Overview

EN 15690-2:2009 - "Copper and copper alloys - Determination of iron content - Part 2: Flame atomic absorption spectrometric method (FAAS)" is a CEN standard that specifies a validated FAAS procedure for measuring iron content in copper and copper alloys (castings, unwrought and wrought products). The method is applicable to materials with iron mass fractions from 0.005 % to 5.0 % and covers sample preparation, reagents, instrumentation, calibration and reporting.

Key Topics and Requirements

• Scope & applicability: Designed for copper and copper-alloy products in various forms (cast, unwrought, wrought) with iron between 0.005 % and 5.0 %.
• Principle: Dissolution of the test portion in a hydrochloric/nitric acid mixture, masking interferences with lanthanum(III) chloride, and measurement by flame atomic absorption spectrometry (FAAS) using an iron hollow‑cathode lamp (lines at 248.3 nm or 372.0 nm).
• Sampling: Follow ISO 1811-1 / ISO 1811-2. Test samples should be fine drillings, chips or millings (max 0.5 mm thickness).
• Reagents & materials: Analytical-grade acids (HCl, HNO3, HF - HF requires strict safety controls), lanthanum chloride masking solution, iron and copper standard solutions for calibration.
• Sample preparation: Acid dissolution, filtration if silicon is present, optional HF treatment and ashing to remove silicon residues, then appropriate dilution depending on expected iron level.
• Calibration & matrix matching: Calibration curves prepared over concentration ranges matching the three iron intervals; copper base solutions are added to calibration standards to match matrix effects of copper in samples.
• Quality control: Blank determinations, check tests using reference or synthetic samples, duplicate analyses, and instrument adjustment procedures are specified.
• Apparatus: FAAS with an air/acetylene burner and iron hollow-cathode lamp; follow manufacturer instructions for burner configuration and gas flows.
• Reporting and precision: The standard includes requirements for expression of results, precision data and mandatory test report items.

Applications and Users

• Practical for metallurgical quality control, acceptance testing, and compositional analysis in:
  • Copper foundries and alloy producers
  • Independent materials testing and inspection laboratories
  • R&D and failure analysis labs working with copper alloys
  • Procurement and compliance teams verifying material specifications
• Useful where reliable, routine determination of iron in copper matrices is required (production control, product certification, supplier verification).

Transfer the test portion (7.1.1) into a 250 ml beaker. Add 10 ml of hydrochloric acid (4.2) and 10 ml of the nitric acid solution (4.4). Cover with a watch glass and heat gently until the test portion is completely dissolved. Allow to cool. If undissolved matter remains, indicating the presence of silicon, filter the solution. Place the filter paper and contained salts in a platinum crucible and ash, taking care that the filter does not flame. Calcine at about 550 °C. Cool and add 5 ml of hydrofluoric acid (4.5) and five drops of nitric acid (4.3). Evaporate to dryness and calcine again for several minutes at about 700 °C to completely volatilize the silicon. Cool, and then dissolve the residue with the least possible volume of nitric acid solution (4.4). Filter, if necessary, and add this filtrate quantitatively to the original filtrate. 7.1.3 Iron mass fractions between 0,005 %
