28、on 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 i

29、ndicate 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

30、 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 c

31、onditions. 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 condition

32、s 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. The

38、ified duration T (or specified measurement time T), related to T0= 1 s; it is given by the following equation: LpA,1 s= 10 lg 10TT0202)(ptpdt dB = LpAeq,T+ 10 lg TT 0dB (1) The reference sound pressure is p0= 20 Pa. 3.2 A-weighted single-event sound power level, LWA,1sin dB: A-weighted sound power l

40、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

41、 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.

42、 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 se

43、cond 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, suc

44、h as EN ISO 3744. DIN EN 12549:2008-12 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 = 10-12W). 5.2 Measurement procedure 5.2.1 Measurement surface The measurement surface is a hypothetical cube on which

45、 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 reflectin

46、g 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 d

47、riving 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. Dime

48、nsions in metres Measurement positions 0 Measurement position at the work station (near the operators ear) Figure 1 Location of the measurement positions for fastener driving tools DIN EN 12549:2008-12 EN 12549:1999+A1:2008 (E) 8 5.2.4 Measurement of the A-weighted single-event sound pressure level

49、The A-weighted single-event sound pressure level of one driving process LpA,1sshall be measured five times at each measurement position i. The arithmetic mean of the five values shall be determined for each measurement position i and is denoted LpA,1s, i (with i = 1, 2, .9). NOTE In the case of fastener driving tools which can be actuated only by continuous actuation of the driving process, the A-weighted sound pressure level LpA,ishould be measured five times for the same time duration (e.g. 5 s) and the number of driving
