Method for the simulation of wear and corrosion for the detection of nickel release from coated items
This European Standard specifies a method for accelerated wear and corrosion, to be used prior to the detection of nickel release from coated items that come into direct and prolonged contact with the skin.

This procedure attempts to simulate the wear and corrosion on a coated article during two years of normal use.
By its nature this is a pragmatic solution to the problems posed by the evaluation of coated items in contact with the skin, which may be subject to several kinds and varying degrees of wear. In order to show compliance with Directive 94/27/EC, items should be tested in accordance with the appropriate European harmonised standard(s), the references of which have been published by the European Commission in the Official Journal of the European Communities.
Currently, these are EN 1810, EN 1811 and this European Standard. SIST EN 12472:2006+A1:2009
The barrel is rotated so as to subject the test pieces to wear from the wear medium.
The items are then tested for nickel release in accordance with EN 1811. 4 Reagents and materials Except where indicated, all reagents and materials that can come into contact with samples or reagents shall be demonstrably free of nickel, and all reagents shall be of recognized analytical grade or better. 4.1 Corrosion 4.1.1 Container Container with a lid and a device for suspending the test pieces, all parts made of inert material (e.g. glass or plastic).
