European foreword
This document (EN 12472:2020) has been prepared by Technical Committee CEN/TC 347 “Methods for
analysis of allergens”, the secretariat of which is held by SNV.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2021, and conflicting national standards shall
be withdrawn at the latest by March 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12472:2005+A1:2009.
This document includes the revised text of EN 12472:2005+A1:2009, as well as the changes proposed
by CEN/TC 170 regarding spectacle frames and sunglasses.
The major changes are:
— reference to Regulation (EC) No 1907/2006 (REACH) instead of Directive 94/27/EC;
— use of the term article instead of items, in order to adopt the use of terms in the REACH Regulation;
— update of normative references;
— clarification of articles covered by the scope of this document;
— clarification of concentration of the lactic acid stock solution;
— requirements for granules have been changed;
— A.3 regarding spectacle frames has been updated;
— the document has been editorially updated.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
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.
5 Reagents and materials
5.1 General
Except where indicated, all reagents and materials that can come into contact with test parts or
reagents shall be demonstrably free of nickel, and all reagents shall be of recognized analytical grade or
better.
5.2 Corrosion
