Overview
SIST EN 10071:2013 is a European Standard established by CEN for the chemical analysis of ferrous materials, specifically focusing on the determination of manganese content in steels and irons using an electrometric titration method. This standard applies to unalloyed, low alloy, and alloyed steels, as well as irons containing manganese at or above 0.5% by mass. It provides a reliable and precise method to assess manganese levels, a crucial element influencing the mechanical properties and quality of ferrous products.
Key Topics
Scope and Application
The standard targets manganese analysis in ferrous metals with manganese contents ≥ 0.5%, useful across different steel grades and iron types.Principle of the Method
- Dissolution of the sample in acids followed by partial neutralization
- Precipitation of interfering cations using zinc oxide
- Titration of Mn(II) with potassium permanganate in a pyrophosphoric medium at pH ~6.5
- Endpoint detection via electrometric measurement ensures accuracy and reproducibility
Reagents & Apparatus
- Detailed requirements for reagents including purified water, acids, zinc oxide, sodium hydrogen carbonate, and standardized potassium permanganate solutions
- Equipment such as magnetic stirrers, potentiometers, pH meters, and Class A calibrated volumetric glassware
Sampling and Test Procedures
- Sampling following EN ISO 14284 or equivalent
- Specific dissolution protocols for different types of steels and irons
- Precise pH adjustment and filtration steps to avoid manganese loss
- Titration volumes adjusted according to manganese concentration for optimum accuracy
Result Expression and Reporting
- Calculation formula for manganese mass fraction based on titration data
- Comprehensive test report requirements including sample details, test results, and any deviations or observations
Applications
Quality Control in Steel Production
Enables manufacturers to ensure compliance with product specifications by accurately quantifying manganese content, a key factor impacting steel hardness, toughness, and ductility.Metallurgical Laboratories
Standardized titration method supports consistent chemical analysis across labs involved in research and development or certification testing of ferrous materials.Regulatory Compliance and Material Certification
Provides a recognized methodology for manganese determination that harmonizes testing approaches across European countries, facilitating trade and compliance with international quality standards.Failure Analysis and Material Verification
Helps in tracing manganese-related anomalies in steel and iron components, critical for forensic investigations of material failures.
