If there is a standard IEC 69999 and a standard DIN IEC 69999, then they are identical. But if there is a standard DIN EN 69999, then somewhat pedantically, they are NEVER identical. The EN always includes an Annex ZA, which 'translates' the IEC normative references into EN/HD references. But the differences may be MUCH larger, including Common Modifications (that apply to all EU and EFT countries), and A-deviations and Special National Conditions, that apply only to some countries. > >I wonder if I should be cautious about the potential difference >between, say BSI/EN 60204-1 and DIN/EN 60204-1?

They are intended to be, and SHOULD be, identical. But translation and printing errors do occur. An EN is approved by receiving not more than 25% of the votes cast being negative votes, and there is also a weighted voting process. But once approved, ALL member states and EFTA members have to publish the standard (intended to be identical, but see above) as a national standard (DIN EN 69999, BS EN 69999, ES EN 69999 etc.) -- OOO - Own Opinions Only.
