Neither through the IEC nor through the German standardisation agencies (DIN, DKE, VDA, etc) is it
possible for two versions of a standard to be in force at the same time. There comes with a standard
version a Publication Date, and on this date the new version comes into force and the old version is
retracted. This is automatic.

I would think yes, because that is how publication dates function at the IEC and in Germany, but I
don't know the Spanish rules.
