Pollution Degree A measure of the contaminates that could occur in the

environment around and within a product. Typically the internal

environment inside a product is considered to be the same as the

external. Products should be used only in the environment for

which they are rated.

Pollution Degree 1

No pollution or only dry, nonconductive pollution occurs.

Products in this category are generally encapsulated,

hermetically sealed, or located in clean rooms.

Pollution Degree 2

Normally only dry, nonconductive pollution occurs.

Occasionally a temporary conductivity that is caused by

condensation must be expected. This location is a typical

office/home environment. Temporary condensation occurs

only when the product is out of service.
