G.1 Introduction
The term "insulation co-ordination" explains the process for co-ordinating the constituents of an
electrical insulation, i.e. solid/liquid insulation, clearances and creepage distances.
NOTE The dimensioning of insulation thicknesses performed by solid insulation and insulation distances performed by liquid insulation
materials is not covered by this standard.
However, the use of this standard for the determination of clearances and creepages needs some
additional explanations: The values of the tables of Annex A are based on EN 60664-1 and
