There is no IEC definition of 'pollution degree', but from the IEV (free access on the IEC web site): 442-01-28 pollution any addition of foreign matter, solid, liquid or gaseous that can produce a permanent reduction of dielectric strength or surface resistivity of the insulation NOTE – Ionized gases of a temporary nature are not considered as to be a pollution. -- John Woodgate - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
