Acoustics - Noise test code for fastener driving tools - Engineering method
This standard applies to fastener driving tools. The noise created by fastener driving tools directly affecting the surrounding environment (noise emission) should calculated in a uniform procedure enabling comparison of the final results. This standard contains provisions concerning the execution of the measurement of airborne noise in the vicinity of fastener driving tools and the measurement of emission sound pressure levels at the work station under defined operating conditions.
The determination of the noise emission levels of fastener driving tools in accordance with this standard is valid for all actuating systems in accordance with EN 792-13.
The results can be used to compare the noise emissions of different fastener driving tools.
NOTE The special conditions at the work place (e.g. shape and foundation of the workpiece, quantity and frequency of the driving processes) can influence the noise emission to an important degree.
Akustik - Geräuschmessverfahren für Eintreibgeräte - Verfahren der Genauigkeitsklasse 2
Diese Norm gilt für Eintreibgeräte. Das Geräusch, welches von Eintreibgeräten direkt in die Umgebung
abgestrahlt wird (Geräuschemission), soll nach einem einheitlichen Verfahren ermittelt werden, so dass die
Ergebnisse vergleichbar sind. Diese Norm enthält Festlegungen über die Durchführung der Messung von
Luftschall, der von Eintreibgeräten in die Umgebung abgestrahlt wird, sowie für die Messung des Emissions-
Schalldruckpegels am Arbeitsplatz unter festgelegten Betriebsbedingungen.
Die Bestimmung der Geräuschemissionswerte von Eintreibgeräten nach dieser Norm gilt für alle Auslösesysteme
entsprechend EN 792-13.
Die Ergebnisse können dazu dienen, die Geräuschemission von verschiedenen Eintreibgeräten zu
vergleichen.
ANMERKUNG Die am jeweiligen Arbeitsplatz vorhandenen Bedingungen (z. B. Werkstückgestaltung, Werkstückauflage,
Zahl und zeitlicher Verlauf der Eintreibvorgänge) können die Geräuschemission wesentlich beeinflussen.
Acoustique - Code d'essai acoustique pour les machines à enfoncer les fixations - Méthode d'expertise
Cette norme s'applique aux machines à enfoncer les fixations. Il convient de calculer le bruit créé par les machines
à enfoncer les fixations affectant directement l'environnement (émission sonore) avec un même et seul mode
opératoire permettant une comparaison des résultats finaux. Cette norme définit les conditions d'exécution du
mesurage du bruit aérien au voisinage des machines à enfoncer les fixations et de mesurage des niveaux de pression
acoustique d'émission au poste de travail dans des conditions de fonctionnement définies.
La détermination des niveaux d’émission sonore des machines à enfoncer les fixations, conformément à la présente
norme, est valide pour tous les systèmes de commande conformément à l’EN 792-13.
Les résultats peuvent être utilisés pour comparer l'émission sonore de différentes machines à enfoncer les fixations.
NOTE Les conditions particulières de fonctionnement au poste de travail (par exemple la forme de la pièce travaillée
et la façon dont elle est tenue, la quantité et la fréquence des enfoncements) peuvent influencer l'émission sonore de
façon importante.

EN 12549:1999+A1:2008 (E) 5 Introduction This noise test code describes methods for determining and presenting the acoustical characteristics of fastener driving tools. The EC Machinery Directive prescribes that noise emission values for the machines in a defined process shall be stated. The manufacturer of fastener driving tools must indicate the operating conditions during the noise measurement and what methods have been used for the measurement. 1 Scope This standard applies to fastener driving tools. The noise created by fastener driving tools directly affecting the surrounding environment (noise emission) should calculated in a uniform procedure enabling comparison of the final results. This standard contains provisions concerning the execution of the measurement of airborne noise in the vicinity of fastener driving tools and the measurement of emission sound pressure levels at the work station under defined operating conditions.
The determination of the noise emission levels of fastener driving tools in accordance with this standard is valid for all actuating systems in accordance with EN 792-13. The results can be used to compare the noise emissions of different fastener driving tools. NOTE The special conditions at the work place (e.g. shape and foundation of the workpiece, quantity and frequency of the driving processes) can influence the noise emission to an important degree. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

EN 12549:1999+A1:2008 (E) 6 3 Definitions For the purposes of this standard, the following definitions apply: 3.1 A-weighted single-event emission sound pressure level, LpA,1s in dB:
A-weighted and time-integrated emission sound pressure level of an isolated single sound event of specified duration T (or specified measurement time T), related to T0 = 1 s; it is given by the following equation: LpA,1 s = 10 lg[ 10T ∫T0202)(ptp dt ] dB = LpAeq,T + 10 lg TT0
dB
…(1) The reference sound pressure is p0 = 20 µPa. 3.2 A-weighted single-event sound power level, LWA,1s in dB: A-weighted sound power level determined from measurements of the single-event sound pressure level. 3.3 C-weighted peak emission sound pressure level, LpC,peak in dB: The C-weighted peak emission sound pressure level of a test object, determined in accordance with EN ISO 11201 at the work station. 3.4 Fastener driving tool See EN 792-13. 4 Description of fastener driving tools Fastener driving tools are handheld power tools in which energy is applied in a linear movement to inserted fasteners for the purpose of driving. The design of these fastener driving tools is such that in normal circumstances they may be carried by one person and are handheld during the driving process. NOTE Fastener driving tools are named e.g. nailers, staplers, tackers, pinners. The energy required for the driving process can be drawn e.g. from compressed air, electrical current, combustible gases, tension springs. Fasteners may be e.g. nails, staples, pins, brads, corrugated fasteners and screws used as nails. The frequency of the driving processes with a fastener driving tool varies in time according to the operation purpose (e.g. 500 driving processes per day may be carried out with a big fastener driving tool against 20 per second with a small one). The time duration of one driving process is normally in a range of 0,1 s or shorter. 5 Sound power level determination 5.1 Basic International Standards to be used If it is required to determine the sound power level, basic sound power measurement standards shall be used, such as EN ISO 3744. SIST EN 12549:2000+A1:2008
EN 12549:1999+A1:2008 (E) 7 The sound power level shall be given as A-weighted sound power level in dB. The reference sound power is 1pW (1 pW = 10-12 W). 5.2 Measurement procedure 5.2.1 Measurement surface The measurement surface is a hypothetical cube on which the measurement positions are located and which envelops the fastener driving tool (see figure 1). Exception: Position O for measuring the A-weighted single-event emission sound pressure level at work station. The measurement surface ends at floor level, which is to be regarded as a sound reflecting periphery. The height of the centre point of the fastener driving tool above the ground shall be (1,00 ± 0,10) m. The centre point is located on the driving axis at half of the height of the fastener driving tool. NOTE Because a fastener driving tool is of small size the centre point of a fastener driving tool is used instead of the surface. 5.2.2 Measurement distance The measurement distance shall be 1,00 m from the centre point of the fastener driving tool (see figure 1). 5.2.3 Measurement positions The location of the nine measurement positions i = 1, 2, ., 9 shall be that of figure 1.
