Although there were some minor objections in the national forward of the 2008 version of BS EN 62353 these have now been resolved as indicated in the national forward of the 2014 version:
This British Standard is the UK implementation of EN 62353:2014. It is identical to IEC 62353:2014. It supersedes BS EN 62353:2008, which will be withdrawn on 9 October 2017.
The UK committee voted against the first edition of this standard, however, the issues raised previously have now been resolved in this edition.
It is not only advisable to use this standard for testing, as it is the only official standard, but can save lots of time, especially if the Alternative leakage current test methods are used.
