CEN has published EN 1811:2023 for the release of nickel. Conflicting national standards are to be withdrawn by August 2023.
In February 2023, the European Committee for Standardization (Comité Européen de Normalisation, CEN) published EN 1811:2023, the latest reference test method for the release of nickel from all post assemblies that are inserted into pierced parts of the human body and articles intended to come into direct and prolonged contact with the skin in order to determine whether such articles are in compliance with entry No. 27 to Annex XVII of Regulation (EC) 1907/2006 (REACH).
It is important to note that spectacle frames and sunglasses are not within the scope of EN 1811:2023 as these are subject to the requirements of EN 16128 ‘Ophthalmic optics - Reference method for the testing of spectacle frames and sunglasses for nickel release’
Highlights of major changes brought in by EN 1811:2023 are summarized in Table 1.
