DIN 50965 was a German industrial standard titled "Electroplated coatings on iron and steel – Zinc-iron alloys (ZF) and Zinc-nickel alloys (ZN)." Before the harmonization of European standards (EN), this document was the gold standard for specifying alloy-based zinc plating.

DIN 50965 is a foundational tool for quality assurance and compliance in any industry that uses electroplated tin coatings. Its clear, detailed specifications ensure product reliability, which is crucial for sectors like automotive, electronics, and mechanical engineering.

This is the most current and relevant German standard for this specific application.

As global trade expanded, the need for international harmonization led to the withdrawal of DIN 50965. It was succeeded by DIN EN ISO 2093

: The primary source for German standards. The English translation is approximately €65.40 , and the German original is €52.20 .

: Recommendations for intermediate layers, such as nickel, to prevent "whisker" formation (microscopic tin filaments that can cause electrical shorts). Technical Specifications & Environmental Classes

: Many manufacturing firms maintain PDF archives of withdrawn standards to maintain compliance with older product designs.

This standard specifically succeeded DIN 50965 for electroplated coatings of zinc and zinc alloys (specifically zinc-iron and zinc-nickel) with Cr(VI)-free passivations.

Specifies tin coatings on ferrous and copper-based materials .
