What Is CE EN 352-2 2002?
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.
Tested to CE EN 352-2 2002, ZenPlugs PPE Ear Plugs meet the stringent criteria laid out for ear plugs by CEN's Technical Committee. If you are wondering what is CE EN 352-2 2002, the criteria and results are as follows;
Markings. Packaging and product include information on whether disposable or re-usable, extensive fitting instructions and left and right differentiation. The European Standard EN 352-2:2002 is also listed. The sound attenuation values are included, as are cleaning and disinfection instructions. Warnings are included that instructions must be followed correctly and plugs always worn in noisy environments. Pass.
Attenuation. Sound attenuation was assessed in lab conditions by human subjects. SNR = 22. Pass.
