covers sampling procedures (increment selection, systematic/mass/time‑basis sampling, stratified sampling where needed), sample reduction and preparation for the physical tests referenced (including a specific provision for bulk density using ISO 3852 method 1 for ores ≤ 40 mm nominal top size).

Q: Who typically uses it?

A: Mining and processing companies, sampling-system manufacturers, testing laboratories, QA/QC personnel, and commercial/port sampling teams involved in iron ore quality assessment and trade.

Q: Is it current or superseded?

A: ISO 10836:1994 has been withdrawn. Its content was incorporated into later ISO 3082 editions (ISO 3082:2009 and subsequent revisions, e.g., ISO 3082:2017). Users should refer to the current ISO 3082 edition for up‑to‑date sampling and sample‑preparation requirements.

Q: Is it part of a series?

A: It is related to and intended to be used with a suite of test standards for iron ores (ISO 3271, 3852, 4695, 4696, 4698, 4700, 7215, 7992) and with the broader ISO 3082 sampling standards for iron ores.

Q: What are the key keywords?

A: Iron ores, sampling, sample preparation, representativity, bulk density, physical testing, ISO 3082.
