EN 'A' always calls up EN 'B' rather than IEC 'B', if EN 'B' exists. There is a trap for the unwary here; the ENs are listed in Annex ZA of the EN that is doing the referring, and you don't see Annex ZA unless you buy the EN. The references are sometimes NOT identical, or even technically equivalent, to the IEC Normative References in clause 2 of the IEC standard (some standards don't conform to the rule that they should be in clause 2). For example, EN 'B' may have a different date >from the latest IEC 'B', and/or it may include Common Modifications and/or Special National Conditions and/or A Deviations, that are not in IEC 'B'. -- Regards, John Woodgate, OOO - Own Opinions Only.
