Specifies constructional, design and performance requirements, test methods, marking requirements and user information for ear-muffs when fittid to an industrial safety helmet. It calls for information to be made available concerning the sound attenuation characteristics of the ear-muffs measured in accordance with EN 24869-1:1992, and defines a minimum level of attenuation required for compliance with this specification. Because one model of ear-muffs designed to be attached to an industrial safety helmet can be fitted to a number of helmet models and sizes, this part of the standard sets out a series of mechanical and acoustic tests intended to assess performance ot the ear-muffs when fitted to the specified model(s) or sizes of helmet.
