The new series, 63044, are based on the corresponding IEC standards, as you can see by the leading '6'. The older series, 50491, are home-grown (in Europe) CENELEC standards, as you can see by the leading '5'.

Hi John,

Do you have an idea why a new series of standards are being introduced rather than updating the older ones?

Thanks

James

These delays in updating the OJ list are very troublesome. Lawyers are involved, which says it all. The 63044 series (and other new, not yet listed standards) cannot be formally used to demonstrate conformity. A possible solution is to ensure that the product passes the OJ listed standard, cite it on the DoC and explain in addition in a Note to the DoC that the new standard is also met. Of course, it might not be possible to satisfy both standards, if they have 'absolutely conflicting' requirements (what is explicitly mandatory in one is explicitly prohibited in the other) but that is probably a rare case.
