Tab. 5
The classification of gases and vapors in groups with regard to
their explosion group and temperature class applies both to the
medium transferred and to the pump environment.
The pump may only be used to transfer gases and vapors which
belong to the explosion groups II A and II B and the temperature
class T4 (and below) (marked range in Tab. 5) or which are not
explosive.
The pump may only be operated in an environment which contains
an atmosphere belongs to the explosion groups II A and II B and
the temperature class T4 (or below) (marked range in Tab. 5) or
which is not explosive.
