EQV: Når publikationen teknisk er i overensstemmelse med en given publikation, men præsentationen er ændret. NEQ: Når publikationen teknisk eller præsentationsmæssigt ikke er i overensstemmelse med en given standard, men udarbejdet på baggrund af denne. MOD: Når publikationen er modificeret i forhold til en given publikation.
EUROPEAN STANDARD EN 60034-9 NORME EUROPÉENNE EUROPÄISCHE NORM May 2005 ICS 29.160 Supersedes EN 60034-9:1997 English version Machines électriques tournantes Partie 9: Limites de bruit (CEI 60034-9:2003, modifiée) Rotating electrical machines Part 9: Noise limits (IEC 60034-9:2003, modified) Drehende elektrische Maschinen Teil 9: Geräuschgrenzwerte (IEC 60034-9:2003, modifiziert) This European Standard was approved by CENELEC on 2005-03-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions. CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 60034-9:2005-2 - Foreword The text of the International Standard IEC 60034-9:2003, prepared by IEC TC 2, Rotating machinery, together with the common modifications prepared by the Technical Committee CENELEC TC 2, Rotating machinery, was submitted to the formal vote and was approved by CENELEC as EN 60034-9 on 2005-03-01. This European Standard supersedes EN 60034-9:1997. It includes the following significant technical changes: it reduces the no-load noise limits for single-speed, cage-induction motors according to Table 2; it provides informative guidance on the measurement surface to be used during some tests, a method for the determination of an average sound pressure level, an indication of "uncertainty" based upon the category of test procedure. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2006-03-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2008-03-01 Annex ZA has been added by CENELEC.
- 3 - EN 60034-9:2005 Endorsement notice The text of the International Standard IEC 60034-9:2003 was approved by CENELEC as a European Standard with agreed common modifications as given below. COMMON MODIFICATIONS 4 Methods of measurement 4.1 Replace the note by: NOTE It is recommended that the parallelepiped method be used for all electrical machines. 5 Test conditions 5.2 Replace item b) by: b) Machines shall be tested in their operating position and in case of designs for several distinct speeds or for a speed range at that speed which generates the greatest noise. Delete item f) and rename item g) to become item f). 7 Determination of sound pressure level Replace the first paragraph by: Sound pressure levels are not required as part of this standard. If requested, an A-weighted sound pressure level may be determined from the test readings (see 4.1). Only if tested sound pressure values are not available an A-weighted sound pressure level may be determined from the sound power level as follows: Replace the last paragraph by: S is the area in m² of a parallelepiped surface enveloping the machine at a distance from the machine of 1 m according to ISO 3744. Delete the two columns headed "Shaft height" and "Surface area, S".
