European foreword
This document (EN 352-1:2020) has been prepared by Technical Committee CEN/TC 159 “Hearing
protectors”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2021, and conflicting national standards shall be
withdrawn at the latest by November 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document will supersede EN 352-1:2002.
The technical changes between this document and the previous edition of this European Standard are
listed in Annex A.
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 Regulation(s).
For relationship with EU Regulation(s), see informative Annex ZA, which is an integral part of this
document.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
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 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 can 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 352-4 to EN 352−10, in
addition to that of parts 1, 2 or 3, as appropriate.
The requirements of this document are concerned primarily with the physical and acoustic
performance of the earmuffs.
The sizing requirements enable the majority of the user population to be fitted satisfactorily by
“medium size range” earmuffs. Individuals with other sizes can be accommodated by ”small size range”
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 document also calls for the values of sound attenuation provided by the earmuffs (measured in
accordance with EN ISO 4869-1) in order to assist users 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 method to
determine the sound attenuation values, 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.
1 Scope
This document specifies requirements for construction, design, performance, marking and user
information for earmuffs.
In particular, it specifies requirements regarding the sound attenuation of the earmuffs, measured in
accordance with EN ISO 4869-1:2018.
The document does not apply to earmuffs outside the size range of headsizes as defined in this
document.
This document does not apply to 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).
