Category Standards or description
Pollution Degree Descriptions 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 of
fi ce/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.
