Full title and description

ISO 10308:2006 — Metallic coatings — Review of porosity tests. This International Standard reviews published methods for revealing pores and other discontinuities in a wide range of metallic, inorganic and organic coatings on various base metals; it summarises test principles that produce an observable reaction with the substrate when a discontinuity is present.

Abstract

ISO 10308:2006 surveys and summarises porosity and continuity test methods (see also ISO 2080) for coatings such as aluminium and anodized aluminium, brass, cadmium, chromium, cobalt, copper, gold, indium, lead, nickel and its alloys, palladium, platinum, vitreous or porcelain enamel, rhodium, silver, tin and tin alloys, zinc and chromate/phosphate conversion coatings (including associated organic films) on substrates including aluminium, beryllium‑copper, brass, copper, iron, NiFeCo alloys, magnesium, nickel and zinc alloys. The tests described are designed to react with exposed substrate at discontinuities to form an observable reaction product.

Scope

ISO 10308:2006 provides a review (not a prescriptive single test method) of published porosity and continuity tests applicable to many metallic and inorganic/organic coatings on a broad range of substrates. It aims to inform users about available test principles, the kinds of defects they reveal, and the coating/substrate combinations for which particular tests have been used; it also cross‑references relevant specific test standards (for example ISO 2080 and other discipline standards).

Key topics and requirements

• Catalogue of published porosity and continuity test principles (chemical, electrochemical and environmental exposure techniques) and the observable reaction products they produce.
• Coating and substrate combinations covered (extensive list of metals, alloys and conversion coatings).
• Guidance on which tests are appropriate for particular coating types and defect sizes.
• Notes on pore morphology and how pore orientation/shape affects detectability.
• Cross‑references to specific test standards (e.g., ISO 2080 and other normative references) and relevant national/industry practices.

Typical use and users

Primary users are coating manufacturers, electroplaters, surface‑treatment specialists, quality and failure‑investigation laboratories, corrosion engineers, product specifiers and standards committees. The document is used as a reference guide to select appropriate porosity/continuity tests, to interpret test results in context of coating/substrate combinations, and to support development of test schedules in procurement and quality control.

Related standards

ISO 10308 is a review/reference document and cross‑references multiple specific test standards and industry practices. Notable related standards and test methods include ISO 2080 (electroplating vocabulary and related methods referenced in porosity testing) and specific continuity tests such as copper sulphate contact tests for anodized aluminium (see ISO 2085 and related revisions). National and industry test practices (ASTM, DIN/EN adoptions) for porosity testing of particular coatings (gold, silver, solderable platings, etc.) are also commonly consulted alongside ISO 10308.

FAQ

Q: What is this standard?

A: ISO 10308:2006 is an International Standard that reviews published methods for revealing pores and discontinuities in a wide range of metallic and related coatings; it summarises test principles rather than prescribing a single mandatory procedure.

Q: What does it cover?

A: It covers the principles and typical applications of porosity and continuity tests for many coatings (electroplate, platings, enamel, conversion coatings and associated organic films) on numerous base metals and alloys, and it points to specific test standards where appropriate.

Q: Who typically uses it?

A: Coating and surface‑treatment manufacturers, independent test laboratories, corrosion and failure analysts, procurement/specification writers, and standards developers use ISO 10308 as a reference when selecting or evaluating porosity/continuity tests.

Q: Is it current or superseded?

A: ISO 10308:2006 (Edition 2) is the published edition from January 2006; the ISO record shows it was subject to periodic systematic review and was last confirmed as the current version in 2021, so the 2006 edition remains the active/confirmed text. The 1995 edition was withdrawn and replaced by the 2006 edition.

Q: Is it part of a series?

A: ISO 10308 is a review/reference document within the family of standards addressing metallic coatings, electroplating vocabulary and specific test methods; it cross‑references other ISO standards (for example ISO 2080 and tests such as the copper sulfate test covered by ISO 2085) and is often consulted together with dedicated test standards and national/adopted versions.

Q: What are the key keywords?

A: Porosity, pore detection, continuity test, metallic coatings, electroplating, anodizing, inspection, coating defects, substrate reaction.
