TS EN 12508

TS EN 12508 is a vocabulary standard for corrosion protection of metals and alloys, focused on the language used for surface treatment, metallic coatings and other inorganic coatings. Rather than prescribing a process or test method, it brings together the terms needed to discuss these topics with consistent meaning across technical documents and communication.

How the terminology around surface treatment and coatings is organised

In corrosion protection, surface preparation, coating formation and coating type are related but distinct ideas. Metallic coatings typically rely on a protective metal layer at the surface, while other inorganic coatings may provide different chemical or physical performance characteristics. Clear terminology helps prevent confusion between these processes and supports consistent use in specifications, quality documentation and engineering communication.

The scope states that the list is not complete. It includes only those generic terms considered necessary to clarify processes in this field, so the document should be understood as a selected vocabulary rather than an exhaustive glossary. That makes it especially useful where the same word can be used differently across industries or coating technologies.

• Terminology for corrosion protection of metals and alloys
• General technical terms used in surface treatment processes
• Naming related to metallic and other inorganic coatings
• Selected concepts included to remove ambiguity in practice

As a terminology standard, TS EN 12508 provides conceptual clarity rather than a production recipe or mandatory test procedure. Its value is in establishing a shared technical language for engineers, quality personnel, procurement teams and anyone preparing or reading technical correspondence. This TS EN edition is based on EN 12508:2000 and is listed as withdrawn.
