2、he authority of the Standards Policy and Strategy Committee on 31 October 2005 BSI 2007 ISBN 978 0 580 59193 8 National foreword This British Standard is the official UK implementation of EN 60034-9:2005, incorporating amendment A1:2007. It is identical with IEC 60034-9:2003, incorporating amendment
3、 1:2007. It supersedes BS EN 60034-9:1998 which will be withdrawn on 1 March 2008. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. Tags indicating changes to IEC text carry the number of the IEC amendment. For example, text altered by IEC amendmen
4、t 1 is indicated in the text by !“. The CENELEC common modifications have been implemented at the appropriate places in the text and are indicated by tags (e.g. ). The UK participation in its preparation was entrusted to Technical Committee PEL/2, Rotating electrical machinery. A list of organizatio

The use of a sound power level, which

Sound power levels provide a measure of radiated energy and have advantages in acoustic analysis and
