Hearing protectors - General requirements - Part 3: Earmuffs attached to head protection and/or face protection devices
This document specifies requirements for construction, design, performance, marking and user information for earmuffs attached to head protection and/or face protection devices, hereinafter referred to as ‘mounted earmuffs’.
In particular, it specifies requirements regarding the sound attenuation of mounted 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 standard.
Because one model of earmuffs designed to be attached to head protection and/or face protection devices can be fitted to a number of other models and sizes of the carrier, this part of the standard sets out a series of physical and acoustic requirements for earmuffs when fitted to the specified model(s) or size(s) of head protection and/or face protection device.
All requirements apply to earmuffs fitted to one of the specified models or sizes of head protection and/or face protection device (the basic combination). An abbreviated set of requirements applies to the same model of earmuffs when fitted to the other specified models or sizes of head protection and/or face protection device (the supplementary combinations).
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).
Gehörschützer - Allgemeine Anforderungen - Teil 3: An Kopfschutz und/oder Gesichtsschutzgeräten befestigte Kapselgehörschützer
Dieses Dokument legt Anforderungen hinsichtlich Konstruktion, Gestaltung, Leistung, Kennzeichnung und Benutzerinformationen für an Kopfschutz und/oder Gesichtsschutz befestigte Kapselgehörschützer, im Folgenden bezeichnet als „befestigte Kapselgehörschützer“, fest.
Im Besonderen legt es Anforderungen bezüglich der Schalldämmung der befestigten Kapselgehörschützer fest, gemessen in Übereinstimmung mit EN ISO 4869 1:2018.
Dieses Dokument ist nicht anzuwenden für Kapselgehörschützer außerhalb des in dieser Norm definierten Bereichs von Kopfgrößen.
Weil ein Modell von Kapselgehörschützern zur Befestigung an Kopfschutz und/oder Gesichtsschutz an mehreren anderen Modellen und Größen der Trägervorrichtung befestigt werden kann, legt dieser Teil der Norm eine Reihe von physikalischen und akustischen Anforderungen fest, die zu erfüllen sind, wenn die Kapselgehörschützer an einem/einer oder mehreren bestimmten Modell(en) oder Größe(n) eines Kopfschutzes und/oder Gesichtsschutzes angebracht sind.
Alle Anforderungen sind anzuwenden für Kapselgehörschützer, die an einem der angegebenen Modelle oder Größen des Kopfschutzes und/oder Gesichtsschutzes befestigt werden (die Basiskombination). Ein verkürzter Satz an Anforderungen gilt für dasselbe Kapselgehörschützer-Modell, wenn es an die anderen angegebenen Modelle oder Größen des Kopfschutzes und/oder Gesichtsschutzes befestigt wird (die Zusatzkombinationen).
Ergonomische Aspekte werden innerhalb der Anforderungen durch die Einbeziehung der Wechselwirkung zwischen dem Gehörschutzbenutzer, dem Gehörschutz und, wo möglich, der Arbeitsumgebung, in dem der Gehörschutz wahrscheinlich benutzt wird, berücksichtigt (siehe Anhang ZA und EN 458).
Protecteurs individuels contre le bruit - Exigences générales - Partie 3 : Serre-tête montés sur dispositifs de protection de la tête et/ou du visage
Le présent document spécifie les exigences en matière de construction, de conception, de performances, de marquage et d'informations destinées à l'utilisateur des serre-tête montés sur des dispositifs de protection de la tête et/ou du visage, ici désignés sous l'appellation « serre-tête montés ».
Il spécifie en particulier les exigences relatives à la déclaration de l'affaiblissement acoustique des serre-tête montés, mesuré conformément à l'EN ISO 4869-1:2018.
Le présent document ne s'applique pas aux serre-tête dont la taille n'appartient pas à la gamme de tailles définie dans la présente norme.
Du fait qu'un même modèle de serre-tête conçu pour être monté sur des dispositifs de protection de la tête et/ou du visage peut être fixé sur un certain nombre de modèles ou tailles de dispositifs de protection de la tête et/ou du visage, la présente partie de la norme définit une série d'exigences physiques et acoustiques pour le serre-tête lorsqu’il est monté sur le ou les modèle(s) ou taille(s) spécifié(s) de dispositifs de protection de la tête et/ou du visage.
Les exigences s'appliquent en totalité à la combinaison de base, c'est-à-dire aux serre-tête montés sur l'un des modèles ou l'une des tailles spécifiés de dispositif de protection de la tête et/ou du visage. Elles s'appliquent en partie seulement à la/aux combinaison(s) supplémentaire(s), c'est-à-dire aux serre-tête du même modèle mais montés sur les autres modèle(s) ou taille(s) de dispositifs de protection de la tête et/ou du visage qui sont spécifiés.
Dans les exigences spécifiées, les aspects ergonomiques sont abordés par la prise en compte de l'interaction entre l'utilisateur, l'équipement et, quand cela est possible, l'environnement de travail dans lequel l'équipement est susceptible d'être utilisé (voir l'Annexe ZA et l'EN 458).

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 352-3 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 −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 earmuffs attached to head protection and/or face protection devices (mounted
earmuffs).
The sizing requirements enable the majority of the user population to be fitted satisfactorily by
“medium size range” mounted earmuffs. Individuals with other sizes can be accommodated by “small
size range” or “large size range” mounted 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 provided by the mounted earmuffs
(measured in accordance with EN ISO 4869-1) in order to assist users in selecting the most appropriate
model of mounted 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 mounted 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 attached to head protection and/or face protection devices, hereinafter
referred to as ‘mounted earmuffs’.
In particular, it specifies requirements regarding the sound attenuation of mounted 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
standard.
Because one model of earmuffs designed to be attached to head protection and/or face protection
devices can be fitted to a number of other models and sizes of the carrier, this part of the standard sets
out a series of physical and acoustic requirements for earmuffs when fitted to the specified model(s) or
