Creepage & Clearance distances in many IEC/EN standards including IEC61010-1
and thereby EN61010-1 are drawn from IEC60664-1: Insulation coordination for
equipment within low-voltage systems - Part 1: Principles, requirements and
tests.

Subject:        DERIVATION OF CREEPAGE AND CLEARANCES


All
Does anyone know from where the values for creepage and clearances given in
EN61010-1 ("safety requirements for electrical equipment for measurement,
control and laboratory use - part 1 general requirements") are derived i.e.
are there other standards "below" 61010 in this respect?
Thanks

Ian Gordon
