Metallic and other inorganic coatings - Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc-aluminium alloys - Test methods (ISO 3613:2021)
This document specifies methods for the determination of
— the presence of colourless chromate conversion coatings,
— the presence of hexavalent chromium in colourless and coloured coatings on zinc or cadmium or aluminium-zinc (mass fraction of aluminium: 55 %, within a range of 54 % to 56 % mass fraction) and zinc-aluminium (mass fraction of aluminium: 5 %) alloys,
— the total chromium content per unit area on zinc and cadmium,
— the mass per unit area of both colourless and coloured coatings,
— the satisfactory adhesion of chromate conversion coatings, and
— the quality of chromate coatings.
These methods are applicable to
— colourless and coloured chromate conversion coatings containing trivalent and hexavalent chromium in varying proportions and produced by either chemical or electrochemical processes, and
— chromate coatings that are free from any supplementary coatings, such as oil, water or solvent-based polymers or wax.
Metallische und andere anorganische Überzüge - Chromatierüberzüge auf Zink, Cadmium, Aluminium-Zink- und Zink-Aluminium-Legierungen - Prüfverfahren (ISO 3613:2021)
Dieses Dokument legt Verfahren fest zur Bestimmung
- des Vorhandenseins farbloser Chromatierüberzüge,
- des Vorhandenseins von sechswertigem Chrom in farblosen und farbigen Überzügen auf Zink oder Cadmium oder Legierungen aus Aluminium-Zink (mit einem Massenanteil von 55 % Aluminium in einem Bereich von 54 % bis 56 % Massenanteil) und aus Zink-Aluminium (mit einem Massenanteil von 5 % Aluminium),
- des Gesamtchromgehalts je Flächeneinheit auf Zink und Cadmium,
- der flächenbezogenen Masse farbloser und farbiger Überzüge,
- der zufriedenstellenden Haftfestigkeit von Chromatierüberzügen und
- der Qualität von Chromatierüberzügen.
Diese Verfahren sind anwendbar
- auf farblose und farbige Chromatierüberzüge, die dreiwertiges und sechswertiges Chrom in veränderlichen Anteilen enthalten und durch chemische oder elektrochemische Verfahren erzeugt wurden, und
- auf Chromatierüberzüge, die frei von zusätzlichen Schichten sind, wie Öl, in Wasser oder Lösemittel gelösten Polymeren oder Wachs.

Revêtements métalliques et autres revêtements inorganiques - Couches de conversion au chromate sur zinc, cadmium et alliages d'aluminium-zinc et de zinc-aluminium - Méthodes d'essai (ISO 3613:2021)
Le présent document spécifie des méthodes permettant de déterminer:
— la présence de couches de conversion au chromate incolores;
— la présence de chrome hexavalent dans les couches incolores ou colorées sur zinc, cadmium ou alliages d’aluminium-zinc (fraction massique d’aluminium de 55 %, dans une plage de 54 % à 56 %) et de zinc-aluminium (fraction massique d’aluminium de 5 %);
— la teneur totale en chrome par unité de surface sur zinc et cadmium;
— la masse par unité de surface des couches incolores et colorées;
— le degré d’adhérence des couches de conversion au chromate;
— la qualité des couches de chromate.
Ces méthodes s’appliquent:
— aux couches de conversion au chromate incolores et colorées contenant du chrome trivalent et hexavalent en diverses proportions et produites par un procédé chimique ou électrochimique;
— aux couches de chromate exemptes de tout revêtement supplémentaire tel que huile, polymère à base d’eau ou de solvant, ou cire.

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
