This document specifies a spectrophotometric method for the determination of manganese in steel and cast iron. The method is applicable to manganese contents between 0,001 % (mass fraction) and 4,0 % (mass fraction).

Abstract

Overview

ISO 629:2026 specifies an internationally recognized spectrophotometric method for the determination of manganese content in . Developed by the International Organization for Standardization (ISO), this standard is applicable to manganese mass fractions ranging from . The methodology is designed to provide precise, reliable results for quality control and chemical analysis in metallurgy and manufacturing sectors.

Key Topics

Scope of Applicability
- Suitable for both steel and cast iron samples.
- Covers a broad range of manganese concentrations, supporting diverse industrial needs.
Spectrophotometric Method
- Involves dissolving the sample in a mixture of acids and forming a colored compound for photometric analysis.
- Measurement is conducted at a wavelength of approximately 545 nm for optimal sensitivity.
Sample Preparation and Calibration
- Detailed steps for preparing test portions based on presumed manganese content.
- Blank tests and the establishment of calibration curves ensure accurate quantification.
Lab Equipment and Reagents
- Use of class A volumetric glassware as per ISO standards.
- Highly pure reagents and water, following ISO 3696 specifications, are critical for valid results.
Reporting Requirements
- Clear instructions for documenting analysis results, methods, and any deviations, supporting traceability and compliance.

Applications

Metallurgical Quality Control
- Ensures the manganese content in steel and cast iron is within required specifications, essential for product durability and performance.
- Used in steel production plants, foundries, and metal fabrication facilities for routine process monitoring.
Research and Development
- Assists material scientists and laboratory analysts in evaluating the composition of new alloys and materials.
Regulatory Compliance
- Enables organizations to meet international requirements for chemical composition in metallurgical products.
- Supports audits and certification processes by providing standardized testing protocols.
Supply Chain Quality Assurance
- Adopted by suppliers and manufacturers to verify material quality before use or delivery, reducing risk of defects and non-conformance.
