Hearing protectors - General requirements - Part 2: Earplugs
This document specifies construction, design, performance, labeling and user information requirements for earplugs. In particular, it specifies the requirements regarding the sound insulation of the earplugs, measured in accordance with EN ISO 4869-1:2018. This document applies to earplugs designed for users who are able to follow the instructions provided and understand the risks involved, use the earplugs correctly and provide feedback on performance. Ergonomic aspects are taken into account within the requirements by taking into account the interaction between the hearing protection user, the earplug and, where possible, the working environment in which the earplugs are likely to be used (see Annex ZA and EN 458).
