3、580 27750 X National foreword This British Standard is the English language version of EN 61185:1997. It is identical with IEC 61185:1992 including Amendment 1:1995. The UK participation in its preparation was entrusted to Technical Committee EPL/51, Transformers, inductors, magnetic components and

5、nts and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of ti

The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or using the “Find” facility of the B
