Full title and description

St ISO 22961-2008 — Titanium and titanium alloys — Determination of iron — Atomic absorption spectrometry. This International Standard specifies an atomic absorption spectrometric method for the determination of the mass fraction of iron in titanium and titanium alloys.

Abstract

ISO 22961:2008 defines a standardized atomic absorption spectrometry (AAS) procedure for measuring iron content in titanium and titanium alloys. The method covers determination of iron in the approximate mass fraction range 0.005 % to 2.0 %, and includes requirements for sample preparation, calibration and measurement using AAS.

Scope

This standard specifies an atomic absorption spectrometric method for determination of the mass fraction of iron in titanium and titanium alloys. It is applicable to titanium materials having iron contents in the mass fraction range from 0,005 % to 2,0 %. The document focuses on the analytical procedure (instrumental parameters, calibration, reagents and general laboratory practice) required to obtain reproducible AAS results for iron in these metallic matrices.

Key topics and requirements

• Analytical technique: flame or graphite-furnace atomic absorption spectrometry (AAS) as specified for iron determination.
• Applicability: titanium and titanium-based alloys with iron mass fraction between 0.005 % and 2.0 %.
• Sample preparation: dissolution/digestion procedures appropriate for titanium matrices to bring iron into solution for AAS measurement.
• Calibration and standards: preparation of calibration solutions and use of appropriate reference materials and blanks.
• Instrumental settings and performance checks: recommended wavelengths, background correction and sensitivity checks specific to iron AAS.
• Quality control: repeatability, detection/quantitation considerations and routine verification using reference materials.
• Normative references: laboratory glassware and water quality standards referenced by the method (e.g., ISO 1042, ISO 3696, ISO 384 and related documents).

Typical use and users

Used primarily by metallurgical and materials testing laboratories, quality control departments in titanium producers and fabricators (including aerospace, medical implants, and specialty engineering sectors), and third‑party conformity and certification labs that must verify iron content in titanium and titanium alloys to meet material specifications and regulatory or contractual requirements.

Related standards

Closely related documents include ISO 22960:2008 (determination of iron by molecular absorption spectrometry using 1,10‑phenanthroline) and several laboratory reference standards cited as normative references (ISO 1042, ISO 3696, ISO 384). National adoptions such as BS ISO 22961:2008 are identical in technical content.
