(Main)Metallic and other inorganic coatings - Electroplated coatings of zinc with supplementary treatments on iron or steel (ISO 2081:2018)
Metallic and other inorganic coatings - Electroplated coatings of zinc with supplementary treatments on iron or steel (ISO 2081:2018)
ISO 2081:2018 specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating.
ISO 2081:2018 is not applicable to zinc coatings applied
- to sheet, strip or wire in the non-fabricated form,
- to close-coiled springs, or
- for purposes other than protective or decorative.
ISO 2081:2018 does not specify requirements for the surface condition of the basis metal prior to electroplating with zinc. However, defects in the surface of the basis metal can adversely affect the appearance and performance of the coating.
The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including class or fit.
Metallische und andere anorganische Überzüge - Galvanische Zinküberzüge auf Eisenwerkstoffen mit zusätzlicher Behandlung (ISO 2081:2018)
Dieses Dokument legt Anforderungen an galvanisch abgeschiedene Zinküberzüge auf Eisenwerkstoffen mit zusätzlicher Behandlung fest. Es enthält Informationen, die der Auftraggeber dem galvanischen Betrieb geben muss, sowie Anforderungen an die Wärmebehandlung vor und nach der galvanischen Metallabschei-dung.
Es gilt nicht für Zinküberzüge
- auf Blechen, Bändern oder Draht in unbearbeiteter Form,
- auf engspiraligen Federn oder
- für andere Zwecke als zum Korrosionsschutz oder zur Dekoration.
Dieses Dokument legt keine Anforderungen an die Oberflächenbeschaffenheit des Grundmetalls vor der galvanischen Zinkabscheidung fest. Fehler in der Oberfläche des Grundmetalls können jedoch das Aussehen und die Gebrauchstauglichkeit von Zinküberzügen ungünstig beeinflussen.
Die auf Verbindungselemente mit Gewinde aufzubringende Schichtdicke kann durch Abmessungsanfor-derungen, wie Klasse oder Passung, begrenzt sein.
Revêtements métalliques et autres revêtements inorganiques - Dépôts électrolytiques de zinc avec traitements supplémentaires sur fer ou acier (ISO 2081:2018)
ISO 2081:2018 spécifie les exigences applicables aux dépôts électrolytiques de zinc avec traitements supplémentaires sur le fer ou l'acier. Il inclut les informations à fournir par l'acheteur à l'électroplaste, ainsi que les exigences relatives au traitement thermique avant et après dépôt électrolytique.
ISO 2081:2018 n'est pas applicable aux revêtements de zinc appliqués:
- sur tôles, feuillards ou fils à l'état non façonné;
- sur des ressorts à spirales serrées;
- dans un autre but que la protection ou la décoration.
ISO 2081:2018 ne spécifie pas d'exigence relative à l'état de surface du métal de base avant dépôt électrolytique de zinc. Toutefois, la présence de défauts à la surface du métal de base peut avoir une incidence négative sur l'aspect et la performance du revêtement.
L'épaisseur du revêtement susceptible d'être appliqué sur les pièces filetées peut être limitée par des exigences dimensionnelles, y compris la classe ou l'ajustement.
Kovinske in druge anorganske prevleke - Galvanske prevleke cinka z dodatno obdelavo na železu in jeklu (ISO 2081:2018)
Ta dokument določa zahteve za galvanske cinkove prevleke z dodatno obdelavo na železu in jeklu. Zajema informacije, ki jih mora kupec dostaviti izdelovalcu galvanske prevleke, in zahteve za prevleke za toplotno obdelavo pred in po galvanizaciji.
Ne uporablja se za cinkove prevleke:
– za pločevine, trakove ali žice v nepredelani obliki,
– za vijačne vzmeti ali
– za uporabe, katerih namen ni zaščita ali okrasitev.
Ta dokument ne določa zahtev za stanje površine osnovne kovine pred galvanizacijo s cinkom. Vendar pa defekti na površini osnovne kovine lahko negativno vplivajo na videz in učinkovitost prevleke.
Debelina prevleke, ki se lahko nanese na navojne komponente, je lahko omejena z dimenzijskimi zahtevami, vključno z razredom ali prileganjem.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

This fourth edition cancels and replaces the third edition (ISO 2081:2008), which has been technically
revised. The following main changes have been made:
— the number of normative references has been reduced;
— reference to ASTM B117 has been replaced with ISO 9227;
— some abbreviated terms have been removed;
— coating designations have been modified;
— reference to ISO 1463 for thickness measurement has been increased;
