This part of the Standard specifies constructional, design and performance requirements, methods of test, marking requirements and user information for ear-muffs attached 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 ISO/DIS 4869-1, and defines a minimum level of attenuation required for compliance with this specification. Because ear-muffs designed to be attached to an industrial safety helmet may be capable of being fitted to a number of helmet types, this part of the standard sets out a series of mechanical tests intended to assess compatibility of the ear-muffs and helmet. Attenuation testing to ISO/DIS 4869-1 is then only undertaken on one of the compatible combinations and on any further combinations with significant differences in equivalent headband force or insertion loss data. For type approval tests in compliance with this standard the industrial safety helmets specified by the car-muffs manufacturer shall comply with prEN 397. Information on the range of industrial safety helmet types tested with the ear-muffs is required to be made available. This part of the Standard does not deal with the performance of electronic devices which may be incorporated within ear-muffs, or amplitude sensitive ear-muffs.
