TS EN ISO 1891-2/A1

TS EN ISO 1891-2/A1 is an amendment to the ISO 1891-2 vocabulary for coatings used with fasteners. In practical terms, this kind of document helps keep technical language consistent across design, procurement, manufacturing, and inspection by aligning the meaning of coating-related terms such as coating, surface treatment, and protective layer.

Why coating terminology matters

In the general fastener context, coatings are commonly associated with corrosion resistance, friction behavior, appearance, and assembly performance. A coating may be metallic or non-metallic, and it is applied to the base component to modify surface properties or help the part perform better in service. Vocabulary standards do not define a product’s performance by themselves; they define how the concepts should be named and understood.

What this amendment means as a document type

This listing is an amendment, not a standalone rewritten standard. Its subject remains the terminology framework for coatings on fasteners, with the amendment serving to adjust the underlying vocabulary document. Without the full text, the exact clauses or definitions changed by Amendment 1 should not be inferred from the catalogue record alone.

• An amendment to a vocabulary standard for fastener coatings.
• Focuses on terminology and definitions rather than test methods.
• Supports consistent use of coating-related language across technical documents.
• Covers the conceptual area of surface systems used for protection, function, or appearance.
