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

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
