Overview - EN 15616:2012 (FAAS) for cadmium in copper alloys

EN 15616:2012 is a CEN European Standard that specifies a flame atomic absorption spectrometric (FAAS) method for determining cadmium (Cd) mass fraction in copper and copper alloys (unwrought, wrought and cast). The method covers products with cadmium mass fractions from 0.0005 % to 0.1 % and provides a validated, reproducible laboratory procedure for routine quality control and compliance testing.

Key topics and technical requirements

• Scope & materials: Applicable to unwrought, wrought and cast copper alloys; sampling referenced to ISO 1811‑1 / ISO 1811‑2.
• Analytical principle: Dissolve a weighed test portion in hydrochloric and nitric acids, dilute, aspirate into an air/acetylene flame, and measure Cd absorption at 228.8 nm using a cadmium hollow‑cathode lamp.
• Reagents & standards: Requirements for analytical‑grade reagents; prepared Cd stock (1.0 g/L) and Cd standard (0.005 g/L) solutions; copper base solutions (50 g/L and 5 g/L Cu) used to match matrix effects.
• Sample preparation: Fine drillings/chips/millings (max 0.5 mm thickness); specific dissolution and dilution steps vary by expected Cd level (separate procedures for 0.0005–0.01 % and 0.01–0.10 % ranges).
• Calibration & measurement:
  • Calibration solutions prepared so copper, chloride, nitrate and acidity match test solutions.
  • Use a multi‑point calibration curve or a bracketing method (±10 % around estimate).
  • Perform blank and check tests with reference materials or synthetic samples.
• Expression of results: Cadmium mass fraction calculated from measured concentration, sample mass and final solution volume; formulas and calculation examples are provided.
• Precision and validation: Interlaboratory validation across seven labs with reported repeatability (r) and reproducibility (R) values for multiple Cd levels; example results included in the standard.

Practical applications and users

This standard is intended for:

• Metallurgical and materials testing laboratories performing composition control of copper alloys.
• Manufacturers and quality control teams in copper product and component production.
• Regulatory and inspection bodies verifying compliance with material specifications and cadmium limits.
• Research and development labs developing or verifying alloy chemistries.

Typical applications include incoming material inspection, final product certification, failure analysis where Cd contamination is a concern, and routine monitoring to meet safety or alloy specification requirements.
