About This Item
TS EN ISO 1891-2 is a terminology standard for coatings used on fasteners. In this part, coating-related language is organised around corrosion protection and functional purposes, giving a common technical vocabulary for the surface layers applied to fasteners and the concepts used to describe them.
Why coatings need their own vocabulary
On fasteners, a coating is more than a visual finish. It can influence corrosion resistance, friction during tightening, assembly behavior and, in some cases, electrical or decorative characteristics. Clear definitions matter because the same coating-related term may be used differently across manufacturing, design and procurement unless it is anchored to a shared terminology standard. Such standards primarily harmonise language rather than impose performance requirements.
What this part covers in technical context
The scope of ISO 1891-2 is to specify terms and definitions for fastener coatings. In general technical terms, that means the vocabulary used to identify coating types, their purpose and related concepts for metallic or other suitable surfaces on fasteners. Corrosion protection is a major reason coatings are applied, helping fasteners better withstand environmental exposure; functional coatings may also support lower wear, controlled friction or easier assembly. The standard should be understood as a terminology reference, not as a source of coating selection rules or performance limits.
