4.Degree pollution 1
No pollution only dry, non-conductive pollution occuring.
.5 Inhomogeneous field
Electrical field with basically non-constant voltage gradients between the
electrodes (inhomogeneous field).1.1.4 Homogeneous Field
Electrical field with basically constant-voltage gradients between the
electrodes (homogeneous field), such the electrical field between two
spherical bodies whose radii are larger than the distance between them.
4.6.6. has no
influence (air-conditioned clean and dry rooms).
Degree pollution 2
Only non-conductive pollution occurs except that occasionally temporary
conductivity caused condensation expected (sales rooms, fine-
mechanic workshops, laboratories, test labs, medical rooms).
Degree pollution 3
Conductive pollution occurs dry, non-conductive pollution, which
becomes conductive result condensation, which expected
(industrial and agricultural plants, unheated storage rooms, workshops,
boiler rooms).
Degree pollution 4
This pollution generates persistent conductivity, for example, result of
conductive dust, rain snow (outdoor and open-air locations)
