Full title and description

ISO 2596:1984 — Iron ores — Determination of hygroscopic moisture in analytical samples — Gravimetric and Karl Fischer methods. This edition specifies laboratory procedures for determining the hygroscopic (adsorbed) moisture content of small analytical samples of iron ores using gravimetric drying and Karl Fischer titration techniques.

Abstract

The 1984 (3rd) edition of ISO 2596 defines two laboratory methods for measuring hygroscopic moisture in analytical samples of iron ores: a gravimetric (oven-drying) method and a Karl Fischer (volumetric or coulometric) method. The procedures are intended to provide moisture values needed when reporting constituent results on a dry basis for certain ore types. This edition has since been withdrawn and later revised.

Scope

ISO 2596:1984 specifies two test methods for determining hygroscopic moisture in analytical samples of iron ores. The methods are applicable where moisture determinations are required to calculate analytical results on a dried-sample basis for certain ore types (for example, processed ores containing metallic iron, ores with elevated sulfur, or ores with combined water). The later 2006 revision expanded and clarified available methods (adding mass-loss and other Karl Fischer variants).

Key topics and requirements

• Definition of hygroscopic moisture for analytical samples of iron ores.
• Gravimetric (oven-drying) method: sample preparation, drying conditions, cooling and weighing procedures, calculation of moisture loss.
• Karl Fischer method (volumetric/coulometric): reagents, titration procedure, sample handling to avoid evaporation or uptake, calculation of water content.
• Guidance on applicability and limits of the methods (typical hygroscopic moisture concentration ranges used in later revisions).
• Requirements for laboratory equipment, calibration, and reporting of results to allow conversion of analytical constituents to a dry basis.

Typical use and users

Used by analytical laboratories in mining and mineral processing, quality control and commercial assay laboratories, research laboratories working with iron ores, and standards bodies establishing test procedures. Typical users apply the methods to determine moisture corrections when reporting chemical analyses of iron ores.

Related standards

ISO 2596:1984 was later revised (ISO 2596:1994 — also withdrawn) and subsequently replaced by ISO 2596:2006, which expanded the methods to include gravimetric, Karl Fischer (volumetric and coulometric) and a mass-loss method. Users should consult the 2006 edition for the current validated procedures.

FAQ

Q: What is this standard?

A: ISO 2596:1984 is an International Standard that specified laboratory procedures for the determination of hygroscopic moisture in analytical samples of iron ores using gravimetric and Karl Fischer methods.

Q: What does it cover?

A: It covers two laboratory test methods (gravimetric drying and Karl Fischer titration) including sample handling, test conditions, calculations and reporting conventions for hygroscopic moisture in small analytical ore samples. Later versions expanded the scope to additional methods.

Q: Who typically uses it?

A: Mining company laboratories, commercial assay and QA/QC labs, research institutions analyzing iron ores, and standards organizations referencing moisture-determination procedures. These users apply the methods when constituents must be reported on a dry basis.

Q: Is it current or superseded?

A: ISO 2596:1984 is withdrawn. It was revised (ISO 2596:1994, withdrawn) and superseded by ISO 2596:2006, which is the published (current) edition providing the consolidated methods. Users requiring up-to-date procedures should refer to ISO 2596:2006.

Q: Is it part of a series?

A: ISO 2596 is a standalone standard addressing moisture determination in iron ores, but it sits within the broader set of ISO deliverables and test methods for iron ores and analytical procedures developed by ISO/TC 102/SC 2. Later and related standards address lot moisture, other analytical determinations, and test-method interoperability.

Q: What are the key keywords?

A: Hygroscopic moisture; iron ores; gravimetric; Karl Fischer; moisture determination; analytical sample; laboratory method; moisture correction; ISO 2596.
