prEN 352-1:2018 (E) 3 European foreword This document (prEN 352-1:2018) has been prepared by Technical Committee CEN/TC 159 “Hearing protectors”, the secretariat of which is held by DIN. This document is currently submitted to the CEN Enquiry. This document will supersede EN 352-1:2002. This document has been prepared under a standardization request given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. oSIST prEN 352-1:2018

prEN 352-1:2018 (E) 4 Introduction This document sets requirements for personal hearing protection devices in relation to Regulation (EU) 2016/425 on personal protective equipment. The particular requirement in relation to the ability of hearing protectors to reduce noise below daily limit levels is addressed in the standard by requiring the sound attenuation of the hearing protectors, measured in accordance with EN ISO 4869-1, to be not less than a specified minimum. Further, by requiring that the measured sound attenuation be declared, the selection of suitable hearing protectors for individual circumstances may be undertaken according to established practice. EN 352-1 is part of a family of standards describing product requirements for hearing protectors: — EN 352-1, Hearing protectors — General requirements — Part 1: Earmuffs — EN 352-2, Hearing protectors — General requirements — Part 2: Earplugs — EN 352-3, Hearing protectors — General requirements — Part 3: Earmuffs attached to head protection and/or face protection devices — EN 352-4, Hearing protectors — Safety requirements — Part 4: Level-dependent earmuffs — EN 352-5, Hearing protectors — Safety requirements — Part 5: Active noise reduction earmuffs — EN 352-6, Hearing protectors — Safety requirements — Part 6: Earmuffs with safety-related audio input — EN 352-7, Hearing protectors — Safety requirements — Part 7: Level-dependent earplugs — EN 352-8, Hearing protectors — Safety requirements — Part 8: Entertainment audio earmuffs — EN 352-9, Hearing protectors — Safety requirements — Part 9: Earplugs with safety-related audio input — EN 352-10, Hearing protectors — Safety requirements — Part 10: Entertainment audio earplugs Test methods for these requirements for all types of hearing protectors are described in the following standards: — EN 13819-1, Hearing protectors — Testing — Part 1: Physical test methods — EN 13819-2, Hearing protectors — Testing — Part 2: Acoustic test methods — EN 13819-3, Hearing protectors — Testing — Part 3: Supplementary acoustic test methods An associated standard EN 458 covers selection, use, care and maintenance of hearing protection. The parts of EN 352, other than parts 1, 2 and 3, cover the performance of functions additional to passive hearing protection. Hearing protectors which incorporate one or more of these functions are subject to the requirements and tests of each of the relevant parts of EN 352, including parts 1, 2 or 3, as appropriate. The requirements of this European Standard are concerned primarily with the physical and acoustic performance of the earmuffs. The sizing requirements enable the majority of the industrial population to be fitted satisfactorily by "medium size range” earmuffs. Populations of other sizes may be accommodated by ”small size range" oSIST prEN 352-1:2018

prEN 352-1:2018 (E) 5 or "large size range" earmuffs, which are required to be accompanied by information regarding the range of sizes which they are designed to fit. The standard also calls for the values of sound attenuation afforded by the earmuffs (measured in accordance with EN ISO 4869-1) in order to assist purchasers in selecting the most appropriate model of earmuffs for their needs. Minimum values of sound attenuation are also specified. A maximum variability in insertion loss, measured objectively after a series of performance tests, is specified. The objective test method only facilitates the making of comparative measurements, and the insertion loss values obtained will differ from the measured sound attenuation values. The latter, which requires the earmuffs to be tested whilst being worn by human test subjects, is regarded as providing the reference test method for the measurement of the acoustic performance of hearing protectors. oSIST prEN 352-1:2018

prEN 352-1:2018 (E) 6 1 Scope This document specifies requirements for construction, design, performance, marking and user information for earmuffs. In particular, it specifies the sound attenuation of the earmuffs, measured in accordance with EN ISO 4869-1. This document does not deal with earmuffs for attachment to head protection and/or face protection devices. Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the user, the device and where possible the working environment in which the device is likely to be used (see Annex ZA and EN 458). 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
