What is DIN 50961?

What is DIN 50961?

DIN 50961, 2012 Edition, April 2012 – Electroplated coatings – Zinc coatings on iron or steel – Terms, testing and corrosion resistance. This standard is only to be used in conjunction with DIN EN ISO 2081, which specifies requirements to be met by electroplated coatings of zinc with supplementary treatments.

What color is Zincplate?

Zinc plating is available in yellow/gold, clear/blue, black and green, with the addition of topcoats known as “Chromates.” These topcoats can add many more hours of salt spray corrosion protection on the zinc-plated product.

Does zinc plating add thickness?

The protection from the zinc plating is proportional to the thickness of the zinc plating – so thicker zinc means more protection for the base metal. Thickness has almost no effect on the resistance to “white rust” because this involves the coating itself corroding.

What is the thickness of galvanized coating?

3-8 mils
Typical galvanized coatings range from 3-8 mils (75-200 mi- crons) thick. When designing and detailing tapped holes, the increased thickness is important. Best practice suggests that the hole be tapped after galvanizing, removing the coating on the interior mating surface.

How is galvanized thickness measured?

1. Measure the bare substrate at a number of spots to obtain a representative average value. This average value is the base metal reading (BMR).
2. Measure the zinc coating at the number of spots specified in ASTM A123-02.
3. Subtract the base metal reading from the gauge reading to obtain the thickness of the zinc.

Is brass waterproof?

Overall, brass loses its zinc component relatively quickly when submerged in water, causing the metal to weaken and putting its structural integrity at risk. Outside of situations where it’s submerged in water, brass is a great metal for outdoor applications due to its amazing endurance.

What is clear zinc coating?

Clear zinc plating is a colorless chromate conversion coating that is often applied over zinc during the post-plating process. This process results in a protective layer with added corrosion resistance, and it gives the part surface a silver appearance with slight iridescence.

What is DIN EN ISO 2081 for zinc electroplating?

This document is only to be used in conjunction with DIN EN ISO 2081, which specifies requirements to be met by electroplated coatings of zinc with supplementary treatments.

What are the requirements for corrosion resistance for zinc coatings?

Requirements regarding corrosion resistance for zinc coatings which have not been subsequently treated are specified for coatings that are tested using the DIN 50018 – KFW 2,0 S test or the neutral salt spray test (NSS) as in DIN EN ISO 9227. Cr (VI) free passivated and sealed zinc and zinc alloy coatings are defined in DIN 50979.

What does 50969-1 stand for?
