Page 2 EN 50186-2:1998 BSI 05-1999 Foreword This European Standard was prepared by the CENELEC BTTF 62-4, Live-line washing systems for power installations with rated voltages above 1 kV. The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50186-2 on 1997-03-11. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement(dop) 1999-03-01 latest date by which the national standards conflicting with the EN have to be withdrawn(dow) 1999-03-01 These normative annexes list the particular national requirements, as laid down in the relevant laws, regulations and standards, which specify the protective distances for each of the CENELEC member countries at the time when this standard was prepared. They may be different to the protective distances given in EN 50186-1. The national annexes are summarized by the relevant member countries.
