To address these requirements new symbols have been developed and  included in ISO 15223-1:2021 Medical devices — Symbols to be used with information to be supplied by the manufacturer — Part 1: General requirements. Alongside, MedTech Europe has published a guidance on the use of symbols which provides translation tables for most of them as well as an Annex for symbols to be used on the implant card.

All symbols included in the ISO 15223-1: 2021 are internationally recognised symbols. In the European Union, ISO 15223-1 has been harmonised to the MDR. Therefore, in the EU these symbols do not need to be described in the information supplied with the device (as per MDR Annex I, 23. 1 h).
