Hearing protectors - General requirements - Part 2: Earplugs; German version EN 352-2:2020+A1:2024


DIN EN 352-2 specifies requirements on construction, design, performance, marking and user information for earplugs. Amendment 1 adds requirements for under-the-chin banded earplugs. In particular, DIN EN 352-2 specifies requirements regarding the sound attenuation of the earplugs, measured in accordance with DIN EN ISO 4869-1:2019-10. This document applies to earplugs designed for users who are able to follow supplied instructions and understand the related risks, can fit the earplugs correctly and can give feedback on the performance. Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the user, the device and where possible the working environment in which the device is likely to be used.
