See table 1 for examples of each of these environments [2,3]. To be found in industrial environment or construction sites harsh environments. The pollution has no effect. Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs.

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. Examples of pollution degree environments Clearly, ATE environments i. The pollution generates persistent conductivity caused by conductive dust, ifc, or snow.

Pollution Degree Rating for Electrical Equipment

Pollution degree 3 is a harsher environment typical in many industrial manufacturing areas. Office and laboratory areas are considered pollution degree 2 environments according to safety standards and certification bodies. See table 1 for examples of each of these environments [2,3]. 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. No pollution or only dry, nonconductive pollution occurs.
