Noise characteristic values
Measurement conditions
The values stated are emission values and
are therefore not necessarily safe operating
values. Although there is a correlation be-
tween emission and immission levels, you
cannot reliably deduce from this whether
additional safety measures are required
or not. Factors which can inuence the
immission level currently at the worksta-
tion comprise the duration of the effects,
the characteristics of the work room, other
sources of noise etc., for example, the num-
ber of machines and adjacent operations.
The permissible values per workstation can
also vary from country to country. This in-
formation should nevertheless enable the
user to make a better estimation of dangers
and risks.
Sound level in dB
Idling LWA/ Processing LWA = 94/104 dB(A)
Sound level at the workplace in dB
Idling LpAeq/ Processing LpAeq = 83/93 dB(A)
A measurement uncertainty allowance K
= 4 dB applies to the mentioned emission
values.
Information on dust emission
The dust emission values measured in ac-
cordance with the „principles for testing
dust emission“ of the committee of experts
of wood are below 2 mg/m3. This means
that the TRK limit for wood dust which is
valid in the Federal Republic of Germany
will be permanently kept to if the machine
is connected to a properly working dust ex-
tractor with at least 20 m/s air speed.
Paramètres du bruit
Conditions de mesure
Les valeurs indiquées sont des valeurs
d’émission et, par conséquent, ne repré-
sentent pas nécessairement des valeurs
sans risques pour le lieu de travail. Bien
qu’il existe une corrélation entre les niveaux
d’émission et les niveaux d’immission, l’on
ne peut en déduire avec certitude si des
mesures de précaution supplémentaires
seront nécessaires ou non. Les facteurs
susceptibles d’inuences, la particularité
des locaux de travail, d’autres sources de
bruit, etc., comme par exemple, le nombre
de machines et des opérations effectuées
à proximité.
Les valeurs de bruit admissibles pour les
postes de travail peuvent également varier
d’un pays à l’autre. Néanmoins, cette infor-
mation a pour but de permettre à l’utilisa-
teur, d’effectuer une meilleure évaluation
des dangers et des risques.
Niveau de puissance acoustique indiqué
en dB
Marche à vide LWA/usinage LWA = 94/104
dB(A)
Niveau de pression acoustique au poste
de travail indiqué en dB
Marche à vide LpAeq/usinage LpAeq = 83/93
dB(A)
Un supplément d’incertitude de mesure K =
4 dB est valable pour les valeurs d’émission
citées
Données concernant les émissions de
poussière
Les valeurs d’émission de poussière mesu-
rées selon les „Principes du contrôle des
émissions de poussière (paramètre de
concentration) des machines à travailler le
bois“ de la commission des professionnels
du Bois, sont inférieures à 2 mg/m3. Ceci
permet de partir du principe que le raccor-
dement de la machine à un dispositif d’as-
piration de l’entreprise dont la vitesse de
circulation d’air s’élève au minimum à 20m/
sec, permettra de respecter durablement,
et de façon sûre, la valeur limite TRK en
vigueur en Allemagne pour la poussière de
bois.
