If potentially explosive mixtures outside
atmospheric conditions are possible in the
container, the cleaning process is not part of
the intended use under these conditions
and requires a separate hazard assessment.

Table 2.5-3: Explanation of EX marking – dust
The maximum surface temperature of the device is determined by the ambient temperature in the
system to be cleaned
(container) and the temperature of the cleaning medium.
The permissible temperatures must be taken into account (see
