Overview

EN 15025:2010 is a European Standard developed by CEN that defines a precise flame atomic absorption spectrometric method (FAAS) for the determination of magnesium content in copper and copper alloys. This method applies to various forms including unwrought, wrought, and cast copper products. The standard specifically targets materials with magnesium mass fractions ranging from 0.001% to 0.20%.

This standard provides a reliable and reproducible analytical technique that ensures quality control and compliance in industries where copper alloys are used, enhancing the accuracy of magnesium analysis through atomic absorption spectrometry.

Key Topics

• Scope and Application
  EN 15025:2010 is applicable to copper and copper-alloy products such as sheets, rods, castings, and other forms in both industrial and research contexts. It enables precise quantification of magnesium within defined concentration limits.

• Analytical Principle
  The method dissolves the copper alloy test sample in a hydrochloric-nitric acid mixture. After dilution, the solution is introduced into an air/acetylene flame of an atomic absorption spectrometer. Magnesium concentration is measured by the absorption of light at 285.2 nm emitted by a magnesium hollow-cathode lamp.

• Reagents and Solutions
  The standard lists high-purity reagents including hydrochloric acid, nitric acid, and lanthanum chloride solution to minimize interference. Prepared magnesium standard solutions and copper base solutions are used for calibration and accurate measurement.

• Sampling and Sample Preparation
  Sampling follows ISO 1811 standards, with samples taken as fine drillings, chips, or millings. Test portions are precisely weighed and dissolved under controlled conditions to ensure complete digestion of the sample.

• Calibration and Measurement
  Calibration solutions mimic the matrix of the test solutions in terms of copper and acidity to compensate for chemical interferences. The calibration curve is prepared using known concentrations of magnesium, and results are determined through direct absorbance measurement or bracketing.

• Precision and Quality Control
  The method requires duplicate independent analyses and includes procedural steps for blank tests and check tests with reference materials to ascertain instrument accuracy and method reliability.

Applications

• Quality Control in Copper Alloy Manufacturing
  EN 15025:2010 provides manufacturers with an accurate and standardized technique to verify magnesium content, crucial in tailoring alloy properties and ensuring conformity with product specifications.

• Materials Testing and Compliance
  Laboratories testing copper and its alloys, especially in automotive, electrical, and construction industries, rely on this standard to assure compliance with regulations and optimize material performance.

• Research and Development
  Scientists developing novel copper alloys benefit from this method to accurately correlate magnesium content with mechanical and chemical properties.

• Regulatory and Certification Bodies
  The method supports regulatory compliance by offering a harmonized analytical approach adopted across Europe, facilitating mutual recognition among member states.

Related Standards

• ISO 1811-1 & ISO 1811-2 – These standards specify sampling methods for cast and wrought copper products, ensuring that test specimens for EN 15025:2010 are representative and consistent.

• CEN/TS 15025:2006 – The predecessor technical specification that EN 15025:2010 supersedes, with updated and refined procedures to improve accuracy and usability.

• Other CEN Standards on Copper Alloys – Include methods for determination of other alloying elements or physical properties that complement the analysis of magnesium under this standard.

Summary

EN 15025:2010 is an essential standard for laboratories and industries requiring precise determination of magnesium in copper and copper alloys. By leveraging the flame atomic absorption spectrometric method, it ensures analytical accuracy, repeatability, and harmonization across Europe. Its application enhances the control of material quality, supports compliance with industry requirements, and facilitates confident decision-making in copper alloy processing and use.
