This European Standard specifies requirements for construction, design, performance, marking and user information for earmuffs attached to head protection and/or face protection devices, hereinafter referred to as ‘mounted earmuffs’.
In particular, it specifies the sound attenuation of mounted earmuffs, measured in accordance with EN ISO 4869-1.
Because one model of earmuffs designed to be attached to head protection and/or face protection devices can be fitted to a number of other models and sizes, this part of the standard sets out a series of physical and acoustic requirements for earmuffs when fitted to the specified model(s) or size(s) of head protection and/or face protection device.
All requirements apply to earmuffs fitted to one of the specified models or sizes of head protection and/or face protection device (the basic combination). An abbreviated set of requirements apply applies to the same model of earmuffs when fitted to the other specified models or sizes of head protection and/or face protection device (the supplementary combinations).
Information shall be given on the range of models of carriers tested with the earmuffs which satisfies this European Standard.
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 EN 458).
