5. Pollution degree

IEC 61010-

1 specifies different types of pollution environments, for which different protective

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

which environment the device may be used.

Pollution degree 1

No pollution or only dry, nonconductive pollutio

n occurs. The pollution has no

influence (only to be found in hermetically sealed enclosures)

Pollution degree 2

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

becomes conductive due to cond

ensation that is to be expected

Pollution degree 4

The pollution generates persistent conductivity caused by conductive dust or by

rain or snow. (exposed outdoor environments and environments where high

humidity levels or high concentrations

of fine particles occur)

certain restrictions in use apply that are related to pollution which can occur within the

environment of use. Refer to the table above.
