Overview

EN 15622:2010 is a European Standard published by CEN that specifies a method for determining the lead content in copper and copper alloys using flame atomic absorption spectrometry (FAAS). This standard is applicable to unwrought, wrought, and cast copper products with lead mass fractions ranging from 0.01% to 5.0%. The procedure provides a reliable analytical technique that helps ensure quality control and compliance in the copper industry.

Key Topics

• Scope and Applicability: Covers determination of lead in various copper forms, including unwrought, wrought, and cast products. Suitable for lead concentrations between 0.01% and 5%.
• Analytical Principle: The method involves dissolving the test portion in a fluoroboric-nitric acid solution followed by aspirating the test solution into an air-acetylene flame. The lead content is then measured by atomic absorption at 217.0 nm, using a lead hollow-cathode lamp.
• Sampling: Samples are prepared as fine drillings or chips with a maximum thickness of 0.5 mm, in accordance with ISO 1811 standards for copper alloy sampling.
• Reagents: Includes the use of nitric acid, hydrofluoric acid, boric acid, and specially prepared fluoroboric-nitric acid mixtures. Lead stock and calibration solutions are precisely formulated for accurate quantification.
• Apparatus: Requires an atomic absorption spectrometer equipped with an air/acetylene burner and a lead hollow-cathode lamp, alongside specialized volumetric flasks and beakers made of materials resistant to acid attack (PTFE, polyethylene, or polypropylene).
• Calibration and Measurement: Calibration solutions are prepared with copper content similar to that of the test solutions to negate chemical interaction effects. Multiple calibration ranges are defined depending on the expected lead concentration. The calibration curve is constructed from absorbance data for accurate determination.
• Precision and Quality Control: The standard includes procedures for blank and check tests to ensure proper instrument calibration and accurate results.

Applications

• Industrial Quality Control: EN 15622:2010 allows manufacturers and laboratories to accurately determine lead content in copper alloys, essential for maintaining product specifications and safety standards.
• Regulatory Compliance: Facilitates compliance with environmental and material regulations by providing a validated, standardized method for lead quantification in metal alloys.
• Material Certification: Supports the certification and traceability of copper alloy materials by providing precise analytical data on lead concentration.
• Research and Development: Assists R&D laboratories in assessing the effects of varying lead contents in alloy compositions for improved material properties.

Related Standards

• ISO 1811-1: Copper and copper alloys – Selection and preparation of samples for chemical analysis – Part 1: Sampling of cast unwrought products.
• ISO 1811-2: Copper and copper alloys – Selection and preparation of samples for chemical analysis – Part 2: Sampling of wrought products and castings.
• Additional standards on atomic absorption spectrometry and spectral analysis techniques may support this method.

By adhering to EN 15622:2010, laboratories ensure consistent, accurate measurement of lead content in copper and copper alloy products, enhancing quality assurance and supporting international trade standards. This method’s reliance on FAAS provides a robust and widely accessible technique for laboratories globally, contributing to material integrity and regulatory adherence in the copper manufacturing sector.
