12、EN 60269-2:1995 ii BSI 24 September 2002 National foreword This British Standard has been prepared by Technical Committee PEL/32 and is the English language version of EN 60269-2:1995, including amendments A1:1998 and A2:2002. It is identical with IEC 60269-2:1986, including amendments 1:1995 and 2:
13、2001. Together with BS 88-2.2:1988, it supersedes BS 88-2:1975 which is withdrawn. 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 amendment
14、 1 is indicated by ?. Fuses within the scope of this standard are not sensitive to normal electromagnetic disturbances, and therefore no immunity tests are required. Significant electromagnetic disturbance generated by a fuse is limited to the instant of its operation. Provided that the maximum arc
15、voltages during operation in the type test comply with the requirements of the clause in this standard specifying maximum arc voltage, the requirements for electromagnetic compatibility are deemed to be satisfied.
