Understanding DIN 50965: The Standard for Electroplated Coatings and the Role of Digital Access

Significant Surfaces

: Defines the "significant surface" as the area that can come into contact with a 20 mm diameter ball , unless otherwise specified .

DIN EN ISO 19598:

Often mentioned alongside DIN 50965, but it specifically covers zinc and zinc-alloy coatings (like Zn-Ni) with chrome(VI)-free passivation, rather than pure tin . din 50965 pdf

Testing Procedures

: Guidelines for verifying the quality of the tinning through chemical or physical testing. Current Status Pre-treatment : Cleaning and surface preparation to ensure

Key Requirements:

Defines minimum layer thicknesses and specifies the "significant surfaces" (usually defined as areas reachable by a 20 mm ball) . If you are looking for current technical specifications

Pre-treatment: Cleaning and surface preparation to ensure the metal surface is free from oils, greases, and oxides.
Phosphating: Immersion of the prepared metal into a phosphating solution. The solution's composition and process conditions (like temperature and immersion time) are crucial for the coating's quality.
Post-treatment: Rinsing and drying. Depending on the application, additional coatings might be applied.

If you are looking for current technical specifications for tin plating, you should refer to DIN EN ISO 2093
