DIN EN 352-1:2018-08

DIN EN 352-1 specifies requirements for construction, design, performance, marking and user information for earmuffs. In particular, it specifies the sound attenuation of the earmuffs, measured in accordance with DIN EN ISO 4869-1. This European Standard does not deal with earmuffs for attachment to a head protection and/or face protection devices. Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the wearer, the device and where possible the working environment in which the device is likely to be used (see Annex ZA and DIN EN 458).
