Remark
1. IEC (International Electrotechnical Commission) : The international civilian organization which
produces standards for electrical and electronics industry.
2. Pollution degree : It indicates a standard of operation ambient pollution level. The pollution
degree 2 means the condition in which normally, only non-conductive pollution occurs.
Occasionally, however, a temporary conductivity caused by condensation shall be expected.
