This document specifies tests which are intended to determine the influence of one or more flowing polluting gas(es) at volume fractions less than or equal to 10−6 on test samples and/or articles of metals and alloys with or without corrosion protection under determined conditions of temperature and relative humidity. This document is applicable to a) metals and their alloys, b) metallic coatings (anodic and cathodic), c) metals with conversion coatings, d) metals with anodic oxide coatings, and e) metals with organic coatings.
Abstract
Overview
EN ISO 10062:2022 - Corrosion tests in artificial atmosphere at very low concentrations of polluting gas(es) specifies laboratory test methods to assess the influence of one or more flowing polluting gases at very low volume fractions (≤ 10−6) on metals, alloys and their coatings under defined temperature and relative humidity. The document (adopted by CEN as EN ISO 10062:2022) replaces the 2008 edition and provides requirements for apparatus, test procedure, monitoring and reporting to improve reproducibility of low-concentration gas corrosion tests.
Key topics and technical requirements
- Scope & applicability: Applies to metals and alloys, metallic coatings (anodic/cathodic), conversion coatings, anodic oxide coatings and organic coatings.
- Polluting gases: Typical gases include SO2, NOx, H2S and chlorine compounds; tests may use single gases or mixtures to simulate realistic atmospheres.
- Concentration: Tests target gas volume fractions ≤ 10−6 (very low concentrations).
- Environmental control: Apparatus must maintain uniform conditions and avoid condensation - specified stability is **
