According to IEC 62368, there are various degrees of pollution.
Pollution degree 1
This pollution degree is dry and non-conductive. These include moisture and dust that enter through the sealed packages of subassemblies, components, and equipment.
Pollution degree 2
Here, non-conductive pollution happens unless there is condensation. Often, it is common in general laboratories and office environments.
Pollution degree 3
This type involves conductive pollution. Otherwise, an expected condensation induces non-conductive pollution. It happens among factory equipment. |
