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.
