Fasteners - Non-electrolytically applied zinc flake coating systems (ISO 10683:2018)

This document specifies requirements for non-electrolytically applied zinc flake coating systems for steel fasteners. It is applicable to coatings:
—          with or without hexavalent chromium;
—          with or without top coat;
—          with or without lubricant (integral lubricant and/or subsequently added lubricant).
It is applicable to bolts, screws, studs and nuts with ISO metric thread, to fasteners with non-ISO metric thread, and to non-threaded fasteners such as washers, pins, clips, etc.
This document does not specify requirements for such fastener properties as weldability or paintability. It is not applicable to mechanically applied zinc coatings.
NOTE       Coatings in accordance with this document are especially used for high strength fasteners (≥ 1 000 MPa) to avoid risk of internal hydrogen embrittlement (IHE — see 4.4).
Information for design and assembly of coated fasteners is given in Annex A.

Fixations - Systèmes de revêtements non électrolytiques de zinc lamellaire (ISO 10683:2018)

Le présent document spécifie les exigences relatives aux systèmes de revêtements non électrolytiques de zinc lamellaire pour les fixations en acier. Il s'applique aux revêtements:
—          avec ou sans chrome hexavalent;
—          avec ou sans finition «top coat»;
—          avec ou sans lubrifiant (lubrifiant intégré et/ou lubrifiant additionnel).
Il s'applique aux vis, goujons, tiges filetées et écrous à filetage métrique ISO, aux fixations à filetage non métrique ISO et aux fixations non filetées telles que les rondelles, les goupilles, les clips, etc.
Le présent document ne spécifie aucune exigence pour les caractéristiques des fixations telles que la soudabilité ou l'aptitude à la peinture. Il ne s'applique pas aux revêtements de zinc appliqués mécaniquement (matoplastie).
NOTE       Les revêtements conformes au présent document sont particulièrement utilisés pour les fixations à haute résistance mécanique (≥ 1 000 MPa) afin d'éviter le risque de fragilisation par l'hydrogène interne (IHE, Internal Hydrogne Embrittlement — voir 4.4).
Des informations pour la conception et l'assemblage des fixations revêtues sont données en Annexe A.

Vezni elementi - Cinkova lamelna prevleka, ki ni izdelana z elektrolizo (ISO 10683:2018)

Ta dokument določa zahteve za sisteme cinkovih lamelnih prevlek, ki niso izdelane z elektrolizo, za jeklene vezne elemente. Uporablja se za prevleke:
– s šestvalentnim kromom ali brez njega;
– z vrhnjim premazom ali brez njega;
– z mazivom (integriranim ali naknadno dodanim) ali brez njega.
Uporablja za vijake in matice z ISO-metričnim navojem, vezne elemente z metričnimi navoji, ki niso del ISO, ter vezne elemente brez navojev, kot so podložke, zatiči, objemke itd.
Ta dokument ne določa zahtev za lastnosti veznih elementov, kot je varivost ali možnost barvanja. Ne uporablja se za mehansko nanesene cinkove prevleke.
OPOMBA: Prevleke v skladu s tem dokumentom se uporabljajo zlasti za zelo trdne vezne elemente (≥ 1000 MPa) pri preprečevanju tveganja za notranjo krhkost ob stiku z vodikom (IHE – glej 4.4).
Informacije o projektiranju in sestavljanju prevlečenih veznih elementov so podane v dodatku A.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
