BS EN 415-9:2009EN 415-9:2009 (E) 4 1 Scope This standard specifies all the information necessary to carry out efficiently and under defined conditions the determination, information and verification of airborne noise emission from packaging machine cove

23、red by EN 415-1. This measurement method specifies procedures for the determination of emission sound pressure levels at work station, at other specified positions and the sound power level on the basis of both the sound pressure level method and the sound intensity method. It also specifies install

24、ation and operating conditions. This standard applies to machines covered by EN 415-1 as well as for any other packaging machine which are not covered by any other specific noise test code as well as for machines being part of packaging line. In such cases, all information relating to the assembly,

25、installation and to the operating conditions as well as the arrangement of the work station shall be recorded and reported in the test report. Noise emission characteristics include the following data: emission sound pressure level at work station and at other specified positions; sound power emitte

26、d by machine. Both can be used: to determine the noise emitted by machine; to inform on the noise emitted by the machine; to verify the noise emitted by the machine. Noise emission values permit comparison of packaging machines on the market. The use of this standard ensures the reproducibility of t

27、he determination of the characteristic noise emissions values within specific limits which will be determined by the grade of accuracy of the noise emission measuring method used. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、 1 Very large machines BS EN 415-9:2009EN 415-9:2009 (E) 6 4 Description of machine under test The machines specified in this standard are listed in EN 415-1, and, for machines not listed, the manufacturer shall describe them in the test report. The packaging machine described by Annex D (informativ

40、e) of this document includes any equipment, electric cabinet and optional devices, delivered with the machines, which contribute to the overall noise emission. 5 Determination of the emission sound pressure level at work station 5.1 Sound pressure level measurement at work station The A-weighted emi

41、ssion sound pressure level at the workstation LpAshall be determined in compliance with EN ISO 11201, EN ISO 11202, EN ISO 11203 or EN ISO 11204. The appropriate standard shall be selected by using Annex A (normative). The positions of the work stations and of other specified positions shall be defi

42、ned by the manufacturer in compliance with Annex D (informative). In all cases the microphone shall be located directly above the reference point on the ground plane on which the operator normally stands, at a distance of 1 m from the machine, at a nominal height of 1,6 m without an operator being p

43、resent, and the microphone shall be directed towards the machine. The emission sound pressure level at the work station and at other specified positions shall be determined, over a typical period of operation of the machine under test. The measurement time shall be at least 30 s and represent a mini

44、mum of 5 cycles. For steady noise further measurement time can be reduced as stable value has been reached according to the characteristics of the instrument used. For unsteady noise levels it is important to specify carefully the period of observation; in particular an appropriate measuring period

45、shall be selected and stated in the test report. For machines operating in a production line noise measurement shall be carried out after commissioning. 5.2 Background noise correction K1Details about the evaluation of quantities related to the determination of the background noise correction K1are

47、1 General method Sound power level shall be determined in compliance with one of the following standards: EN ISO 3744, EN ISO 9614-2, EN ISO 3746, EN ISO 3747. See Annex C (normative) for guidance on the selection of the standard. BS EN 415-9:2009EN 415-9:2009 (E) 7 6.2 Alternative method for very l

48、arge machines For very large machines, instead of the sound power level, it is permissible to determine and declare emission sound pressure levels at specified measurement points around the machine. Such points shall be specified along a path around the machine at a height of 1,6 m above the ground

49、plane on which the operator normally stands and at a distance of 1 m from the machine. 7 Assembly and installation conditions The machine shall be assembled and installed in compliance with the manufacturers instructions. If several modes are possible, a typical condition shall be recommended by the manufacturer and a detailed description shall be stated in the test report. The assembling and installation condition
