CE EN 352-2 2002 is the Personal Protective Equipment Standard which applies to earmuffs, ear plugs and ear defenders for use in areas with noise levels which could be damaging to hearing and lead to noise-induced hearing loss.

There are particular requirements for design, construction, marking and instructions and user information. Sound attenuation abilities are highly important and are measured according to EN 24869-1.
