ISO 1891-2:2014/Amd 1:2020 PDF

Overview

ISO 1891-2:2014/Amd 1:2020 is an ISO amendment to Part 2 of the ISO 1891 series - the vocabulary and definitions dealing with coatings for fasteners. Prepared by ISO/TC 2 (Fasteners) SC 14 in cooperation with CEN/TC 185, this amendment issues editorial and terminology clarifications to the original 2014 document. It refines key term presentation (for example changing “finish” and “coating” to “finish - coating”) and updates wording in notes (e.g., replacing “usually carried with” with “typically performed with”). The amendment helps ensure consistent use of coating-related terms across international fastener standards and technical documents.

Key Topics

• Terminology for surface coatings used on fasteners (vocabulary and definitions rather than test methods or performance limits).
• Editorial clarifications and corrections to Part 2 entries (as introduced by Amendment 1, 2020).
• Alignment and harmonization between ISO and CEN terminology development (Vienna Agreement collaboration).
• Maintenance and referencing guidance for users of the ISO 1891 series (lists available via ISO).

Note: ISO 1891-2 is a vocabulary standard - it does not set coating performance requirements or procedures; it standardizes language to reduce ambiguity.

Applications

• Creating clear technical specifications and procurement documents that reference coating types and finishes for bolts, screws, nuts and other fasteners.
• Writing test reports, inspection criteria, datasheets and quality manuals where precise coating terminology is required.
• Harmonizing documentation between manufacturers, coating suppliers and OEMs to avoid misinterpretation of terms.
• Supporting standards development and conformity assessment by providing a consistent lexical base for surface-coating related clauses.

Who Should Use This Standard

• Fastener manufacturers and supply chain quality teams
• Coating suppliers and surface-treatment specialists
• Design and procurement engineers specifying coated fasteners
• Testing and inspection laboratories preparing reports or interpreting specifications
• Standards committees and technical writers producing related standards or product literature
