This document specifies requirements for construction, design, performance, marking and user information for earmuffs.

In particular, it specifies requirements regarding the sound attenuation of the earmuffs, measured in accordance with EN ISO 4869?1:2018.

The document does not apply to earmuffs outside the size range of headsizes as defined in this standard.

This document does not apply to earmuffs for attachment to head protection and/or face protection devices.

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 (see Annex ZA and EN 458).
