Leaching of nickel from post assemblies and articles

Allergy to nickel is the most common form of contact allergy. The symptoms usually occur when you are in contact with objects that emit nickel.

Purpose

Products to be tested for nickel emission in accordance with EN 1811 are immersed in a synthetic sweat solution in a sealed container for one week. The temperature is kept at a constant 30° C. Analysis is performed after one week. The results show the amount of nickel leached from the sample.

The EN 12472 test is intended for objects with surface coatings. First, the sample is subjected to wear and corrosion equivalent to two years of daily use. Following that, the sample is treated as per EN 1811.

Products tested using the above methods are watches, clothing buckles, garment buttons, hairpins, metal components for eyeglasses, jewellery, handles, etc.
