Overview

EN ISO 3815-1:2005 - Zinc and zinc alloys: Analysis of solid samples by optical emission spectrometry (OES) is a harmonized CEN/ISO method that specifies how to determine the chemical composition of zinc and zinc alloys using optical emission spectrometry. The standard covers sample preparation recommendations, test procedures, calibration strategy, result expression and reporting, and includes informative annexes with commonly used analytical lines, reproducibility data and limits of detection.

Key topics and requirements

Scope and applicability

Applies to analysis of zinc and zinc alloys in accordance with ISO 301 and ISO 752 using OES on solid test pieces.

Sampling and preparation

Sampling shall follow ISO 20081 (method of sampling).
Test pieces must be prepared to suit the spectrometer/sample holder and the apparatus’ operation manual.

Test procedure

Analysis performed on solid samples by optical emission spectrometry (OES).
Each test piece is normally tested at least twice; additional tests if heterogeneity or instrument issues are suspected. Producer labs may average multiple test pieces under defined conditions.

Calibration and reference materials

Preferred calibration order: Certified Reference Materials (CRM), then Reference Materials (RM), then Internal Reference Materials (IRM).
IRMs must have composition determined per ISO 752:2004.
Recalibration at reasonable intervals using reference samples with similar physical/chemical properties.

Expression and reporting of results

Results expressed as mass fraction and calculated as the arithmetic mean of valid single results.
Test report must identify the sample, present test sequence results, laboratory name, date, reference to EN ISO 3815-1:2005 and responsible signature.

Informative performance data

Annex A lists common analytical lines (wavelengths) for elements such as Zn, Pb, Cd, Fe, Cu, Sn, Al and Mg.
Annex B gives example coefficients of variation (reproducibility) for elements at representative concentrations.
Annex C provides example limits of detection (LOD) for spark OES lines (e.g., Cd 228.8 nm LOD ~0.1 µg/g).

Applications and users

Quality control and incoming inspection in zinc production and zinc-alloy manufacturing

Metallurgical laboratories performing composition analysis and certification

Foundries, diecasters and galvanizers monitoring alloying and impurity levels

Standards organizations and conformity assessment bodies implementing harmonized testing procedures
