Affect of Pollution degree on safety distances. See table 1 for examples of each of these environments [2,3]. Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs.

The pollution has no effect. This classification is important since it affects creepage and clearance distances required to insure the safety of a product. Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment.

No pollution or only dry, nonconductive pollution occurs. Examples of pollution degree environments. The pollution has no effect. Normally only nonconductive pollution occurs. No pollution or only dry, nonconductive pollution occurs.

Temporary conductivity caused by condensation is to be expected. Affect of Pollution degree on safety distances. Pollution degree 3 is a harsher environment typical in many industrial manufacturing areas. The pollution generates persistent conductivity caused by conductive dust, rain, or snow.
