H IEC 61010--031:2002. Particular requirements for handheld probe assemblies
for electrical measurement and test equipment.
Test and measuring equipment.
A measure of the contaminates that could occur in the environment around and
within a product. Typically the internal environment inside a product is
considered to be the same as the external. Products should be used only in the
environment for which they are rated.
H Pollution Degree 1. No pollution or only dry, nonconductive pollution
occurs. Products in this category are generally encapsulated, hermetically
sealed, or located in clean rooms.
H Pollution Degree 2. Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by condensation must
be expected. This location is a typical office/home environment. Temporary
condensation occurs only when the product is out of service.
H Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution
that becomes conductive due to condensation. These are sheltered locations
where neither temperature nor humidity is controlled. The area is protected
from direct sunshine, rain, or direct wind.
H Pollution Degree 4. Pollution that generates persistent conductivity through
conductive dust, rain, or snow. Typical outdoor locations.
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.
Terminals on this product may have different installation (overvoltage) category
designations. The installation categories are:
H Measurement Category IV. For measurements performed at the source of
low-voltage installation.
H Measurement Category III. For measurements performed in the building
installation.
H Measurement Category II. For measurements performed on circuits directly
connected to the low-voltage installation.
H Measurement Category I. For measurements performed on circuits not
directly connected to MAINS.
Overvoltage Category II (as defined in IEC 61010-1)
