Full title and description
ISO 10203:2017 — Iron ores — Determination of calcium — Flame atomic absorption spectrometric method. This International Standard specifies a flame atomic absorption spectrometric (AAS) procedure for determining the mass fraction of calcium in natural iron ores, concentrates and agglomerates (including sinter products).
Abstract
ISO 10203:2017 defines a flame AAS analytical method for measurement of calcium content in iron ore materials. The procedure is applicable to mass fractions of calcium from about 0.010 % up to 8.00 % and covers sample preparation, instrumentation, calibration and quality-control practices needed to obtain reproducible results in that range.

Scope
This standard specifies a flame atomic absorption spectrometric method to determine the calcium mass fraction in iron ores, iron ore concentrates and agglomerates (including sinter products). It is intended for calcium concentrations approximately between 0.010 % and 8.00 % and covers the analytical workflow from sample preparation and digestion to instrumental measurement, calibration and reporting of results.
Key topics and requirements
- Analytical technique: flame atomic absorption spectrometry (AAS).
- Applicable sample types: natural iron ores, concentrates and agglomerates (including sinter).
- Measurement range: approximately 0.010 % to 8.00 % calcium (mass fraction).
- Requirements for sample dissolution/preparation and suitable reagents.
- Calibration procedures, use of standards and blanks, and quality-control checks to ensure reproducibility and accuracy.
- Reporting conventions for results and notes on precision and repeatability specified in the standard text.
Key method and applicability points are taken from the ISO 10203:2017 standard summary.
Typical use and users
Laboratories and quality-control units in mining and mineral processing organizations, metallurgical and materials testing laboratories, commodity testing services, and regulatory or standards bodies use this method to quantify calcium in iron-ore products for product specification, process control and trade/compliance purposes.
Related standards
Other ISO methods for elemental determinations in iron ores and related test methods include standards for sulfur, sodium and potassium determinations (for example ISO documents addressing S, Na and K determination by appropriate procedures). National/adopted versions and related ISO test-method series for iron ores are commonly published alongside ISO 10203.

A: ISO 10203:2017 is an International Standard that specifies a flame atomic absorption spectrometric method for determining the mass fraction of calcium in iron ores and related materials.
Q: What does it cover?
A: It covers the analytical procedure (sample preparation, reagent and instrument requirements, calibration, measurement and result reporting) for calcium determination by flame AAS in iron ore, concentrates and agglomerates, for concentrations roughly between 0.010 % and 8.00 %.
Q: Who typically uses it?
A: Mining and processing QA/QC laboratories, independent testing laboratories, metallurgical labs and others involved in specification, trading or regulation of iron-ore products.
Q: Is it current or superseded?
A: The current edition is ISO 10203:2017 (published March 2017). It replaced the previous ISO 10203:2015 edition and, like all ISO standards, is subject to periodic review (typically every five years) by the responsible technical committee. Users should check the ISO catalogue or national standards body to confirm whether any later revision or confirmation has occurred since 2017.
Q: Is it part of a series?
A: It forms part of the suite of ISO test methods and standards related to iron ores and elemental determinations; related ISO methods address the determination of other elements (for example sulfur, sodium and potassium) in iron ores.
Q: What are the key keywords?
A: iron ores, calcium, flame atomic absorption spectrometry (AAS), analytical method, concentrates, sinter, ICS 73.060.10.
