It is identical to IEC 61000-4-5:

2、2014. It supersedes BS EN 61000-4-5:2006, which will be withdrawn on 19 June 2017.BSI, as a member of CENELEC, is obliged to publish EN 61000-4-5:2014 as a British Standard. However, attention is drawn to the fact that during the development of this revision, the UK committee voted against its appro

3、val as a European Standard. The concern is that the revision does not adequately consider the situation of low-impedance unshielded unsymmetrical interconnection lines, such as 4-20mA loops. It requires differential transients to be applied, but it is unlikely that these lines will experience differ

4、ential transients in actual installations. Transients will be common mode in nature. The UK committee is considering either an amendment to this standard or to the relevant product standards.The UK participation in its preparation was entrusted by Technical Committee GEL/210, EMC - Policy committee,
