Bill,

Most standards, including IEC 60664-3, only recognize conformal coating for
pollution control.  Pollution Degree 1, by itself often buys you a smaller
spacing. 

In to use a coating as insulation control and still smaller spacings, you
need to use a qualified encapsulant.

Subject: Insulation enhancement?



Premise: EN61010-1:2001
On a PCB, where adjacent surface traces do not provide double insulation
between haz-live and accessible circuits, is the spot application of
conformal coating to the traces acceptable as supplementary insulation?
