See table 1 for examples of each of these environments [2,3]. Office and laboratory areas are considered pollution degree 2 environments according to safety standards and certification bodies. Any equipment designed for, or placed in a test station environment should have a pollution degree 2 rating in order to meet recognized safety standards.

No pollution or ice dry, nonconductive pollution occurs.

The pollution generates persistent conductivity caused by conductive dust, rain, or snow. The pollution has no effect. Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment. Affect of Pollution degree on safety distances. Temporary conductivity caused by condensation is to be expected. Examples of pollution degree environments.
