EN ISO 4521:2008

Metallic and other inorganic coatings - Electrodeposited silver and silver alloy coatings for engineering purposes - Specification and test methods (ISO 4521:2008)

ISO 4521:2008 specifies requirements for electroplated silver and silver alloy coatings for electrical, electronic and other engineering applications, including test methods. Engineering applications are defined as those in which the coating essentially serves a non-decorative purpose.
Although ISO 4521:2008 does not specify the condition, finish or surface roughness of the basis material prior to electroplating, the appearance and serviceability of electroplated silver and silver alloy coatings depends on the condition of the basis material. It is essential that the purchaser specifies the surface finish and roughness of the basis material in order to conform to the product requirements.
ISO 4521:2008 does not apply to coatings on screw threads or to coatings on sheet, strip or wire in the non-fabricated form.

Metallische Überzüge und andere anorganische Überzüge - Galvanische Silber- und Silberlegierungs-Überzüge für technische Zwecke - Anforderungen und Prüfverfahren (ISO 4521:2008)

Diese Internationale Norm legt Anforderungen an galvanische Silber- und Silberlegierungs-Überzüge für elektrische, elektronische und andere technische Anwendungen fest, einschließlich der Prüfverfahren. Technische Zwecke werden als solche definiert, bei denen die Überzüge im Wesentlichen zu nicht dekorativen Zwecken dienen.
Diese Internationale Norm legt nicht Beschaffenheit, Aussehen und Rauheit des Grundmaterials vor der elektrolytischen Abscheidung fest.
Diese Internationale Norm gilt nicht für Verbindungselemente mit Gewinden oder für Überzüge auf Blechen und Bändern in unbearbeiteter Form.

Revêtements métalliques et autres revêtements inorganiques - Dépôts électrolytiques d'argent et d'alliages d'argent pour applications industrielles - Spécifications et méthodes d'essai (ISO 4521:2008)

L'ISO 4521:2008 spécifie des exigences pour les dépôts électrolytiques d'argent et d'alliages d'argent destinés à des applications électriques, électroniques ou à d'autres applications industrielles et indique des méthodes d'essai. Les applications industrielles sont celles pour lesquelles le dépôt assure essentiellement une fonction non décorative.
Bien que l'ISO 4521:2008 ne spécifie pas l'état initial, la finition ou la rugosité de surface du matériau de base avant le dépôt électrolytique, l'aspect et l'aptitude à l'usage des dépôts électrolytiques d'argent et d'alliages d'argent dépendent de l'état du matériau de base. Il est essentiel que l'acheteur spécifie la finition de surface et la rugosité du matériau de base afin de se conformer aux exigences du produit.
L'ISO 4521:2008 ne s'applique pas aux revêtements des filetages de vis ni à ceux des feuilles, bandes ou fils sous forme non-façonnée.
