Compliance of eachindividual motorized chain saw with the approved type shall beshown by a noise logo affixed to the tool and by a certificatewhich is to accompany the motorized chain saw in questionexceeds the maximum permitted noise capacity level uponinspection. The system of type approval is in keeping with thesystem applicable in a number of EC directives governing noiseoutput of certain appliances.
