Full title and description

ISO 10289:1999 — Methods for corrosion testing of metallic and other inorganic coatings on metallic substrates — Rating of test specimens and manufactured articles subjected to corrosion tests. This International Standard specifies objective procedures for assessing the performance of decorative and protective metallic and other inorganic coatings on metal substrates after exposure to corrosion tests (natural or accelerated), giving separate ratings for protection of the substrate and for appearance changes of the coating.

Abstract

This standard defines rating methods to evaluate test specimens and manufactured articles that have been exposed to corrosive environments (natural atmospheric exposures or accelerated corrosion tests). It provides criteria and scales for two complementary assessments: (a) the protection level (Rp), which rates how well the coating prevents substrate corrosion, and (b) the appearance level (RA), which rates changes in the coating’s appearance. The method allows for objective reporting while noting that appearance assessment can include subjective elements that should be documented in the test report.

Scope

ISO 10289:1999 applies to the rating and reporting of test specimens and manufactured articles that have been subjected to corrosion tests (natural or accelerated) in order to evaluate metallic and other inorganic coatings on metallic substrates. The standard is intended for both protection assessment (degree to which the coating prevents substrate corrosion) and appearance assessment (degree of visual change to the coating). It covers test-piece preparation, the use of agreed protection of cut edges where relevant, rating scales and reporting requirements to ensure reproducible and comparable results between laboratories and reports.

Key topics and requirements

• Defined rating scales for protection level (Rp) — assessing substrate corrosion beneath/through the coating.
• Defined rating scales for appearance level (RA) — assessing changes in coating appearance (discoloration, blistering, flaking, etc.).
• Guidance on specimen selection and condition (test panels, manufactured articles, exposed surfaces and edges).
• Instructions for documenting test conditions (exposure type, duration, accelerated-test parameters) and any edge protection applied.
• Reporting format recommendations to make results comparable and reproducible across laboratories and test programs.

Summary based on national and technical descriptions of the standard.

Typical use and users

ISO 10289:1999 is used by coating manufacturers, test laboratories, quality engineers, materials and corrosion specialists, product certifiers, and R&D groups involved in developing or qualifying metallic and inorganic coating systems. Typical applications include comparative evaluation of coating systems, quality control of production coatings, failure analysis after environmental exposure, and preparation of test reports for procurement or certification purposes.

Related standards

ISO 10289:1999 replaced earlier methods such as ISO 1462 and draws context from other coating and corrosion standards. It is commonly referenced alongside test-method standards for specific accelerated corrosion tests (e.g., salt spray, cyclic corrosion) and standards that specify coating performance or application methods. National and regional implementations (EN/ISO adaptations) exist for related coating test and specification work.

FAQ

Q: What is this standard?

A: ISO 10289:1999 is an International Standard that specifies rating procedures for evaluating metallic and other inorganic coatings on metallic substrates after corrosion exposure, providing separate ratings for substrate protection and coating appearance.

Q: What does it cover?

A: It covers rating scales and procedures for test specimens and manufactured articles exposed to natural or accelerated corrosion tests, guidance on specimen condition and edge protection, and reporting recommendations to ensure objective and comparable results.

Q: Who typically uses it?

A: Coating manufacturers, independent test laboratories, corrosion/materials engineers, product certifiers, and R&D groups use the standard for comparative testing, quality control, and failure analysis.

Q: Is it current or superseded?

A: The 1999 first edition of ISO 10289 was published in 1999 and has been subject to ISO systematic reviews; the edition has been confirmed (reviewed and confirmed) in subsequent ISO review cycles, most recently confirmed in 2021, so the 1999 edition remains the current published version.

Q: Is it part of a series?

A: ISO 10289 is a stand‑alone test/rating standard focused on coating assessment; it is used alongside other ISO and national standards that specify particular corrosion test methods or coating application/performance requirements (for example various salt-spray and cyclic corrosion test method standards and coating specification standards).

Q: What are the key keywords?

A: corrodion testing, coating rating, appearance rating, protection rating, metallic coatings, inorganic coatings, test specimens, manufactured articles, accelerated testing.
