Overview
EN 15605:2010 - published by CEN - specifies six inductively coupled plasma optical emission spectrometry (ICP-OES / ICP emission spectrometry) methods (Methods A–F) for determining alloying elements and impurities in copper and copper alloys (unwrought, wrought and cast products). The standard defines sample dissolution, calibration and measurement practice for reliable chemical analysis and includes an informative Annex B covering a complementary method for copper‑tin‑lead alloys (precision for some elements is limited).
Key topics and technical requirements
- Analytical principle: Acid dissolution of a test portion (hydrochloric and nitric acids), addition of an internal reference element, nebulization of the sample solution into an ICP plasma and measurement of emission intensities.
- Methods covered:
- Method A - Coppers
- Method B - Copper‑zinc alloys
- Method C - Copper‑tin alloys
- Method D - Copper‑aluminium alloys
- Method E - Copper‑beryllium alloys
- Method F - Copper‑nickel alloys
- Elemental ranges: The standard lists applicable elements and mass‑fraction ranges in Tables 1–6 (examples: Zn in brass ~10–42 %, Sn in bronzes ~3–16 %, Be in Cu‑Be alloys ~0.08–4 %, Ni in Cu‑Ni ~7–35 %, Al in Cu‑Al ~6–14 %). NOTE: ranges can be extended to lower mass fractions with appropriate checks.
- Quality and performance: Requires analytical‑grade reagents, defined calibration procedures, use of an internal standard and instrument performance checks (Annex A suggests OES performance criteria). Precision criteria are specified per method; Method G (Cu‑Sn‑Pb, Annex B) is informative because precision for some elements (e.g., Zn, P) is not fully satisfactory.
- Normative references: Includes ISO 1811‑1 and ISO 1811‑2 for sampling and sample preparation.
Applications and users
- Who uses it: Metallurgical laboratories, commercial testing labs, OEMs and manufacturers of copper alloys, quality control and inspection teams, materials engineers, R&D and failure analysis specialists.
- Practical uses:
- Chemical composition certification and batch release of copper alloys
- Incoming material inspection and supplier qualification
- Process control in alloy production and casting
- Material qualification for electrical, marine, automotive and aerospace components
- Trace impurity analysis for compliance and material specifications
- Benefits: Provides standardized ICP‑OES procedures to improve comparability of results, ensure traceable alloy analysis and support regulatory/contractual acceptance.

Prepare the software for the measurement of the intensity of each analytical line and for the calculation of the corresponding mean value and relative standard deviation.

A simultaneous spectrometer shall be available for measurements using yttrium as "internal standard" (ratio mode). For phosphorus and arsenic determination, use "absolute intensity" taking into account that "Gaussian" meas-uring mode may also be recommended. For each calibration solution (including the "drift survey" solution) at least three integrations are necessary in order to calculate the mean ratioed intensities (mean absolute intensity for phosphorus and arsenic). In order to control the drift of the spectrometer, analyse the "drift survey" solution (see Table 10 and 7.2.3.1.3) at least once for every five test portion solutions.

The European Standard EN 15605:2010 describes six methods (A to F) using inductively coupled plasma emission spectrometry to determine alloying elements and impurities in copper and copper alloys. These methods can be applied to unwrought, wrought, and cast products. An additional method for analyzing Copper-tin-lead alloys is provided in Annex B. However, the precision criteria for this method may not be suitable for zinc and phosphorus elements. The applicable elements and their composition ranges are listed in Tables 1 to 6. The ranges can also be extended or adjusted for lower mass fractions. If other elements are included, their interference, sensitivity, resolution, and linearity criteria must be carefully considered for each instrument and wavelength used.
