Full title and description

ISO 10062:2022 — Corrosion tests in artificial atmosphere at very low concentrations of polluting gas(es). This International Standard specifies test procedures intended to determine the influence of one or more flowing polluting gases at very low volume fractions (≤ 10−6) on test samples and articles of metals and alloys, with or without corrosion protection, under controlled temperature and relative humidity.

Abstract

ISO 10062:2022 defines laboratory corrosion tests using artificial atmospheres containing one or more polluting gases at volume fractions less than or equal to 1 × 10−6. The tests evaluate the effect of such trace gaseous pollutants on metals, metallic coatings, conversion and anodic oxide coatings, and organic coatings under specified temperature and humidity conditions. The standard describes test purpose, general test arrangements, specimen types, environmental conditions, and reporting requirements for assessing corrosion behaviour in low‑concentration gas atmospheres.

Scope

This standard is applicable to laboratory corrosion tests designed to determine the influence of flowing polluting gas(es) at very low concentrations (≤ 10−6 by volume) on metallic test specimens and coated articles. It covers test types and conditions suitable for metals and their alloys, metallic coatings (anodic and cathodic), conversion coatings, anodic oxide coatings and organic coatings, under specified temperature and relative humidity regimes. The standard is intended for controlled evaluation in artificial atmospheres rather than for in‑service or atmospheric field exposure.

Key topics and requirements

• Definition of test intent and selection criteria for gases at volume fractions ≤ 1 × 10−6.
• Specification of specimen types (metals, alloys, metallic and organic coatings) and preparation requirements.
• Test apparatus and chamber requirements for flowing gas atmospheres with controlled temperature and relative humidity.
• Control and measurement of gas concentration, flow rate and exposure duration appropriate to low‑concentration tests.
• Required test conditions (temperature and relative humidity ranges) and typical conditioning/pre‑exposure procedures.
• Criteria and methods for post‑exposure evaluation (visual inspection, mass change, appearance, and other agreed assessment techniques) and reporting format.
• Instructions for recording test parameters, deviations, and interpretation guidance for comparative testing.

Typical use and users

ISO 10062 is used by corrosion testing laboratories, materials and coatings manufacturers, quality and reliability engineers, research organizations, and standards committees. Typical uses include comparative screening of materials and coatings for sensitivity to trace gaseous pollutants, failure investigation where low‑concentration gases are suspected, product development, and conformity assessment where performance in low‑pollutant atmospheres is relevant.

Related standards

Relevant and complementary standards include other ISO/TC 156 documents and corrosion test methods such as ISO 9227 (salt spray tests), ISO 9223 (corrosivity of atmospheres — classification), ISO 8407 (removal of corrosion products from corrosion test specimens) and national/adopted versions (for example EN ISO 10062:2022). Earlier editions of this standard include ISO 10062:2006 and earlier revisions.

FAQ

Q: What is this standard?

A: ISO 10062:2022 is an International Standard that specifies laboratory test methods for assessing the effect of very low concentrations (≤ 1 × 10−6 by volume) of polluting gases on metals and coated articles under controlled temperature and humidity.

Q: What does it cover?

A: It covers test intent, specimen types and preparation, test chamber and apparatus requirements, control of gas concentration and flow, specified temperature and relative humidity conditions, post‑exposure evaluation methods and reporting requirements for low‑concentration gas corrosion tests.

Q: Who typically uses it?

A: Corrosion laboratories, materials and coatings manufacturers, quality and reliability engineers, product developers, academic researchers and standards bodies use this standard for comparative testing, product development and failure analysis related to trace gaseous pollutants.

Q: Is it current or superseded?

A: The current published edition is ISO 10062:2022 (3rd edition, published November 2022). A formal amendment (ISO 10062:2022/Amd 1) was published in June 2024. As of February 15, 2026, ISO 10062:2022 with Amendment 1 (2024) is the latest published version.

Q: Is it part of a series?

A: ISO 10062 is part of the family of ISO standards addressing corrosion testing and evaluation produced under ISO/TC 156 (Corrosion of metals and alloys). It complements other corrosion test standards (for example ISO 9227 and ISO 9223) rather than forming a formal numeric series.

Q: What are the key keywords?
