PER IEC1010 Pollution degree
POLLUTION
Addition of foreign matter, solid, liquid or gaseous (ionized
gases), that may produce a reduction of dielectric strength or
surface resistivity.
POLLUTION degree
For the purpose of evaluating spacing of this product, the
following degrees of POLLUTION in the microenvironment
are defined.
POLLUTION DEGREE 1
No POLLUTION or only dry, non-conductive POLLUTION
occurs. The POLLUTION has no influence.
POLLUTION DEGREE 2
Normal POLLUTION only non-conductive POLLUTION
occurs. Occasionally, however, a temporary conductivity
caused by condensation must be expected.
POLLUTION DEGREE 3
Conductive POLLUTION occurs, or dry, non-conductive
POLLUTION occurs which becomes conductive due to
condensation, which is expected.
NOTE :
In such conditions equipment is
normally
protected
against exposure to direct sunlight, precipitation, and
full wind pressure,
but neither temperature nor
humidity is controlled.
