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 operating 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.
