Method for the simulation of accelerated wear and corrosion for the detection of nickel release from coated items

This document specifies a method for the simulation of accelerated wear and corrosion, to be used prior
to the detection of nickel release from coated articles that come into direct and prolonged contact with
the skin. According to the Commission Regulation (EC) No 1907/2006 (REACH), articles with an outer
coating containing nickel and those which are inserted into pierced ears and other parts of the human
body are excluded from the scope of this document.

Simulierte Abrieb- und Korrosionsprüfung zum beschleunigten Nachweis der Nickelabgabe von mit Auflagen versehenene Gegenständen

Dieses Dokument legt ein Verfahren zur Simulation von beschleunigtem Abrieb und Korrosion fest, das vor dem Nachweis der Nickelabgabe von mit Auflagen versehenen Erzeugnissen anzuwenden ist, welche mit der Haut in direkte und länger andauernde Berührung kommen. Entsprechend der Verordnung der Kommission (EG) Nr. 1907/2006 (REACH) sind Erzeugnisse mit einer nickelhaltigen Außenbeschichtung und solche, die in durchstochene Ohren oder andere Körperteile des menschlichen Körpers eingeführt werden, vom Anwendungsbereich dieses Dokument ausgenommen.

Methode pour la simulation de accélérée de l´usure et de la corrosion pour la détermination du nickel libéré par les objects revêtus

Introduction

The wear and corrosion of objects in contact with the skin depends very much on the composition,

environment, and shape of the article and the activities of the person concerned. 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 articles in contact

with the skin, which may be subject to several kinds and varying degrees of wear.

In order to show compliance with the Commission Regulation (EC) No 1907/2006 (REACH) of the

European Parliament and the Council in the current version, articles should be tested in accordance

with the appropriate European harmonized 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 1811, EN 16128 and this document.

1 Scope

This document specifies a method for the simulation of accelerated wear and corrosion, to be used prior

to the detection of nickel release from coated articles that come into direct and prolonged contact with

the skin. According to the Commission Regulation (EC) No 1907/2006 (REACH), articles with an outer

coating containing nickel and those which are inserted into pierced ears and other parts of the human

body are excluded from the scope of this document.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

EN 1811, Reference test method for release of nickel from all post assemblies which are inserted into

pierced parts of the human body and articles intended to come into direct and prolonged contact with the

skin

EN 16128, Ophthalmic optics — Reference method for the testing of spectacle frames and sunglasses for

nickel release
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
article

object that is subjected to the nickel release requirements according to Entry 27 of Annex XVII of

Commission Regulation (EC) No 1907/2006 (REACH)
3.2
test part

article or sub-part of a dismantled and/or cut article that has to be tested according to EN 1811 or

EN 16128
4 Principle

The articles to be tested are exposed to a corrosive atmosphere before being placed into a tumbling

barrel together with a wear medium of abrasive paste and granules. The barrel is rotated so as to

subject the test parts to wear from the wear medium. The test parts are then tested for nickel release in

accordance with the applicable European standard.

NOTE EN 1811 is applicable to all products except spectacle frames and sunglasses. EN 16128 is applicable to

spectacle frames and sunglasses.

If only indicative information on the extent of nickel release or the presence of nickel is required, such

information can be obtained by performing the tests specified in CR 12471.
