Overview
EN 15703-2:2014 specifies a validated flame atomic absorption spectrometric (FAAS) method for the determination of manganese content in copper and copper alloys (unwrought, wrought and cast). The method covers manganese mass fractions from 0,0010 % to 6,0 % and defines sampling, sample preparation, reagents, apparatus and calibration procedures required for reliable quantitative analysis.
Key topics and requirements
- Scope and applicability: Applicable to copper and copper alloys in unwrought, wrought and cast forms with Mn between 0.0010% and 6.0%.
- Sampling: Follow ISO 1811-1 / ISO 1811-2 for selection and preparation. Test samples are fine drillings, chips or millings (maximum thickness 0.5 mm).
- Principle: Dissolution in hydrochloric and nitric acids, masking of interferences with lanthanum(III) chloride, aspiration into an air/acetylene flame and measurement of Mn atomic absorption (279.5 nm or 403.1 nm lines) using a manganese hollow-cathode lamp.
- Reagents and matrix control:
- Hydrochloric acid (HCl), nitric acid (HNO3), hydrofluoric acid (HF - with safety warnings), lanthanum chloride, sulphuric acid.
- Preparation of manganese stock/standard solutions and copper matrix solutions (2 g/l and 20 g/l Cu) to match matrix effects.
- Sample preparation:
- Detailed digestion steps including treatment for silicon-bearing samples (ashing, HF treatment) to avoid bias.
- Dilution schemes vary by expected Mn range (several prescribed dilution paths for 0.001–0.02%, 0.02–0.50%, 0.50–2.0%, 2.0–6.0%).
- Calibration and quality control:
- Matrix-matched calibration curve (seven-point series), bracketing options and use of copper matrix to compensate chemical interaction effects.
- Blank tests, check tests with reference materials or synthetic samples, and instrument checks required.
- Apparatus: Atomic absorption spectrometer with air/acetylene burner and Mn hollow-cathode lamp.
- Safety: Explicit warning about hydrofluoric acid hazards and general chemical-handling precautions.
Applications and users
EN 15703-2:2014 is used for:
- Quality control and incoming inspection in copper alloy manufacturing (electrical, plumbing, brazing alloys, bearing materials).
- Metallurgical laboratories performing composition certification and conformity testing.
- Materials testing for product certification, traceability and regulatory compliance.
- Failure analysis and R&D, when precise manganese determination affects alloy properties (strength, corrosion resistance, conductivity).
Typical users: QC managers, analytical chemists, metallurgists, accredited testing labs and standards bodies.
