Overview

EN 15022-4:2011 is a CEN European Standard that specifies a flame atomic absorption spectrometric (FAAS) procedure for the determination of tin content in copper and copper alloys. The method applies to unwrought, wrought and cast products and is designed for medium tin mass fractions between 0.2 % and 3.0 %. Key instrumentation includes a nitrous oxide/acetylene flame and a tin hollow‑cathode lamp, typically measuring the 286.3 nm spectral line.

Key Topics

• Scope and sample forms: Applicable to drillings, chips or millings (max thickness 0.5 mm) from unwrought, wrought and cast copper alloys.
• Sample preparation: Typical test portion is 1 g dissolved using hydrochloric acid and hydrogen peroxide, then diluted to a defined final volume (test solutions commonly prepared to 100 ml). A blank and a check test (reference or synthetic sample) are carried out concurrently.
• Reagents and standards: Uses analytical‑grade reagents such as concentrated HCl, H2O2 (free from tin stabilizers), a 1 g/l Sn stock solution and a copper base solution (20 g/l Cu) to match matrix effects.
• Instrumentation and wavelengths: FAAS with a nitrous oxide/acetylene burner; tin hollow‑cathode lamp at 286.3 nm (235.5 nm noted as an alternative). Flame should be on oxidising conditions and burner/gas flows adjusted for maximum absorbance.
• Calibration and matrix matching: Calibration solutions (typically a series of eight) are prepared using the tin stock solution and copper base solution so that copper, chloride and acidity reflect the test solutions. The calibration curve must be linear within the working range; bracketing with ±10 % solutions is recommended when appropriate.
• Quality controls: Carry out blank tests, check tests with reference materials, and perform analyses in duplicate.

Applications

This standard is tailored for laboratories performing routine elemental analysis and quality control in metallurgy, alloy production and materials verification. Typical uses:

• Quality control in alloy manufacturing to confirm tin content in lead‑free and traditional copper alloys.
• Metallurgical testing and certification where medium tin levels (0.2–3.0 %) impact physical properties or alloy classification.
• Regulatory compliance and inspection when accurate tin determination is required for product specifications.

Practical advantages include a rapid instrumental procedure, good sensitivity in the medium‑tin range, and straightforward sample workflows suitable for QC laboratories.

Related Standards

• EN 15022-1 (titrimetric method) - planned part for titrimetric determination.
• CEN/TS 15022-2 (spectrophotometric method).
• EN 15022-3 (FAAS method for low tin content).

For reliable results follow EN 15022-4:2011 recommendations on matrix matching, blank and check tests, and duplicate determinations to ensure traceable, reproducible tin measurements in copper alloys.
