9.4 Environmental conditions during operation
Environmental conditions are defined according to DIN EN 60721-3-3 in dif‐
ferent classes. They are based on long-term experiences and take all influ‐
encing variables into account, e.g., air temperature and air humidity.
Overview of allowed classes of ambient conditions according to DIN EN
60721-3-3 during operation
Classification type Allowed class
Classification of climatic environmental conditions 3K22
Classification of biological environmental conditions 3B1
Classification of mechanically active materials 3S6
Classification of mechanical environmental conditions 3M12
Tab. 9-1: Allowed classes of environmental conditions during operation
Based on DIN EN 60721-3-3, some limit values are partially defined in the
following, which our products are allowed to be exposed to during operation.
Observe the detailed description of the classifications to take all of the factors
which are specified in the particular class into account.
Allowed operation conditions
Environmental factor Unit Value
Air temperature °C 0 ... +40
