support a relevant ER of the Machinery normal use taking into account the manufacturer's instructions It also covers any reasonably foreseeable Directive 98/37/EC misuse of the machinery and takes into account the way in which electromagnetic phenomena can affect the safe operation of commercial electric dishwashing machines A commercial electric conveyor dishwashing machine that complies with the text of this European Standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by these requirements This European Standard takes into account the requirements of HD 60364-1 as far as possible so that there is compatibility with the wiring rules when the machinery is connected to the supply mains However, national wiring rules may differ Pressurized components incorporated in machines within the scope of this European Standard are pressure equipment that is classified no higher than category I of the Pressure Equipment Directive (93/68/EU) According to Article 1, item 3.6 of the Pressure Equipment Directive, this equipment is excluded from its scope The requirements of Annex CC of this European Standard not support a relevant ESHR of the Machinery Directive 2006/42/EC.

Noise DD.1 Noise reduction Noise reduction shall be an integral part of the design process thus specifically taking into account measures at source as given in EN ISO 11688-1 The success of the applied noise reduction measures is assessed on the basis of the actual noise emission values (see DD.2) in relation to other appliances of the same family DD.2 Noise test code DD.2.1 Emission sound pressure level determination The A-weighted emission sound pressure level shall be measured in accordance with EN ISO 11201 grade or EN ISO 11204 grade If it is not possible to comply with the requirements of grade EN ISO 11204 grade shall be applied In this case, the test report shall state the reasons why it was not possible to apply the grade method The microphone positions to determine the emission sound pressure level are shown in Figure DD.101 describing possible positions of the operator at the inlet and outlet section of the appliance The highest emission sound pressure level determined at the different positions shall be taken for the declaration The distance to the appliance is 0,2 m The microphone heights shall be 1,55 m ± 0,05 m The measurement time at each position shall be at least 15 s Figure DD.101 – Microphone positions for determining the emission sound pressure level DD.2.2 Sound power level determination If it is required to determine the A-weighted sound power level, it shall be measured in accordance with EN ISO 3744 or EN ISO 9614-2, grade When applying EN ISO 3744 or EN ISO 9614-2 the parallelepiped measurement surface shall be used If grade cannot be applied, EN ISO 3746 or EN ISO 9614-2, grade shall be used In this case, the test report shall state the reasons why it was not possible to apply the grade method. 13 EN 50416:2005/A1:2015 (E) - 35 - BS EN 50416:2005+A1:2015 EN 50416:2005+A1:2015(E) DD.2.3 Installation conditions The tests are carried out with the appliance placed on a normal plane sound reflecting floor Care shall be taken that any electrical connections, piping or air ducts connected to the appliance not significantly contribute to the noise emission of the appliance The installation conditions of the appliance shall be identical for determining both the emission sound pressure level and the sound power level DD.2.4 Operating conditions The appliance is supplied at rated voltage and operated under the conditions of normal operation as specified in Clause 11 The operating conditions shall be identical for the determination of both sound power levels and emission sound pressure levels at specified positions DD.2.5 Measurement uncertainties The total measurement uncertainty of the noise emission values determined according to this European Standard is depending on the standard deviation σR0 given by the applied noise emission measurement method and the uncertainty associated with the instability of the operating and mounting conditions σomc The resulting total uncertainty is then calculated from σ tot = σR2 + σomc The upper bound value of σR0 is about 1,5 dB for the grade measurement methods dealing with the determination of the emission sound pressure level or the sound power level NOTE For machines with a rather constant noise emission a value of 0,5 dB for σomc can apply In other cases, e.g a large influence of the material flow into and out of the machine or material flow that varies in an unpredictable manner, it is possible that a value of dB can be more appropriate Methods to determine σomc are described in the basic measurement standards The expanded measurement uncertainty U, in decibels, shall be calculated from U = k σtot, with k the coverage factor NOTE The expanded measurement uncertainty depends on the degree of confidence that is desired For the purpose of comparing the result with a limit value, it is appropriate to apply the coverage factor for a one-sided normal distribution In that case, the coverage factor k = 1,6 corresponds to a 95 % confidence level Further information is given in EN ISO 4871 The expanded measurement uncertainty U is denoted as K in EN ISO 4871 NOTE The expanded measurement uncertainty as described in this European Standard does not include the standard deviation of production that is used in EN ISO 4871 for the purpose of making a noise declaration for batches of machines DD.2.6 Information to be recorded The information to be recorded covers all the technical requirements of this noise test code Any deviations from this noise test code or from the basic standards upon which it is based are to be recorded together with the technical justification for such deviations. 14 BS EN 50416:2005+A1:2015 EN 50416:2005+A1:2015(E) - 36 - EN 50416:2005/A1:2015 (E) DD.2.7 Information to be reported The information to be given in the test report shall include what the manufacturer requires to prepare a noise emission declaration or what the user requires to verify the declared values Thus, the following information shall be included: reference to the noise test code and the basic noise emission standards used; description of the installation and operation conditions used; location of the workstation(s) or other specified positions; the noise emission values obtained It shall be confirmed that all requirements of the noise test code have been fulfilled, or, if this is not the case, any unfulfilled requirements shall be identified Deviations from the requirements shall be stated and technical justification for the deviations shall be given DD.2.8 Declaration and verification of noise emission values The declaration of the noise emission values shall be made as a dual number noise emission declaration according to EN ISO 4871 It shall declare the emission sound pressure level LpA and the respective uncertainty KpA and if required additionally the sound power level LWA with its uncertainty KWA The noise declaration shall state that the noise emission values have been obtained according to this noise test code Any deviations from this noise test code or from the basic standards upon which it is based shall be clearly indicated NOTE KpA and KWA are expected to be 2,5 dB for grade and dB for grade measurements Additional noise emission values may also be given in the declaration If undertaken, verification of the noise emission values shall be conducted according to EN ISO 4871, using the same mounting and operating conditions as those used for the initial determination. 15 EN 50416:2005/A1:2015 (E) - 37 - BS EN 50416:2005+A1:2015 EN 50416:2005+A1:2015(E) Replace Annex ZE and Annex ZF of
