Hearing protectors - General requirements - Part 3: Ear-muffs attached to an industrial safety helmet
This part of the standard specifies requirements for construction, design, performance, marking and user information for ear-muffs fitted to an industrial helmet which complies with EN 397, Industrial safety helmets. In particular, it calls for the sound attenuation of the ear-muffs, measured in accordance with EN 24869-1, to be declared and to be not less than a specified minimum. The requirements of this standard are intended to take account of the ergonomic interaction between the wearer, the device and where possible the working environment in which the device is likely to be used (see Annex ZA, of this standard and EN 458).
Gehörschützer - Allgemeine Anforderungen - Teil 3: An Industriehelmen befestigte Kapselgehörschützer
Dieser Teil der Norm legt Anforderungen hinsichtlich Konstruktion, Gestaltung, Leistung, Kennzeichnung und Benutzerinformationen für Kapselgehörschützer fest, die an Industrieschutzhelmen befestigt sind, die EN 397, Industrieschutzhelme, entsprechen. Im besonderen fordert sie die Angabe der durch die Kapselgehörschützer geleisteten nach EN 24869-1 gemessenen Schalldämmung einen festgelegten Mindestwert nicht unterschreiten darf. Die Anforderungen dieser Norm haben das Ziel, die ergonomische Wechselwirkung zwischen dem Benutzer, dem Gerät und wo möglich der Arbeitsumgebung, in der das Gerät voraussichtlich benutzt wird, zu berücksichtigen (siehe Anhang ZA dieser Norm und EN 458).
Protecteurs individuels contre le bruit - Exigences générales - Partie 3: Serre tête montés sur casque de sécurité industriel
La présente partie de la norme spécifie les exigences en matière de construction, de conception, de performances et de marquage des serre-tête montés sur casque de sécurité industriel conforme à l'EN 397 ainsi que les informations destinées à l'utilisateur.
Elle prescrit en particulier une déclaration de l'affaiblissement acoustique des serre-tête montés sur casque, mesuré conformément à l'EN 24869-1.
Du fait qu'un même modèle de serre-tête peut être monté sur différents modèles ou tailles de casques de sécurité industriel, la présente partie de la norme définit une série d'exigences physiques et acoustiques fonction du modèle ou de la taille de casque sur lequel le serre-tête est monté.
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 de casque spécifiés, et en partie seulement à la combinaison supplémentaire, c'est-à-dire aux serre-tête du même modèle mais montés sur des casques de modèle ou de taille autre que ceux qui sont spécifiés.
Il est exigé de mettre à disposition les informations sur la gamme de casques testés avec les serre-tête, et dont les combinaisons satisfont à la présente norme.
Les aspects ergonomiques sont abordés en tenant compte de l'interaction entre la personne qui porte les serre-tête, l'appareil et, quand cela est possible, l'environnement de travail dans le lequel l'appareil est susceptible d'être utilisé (voir l'annexe ZA et l'EN 458).
