5. Pollution degree
IEC 61010-1 specifies different types of pollution environments, for which different protective 1 specifies different types of pollution environments, for which different protective
measures are necessary to ensure safety. Harsher environments require more protection, and the measures are necessary to ensure safety. Harsher environments require more protection, and the
protection against the pollution which is to be found in a certain environment depends mainly on
the insulation and the enclosure properties. The pollution degree rating of the DVM indicates in the insulation and the enclosure properties. The pollution degree rating of the DVM indicates in
which environment the device may be used.
Pollution degree 1 No pollution or only dry, nonconductive pollution occurs. The pollution has no
influence (only to be found in hermetically sealed enclosures) influence (only to be found in hermetically sealed enclosures).
Pollution degree 2 Only nonconductive pollution occurs. Occasionally, temporary conductivity Only nonconductive pollution occurs. Occasionally, temporary conductivity
caused by condensation is to be expected (home and office
under this category).
Pollution degree 3 Conductive pollution occurs, or dry nonconductive pollution occurs that Conductive pollution occurs, or dry nonconductive pollution occurs that
becomes conductive due to condensation that is to be expected
