Full title and description

ISO 10278:1995 — Steel — Determination of manganese content — Inductively coupled plasma atomic emission spectrometric method. This International Standard specifies an ICP‑AES (inductively coupled plasma atomic emission spectrometry) procedure for quantitative determination of manganese in unalloyed steels, including required sample preparation, calibration and instrumental performance checks.

Abstract

Specifies an inductively coupled plasma atomic emission spectrometric method for the determination of the manganese content in unalloyed steels applicable to manganese contents between 0.002 % (m/m) and 1.5 % (m/m). The method covers dissolution of a test portion, optional use of an internal standard, nebulization into an ICP source and measurement of the manganese emission line for quantification.

Scope

ISO 10278:1995 applies to the determination of manganese in unalloyed steels by ICP‑AES and is intended for manganese contents in the range 0.002 % to 1.50 % (mass fraction). The standard defines the principle (dissolution of a test portion in hydrochloric and nitric acids, dilution, optional internal standard addition, nebulization and measurement of the Mn emission line), procedural requirements and quality checks necessary for reliable routine and reference testing.

Key topics and requirements

• Analytical principle: dissolution of the sample, nebulization into an ICP source and measurement of manganese emission (typical primary Mn line given at 257.61 nm in the standard).
• Concentration range and limits: method applicable from 0.002 % to 1.50 % (m/m) Mn with specified calibration and performance checks.
• Internal standard and interference control: optional use of internal standards (e.g., scandium or yttrium) to correct matrix effects and instrument drift.
• Calibration and linearity: multi‑point calibration spanning the working range, blanks and checks for linearity and correlation (high r value expected for routine use).
• Instrument performance and quality assurance: specified instrumental conditions, limits on background equivalent concentration/detection, repeatability/reproducibility guidance and use of ISO referenced laboratory practice (glassware, reagent grade, water quality).

The above topics reflect the procedural and performance elements contained in the published text of ISO 10278:1995.

Typical use and users

Used by metallurgical testing laboratories, steel producers and foundries, third‑party testing and certification bodies, and research laboratories performing routine composition checks or quality control on unalloyed steels. The standard is suitable for laboratory managers and analytical chemists selecting or validating ICP‑AES procedures for manganese determination.

Related standards

ISO 10278 references and is used alongside other ISO standards relevant to chemical analysis and laboratory practice, for example ISO 377 (sampling of steels), ISO 3696 (water for analytical use), ISO 5725 (precision of measurement methods), and routine laboratory glassware standards (ISO 385, ISO 1042, ISO 648). These referenced standards and normative documents are listed in the ISO 10278:1995 text.

FAQ

Q: What is this standard?

A: ISO 10278:1995 is an International Standard that specifies an inductively coupled plasma atomic emission spectrometric (ICP‑AES) method for determining manganese content in unalloyed steels.

Q: What does it cover?

A: It covers sample dissolution and preparation, optional use of internal standards, instrumental measurement (ICP‑AES), calibration and quality checks, and performance characteristics for manganese concentrations between 0.002 % and 1.50 % (m/m).

Q: Who typically uses it?

A: Metallurgical and materials testing laboratories, steel industry quality control labs, certification bodies and analytical chemists responsible for elemental analysis of steels.

Q: Is it current or superseded?

A: The ISO bibliographic record shows ISO 10278:1995 was reviewed and its status confirmed in ISO systematic reviews (most recently confirmed in 2023), so the 1995 edition remains current unless a formal withdrawal or revision is published thereafter. Users should check their national standards body or ISO for any later amendments or replacements.

Q: Is it part of a series?

A: It is produced under ISO/TC 17/SC 1 (methods of determination of chemical composition of steels) and sits alongside other ISO methods for elemental determinations in steels and laboratory practice standards. It is not a multi‑part series under the same number but is one of many ISO documents that define chemical analysis methods for steel constituents.

Q: What are the key keywords?

A: Manganese, Mn, steel, ICP‑AES (ICP‑OES), elemental analysis, calibration, detection limit, unalloyed steel.
