Full title and description
St ISO 5416-2006 — Direct reduced iron — Determination of metallic iron — Bromine‑methanol titrimetric method. This international standard specifies a bromine‑methanol titrimetric analytical procedure for determining the mass fraction of metallic iron in direct reduced iron (DRI) samples.
Abstract
ISO 5416:2006 defines a titrimetric method using bromine in methanol to quantify metallic iron in reduced iron ores (DRI). The method is intended for mass fractions of metallic iron in the approximate range 15 % to 95 % and includes required reagents, apparatus, titration procedure, calculation of results and reporting.

Scope
This standard applies to the determination of the mass fraction of metallic iron in direct reduced iron (DRI) using a bromine‑methanol titrimetric method. It is suitable for samples with metallic iron contents approximately between 15 % and 95 % and covers the analytical procedure, apparatus and reporting of results for laboratory quality control and analytical testing of DRI.
Key topics and requirements
- Principle: oxidation of metallic iron by bromine in methanol and back‑titration to determine metallic iron content.
- Required reagents: preparation and handling of bromine‑methanol solution and titrants; attention to hazards of bromine and methanol.
- Apparatus: standard laboratory glassware (burettes, pipettes, volumetric flasks), analytical balance and suitable titration equipment.
- Sample preparation: guidance for representative sampling and preparation of DRI samples for analysis.
- Analytical procedure: step‑by‑step titration and endpoint determination, blank corrections and calculation of mass fraction of metallic iron.
- Precision and expression of results: calculation examples, reporting format and significant‑figure requirements.
- References and normative cross‑references to relevant laboratory glassware and sampling standards.
Typical use and users
Used by metallurgical laboratories, DRI producers, steelmakers, quality control analysts, independent testing laboratories and research organisations involved in iron production and processing. Typical applications include incoming material inspection, process control, product specification verification and comparative laboratory analyses.
Related standards
ISO 5416:2006 is related to standards covering sampling and sample preparation, laboratory glassware and other analytical methods for iron ores (examples: ISO 10835, ISO 2597‑1, ISO 385, ISO 1042, ISO 648, ISO 2596 and ISO 3696). Several national/adopted versions exist (for example BIS/BS adaptations) that are technically equivalent to ISO 5416:2006.
