The text of document 17A(C0)249, future amendment 2 to IEC 56: 1987,
8、was submitted to the IEC-CENELEC parallel vote. As CENELEC TC 17A had decided to postpone the conversion of the HD into EN to the next edition of IEC 56, the combined text of HD 348 S5 and amendment 2:1995 to IEC 56: 1987 was approved by CENELEC as HD 348 S6 on 1995-07-04. The following dates were f

10、standards conflicting with the HD have to be withdrawn (daw) 1996-02-1 5 Annexes designated “normative“ are part of the body of the standard. In this standard, annexes AA, BB, CC, DD, EE, FF, GG, HH, JJ, ZA and ZB are normativ. Annexes ZA and ZB have been added by CENELEC. Page 3 HD 348 S6:1995 Rate

14、dition: National characteristic or practice that cannot be changed even over a long period, e.g. climatic conditions, electrical earthing conditions. If it affects harmonization, it forms part of the European Standard or Harmonization Document. For the countries in which the relevant special nationa
15、l conditions apply these provisions are normative, for other countries they are informative. Belgium Rated voltaaes To take account of a special national condition where there are appreciable discrepancies between actual network voltages and the next high test IEC rated voltages, two additional rate
