Category Standard or description
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.
Pollution Degree 3 Conductive pollution, or dry, nonconductive pollution that becomes
conductive due to condensation. These are sheltered locations where
neither temperature nor humidity is controlled. The area is protected from
direct sunshine, rain, or direct wind.
Pollution Degree 4 Pollution that generates persistent conductivity through conductive dust,
rain, or snow. Typical outdoor locations.
