Fasteners - Electroplated coating systems (ISO 4042:2018)

This document specifies requirements for electroplated coatings and coating systems on steel fasteners. The requirements related to dimensional properties also apply to fasteners made of copper or copper alloys.
It also specifies requirements and gives recommendations to minimize the risk of hydrogen embrittlement; see 4.4 and Annex B.
It mainly applies to zinc and zinc alloy coating systems (zinc, zinc-nickel, zinc-iron) and cadmium, primarily intended for corrosion protection and other functional properties:
—          with or without conversion coating;
—          with or without sealant;
—          with or without top coat;
—          with or without lubricant (integral lubricant and/or subsequently added lubricant).
Specifications for other electroplated coatings and coating systems (tin, tin-zinc, copper-tin, copper-silver, copper, silver, copper-zinc, nickel, nickel-chromium, copper-nickel, copper-nickel-chromium) are included in this document only for dimensional requirements related to fasteners with ISO metric threads.
This document applies 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 and rivets.
Information for design and assembly of coated fasteners is given in Annex A.
This document does not specify requirements for properties such as weldability or paintability.
NOTE       Other International Standards specify differing electroplating processes. For electroplating of fasteners, the requirements of this document apply, unless otherwise agreed.

Verbindungselemente - Galvanisch aufgebrachte Überzugsysteme (ISO 4042:2018)

Dieses Dokument legt Anforderungen an galvanisch aufgebrachte Überzüge und Überzugsysteme auf Ver-bindungselementen aus Stahl fest. Die Maßanforderungen gelten auch für Verbindungselemente aus Kupfer oder Kupferlegierungen.
Es legt außerdem Anforderungen fest und gibt Empfehlungen, um das Risiko der Wasserstoffversprödung zu minimieren; siehe 4.4 und Anhang B.
Es gilt hauptsächlich für Zink- und Zinklegierungsüberzugsysteme (Zink, Zink-Nickel, Zink-Eisen) und Cadmium, die vor allem für den Korrosionsschutz und weitere funktionelle Eigenschaften bestimmt sind:
- mit oder ohne Konversionsschicht;
- mit oder ohne Versiegelung;
- mit oder ohne Deckschicht;
- mit oder ohne Schmiermittel (integriertes Schmiermittel und/oder nachträglich aufgebrachtes Schmier-mittel).
Die Festlegungen für weitere galvanisch aufgebrachte Überzüge und Überzugsysteme (Zinn, Zinn-Zink, Kupfer-Zinn, Kupfer-Silber, Kupfer, Silber, Kupfer-Zink, Nickel, Nickel-Chrom, Kupfer-Nickel, Kupfer-Nickel-Chrom) sind in diesem Dokument nur für Maßanforderungen in Bezug auf Verbindungselemente mit metri-schem ISO-Gewinde enthalten.
Dieses Dokument gilt für Schrauben und Muttern mit metrischem ISO-Gewinde, für Verbindungselemente mit nicht metrischem ISO-Gewinde und für Verbindungselemente ohne Gewinde, wie Scheiben, Stifte, Clips und Niete.
Hinweise zur konstruktiven Ausführung und zur Montage von beschichteten Verbindungselementen sind in Anhang A aufgeführt.
Dieses Dokument legt keine Anforderungen an Eigenschaften wie Schweißbarkeit oder Lackierbarkeit fest.
ANMERKUNG Andere Internationale Normen legen abweichende Galvanikprozesse fest. Für das Aufbringen galvanischer Überzüge auf Verbindungselemente gelten die Anforderungen dieses Dokumentes, sofern nicht anders vereinbart.

Fixations - Systèmes de revêtements électrolytiques (ISO 4042:2018)

Le présent document spécifie les exigences applicables aux revêtements et aux systèmes de revêtement électrolytiques destinés aux fixations en acier. Les exigences portant sur les caractéristiques dimensionnelles s'appliquent également aux fixations en cuivre ou en alliages de cuivre.
Il spécifie également les exigences et donne des recommandations visant à réduire le risque de fragilisation par l'hydrogène; voir 4.4 et Annexe B.
Il s'applique principalement aux systèmes de revêtement de zinc et d'alliage de zinc (zinc, zinc-nickel, zinc-fer) et de cadmium, essentiellement destinés à la protection contre la corrosion et à l'obtention d'autres caractéristiques fonctionnelles:
—          avec ou sans couche de conversion;
—          avec ou sans finitions «sealer»;
—          avec ou sans finition «top coat»;
—          avec ou sans lubrifiant (lubrifiant intégré et/ou lubrifiant additionnel).
Les spécifications concernant d'autres revêtements et systèmes de revêtement électrolytiques (étain, étain-zinc, cuivre-étain, cuivre-argent, cuivre, argent, cuivre-zinc, nickel, nickel-chrome, cuivre-nickel, cuivre-nickel-chrome) sont incluses dans le présent document uniquement pour les exigences dimensionnelles relatives aux fixations à filetage métrique ISO.
Le présent document 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 et les rivets.
Des informations sur la conception et l'assemblage des fixations revêtues sont données à l'Annexe A.
Le présent document ne spécifie pas d'exigence pour les caractéristiques telles que la soudabilité ou l'aptitude à la peinture.
NOTE       Des procédés de revêtement électrolytique différents sont spécifiés dans d'autres Normes internationales. Pour le revêtement électrolytique des fixations, les exigences du présent document s'appliquent, sauf accord contraire.

Mehanski vezni elementi - Sistemi galvanskih prevlek veznih elementov (ISO 4042:2018)

Ta dokument določa zahteve za galvanske prevleke veznih elementov in sisteme prevlek na mehanskih veznih elementih. Zahteve, povezane z dimenzijskimi lastnostmi, veljajo tudi za vezne elemente, izdelane iz bakra in bakrovih zlitin.
Določa tudi zahteve in podaja priporočila za zmanjševanje tveganja za krhkost v stiku z vodikom (glej 4.4. in dodatek B).
Uporablja se predvsem za sisteme cinkovih prevlek ter prevlek iz cinkovih zlitin (cink, cink-nikelj, cink-železo) in kadmija, namenjene predvsem za zaščito proti koroziji in zagotavljanje drugih funkcionalnih lastnosti:
– s konverzijskim premazom ali brez njega;
– s tesnilom ali brez njega;
– z vrhnjim premazom ali brez njega;
– z mazivom (integriranim ali naknadno dodanim) ali brez njega.
Specifikacije za druge galvanske prevleke in sisteme prevlek (kositer, kositer-cink, baker-kositer, baker-srebro, baker, srebro, baker-cink, nikelj, nikelj-krom, baker-nikelj, baker-nikelj-krom) so zajete v tem dokumentu samo za dimenzijske zahteve, povezane z veznimi elementi z ISO-metričnimi navoji.
Ta dokument se 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 in zakovice.
Informacije o projektiranju in sestavljanju prevlečenih veznih elementov so podane v dodatku A. Ta dokument ne določa zahtev za lastnosti veznih elementov, kot je varivost ali možnost barvanja.
OPOMBA: Različne postopke galvanizacije določajo drugi mednarodni standardi. Če ni dogovorjeno drugače, za galvanizirane vezne elemente veljajo zahteve tega dokumenta.
