IEC 664-1 PDF

Answer. IEC has established four degrees of pollution severity: Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution . “Insulation coordination for electrical equipment in low-voltage systems”.

Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation idc. To be found in industrial environment or construction sites harsh environments. Learn more about our privacy policy. Any equipment designed for, or placed in a test station environment should have a pollution degree 2 rating in order to meet recognized safety standards.

Pollution degree 3 is a harsher environment typical in many industrial manufacturing areas. The pollution has no effect. Pollution degree 3 is a harsher environment typical in many industrial manufacturing areas. Office and laboratory areas are considered pollution degree 2 environments according to safety standards and certification bodies.

The pollution has no effect. This classification is important since it affects creepage and clearance distances required to insure the safety of a product. The pollution generates persistent conductivity caused by conductive dust, rain, or snow. Temporary conductivity caused by condensation is to be expected.

Examples of pollution degree environments Clearly, ATE environments i. Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs.

To be found in industrial environment or construction sites harsh environments. Learn more about our privacy policy. Normally only nonconductive pollution occurs. This classification is important since it affects creepage and clearance distances required to insure the safety of a product.

Affect of Pollution degree on safety distances. Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment. See table 1 for examples of each of these environments [2,3]. Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment. No pollution or only dry, nonconductive pollution occurs. The pollution generates persistent conductivity caused by conductive dust, rain, or snow.

Office and laboratory areas are considered pollution degree 2 environments according to safety standards and certification bodies.
