Degree A measure of the contaminates that could
occur in the environment around and within a
product. Products should be used only in the
environment for which they are rated.

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:

occurs. Occasionally a temporary conductivity
that is caused by condensation must be
expected. This location is a typical
office/home environment. Temporary
