apparatus in which in normal operation a mixture of gases or vapours capable of being ignited does
not normally occur or with a high probability does so only seldom and briefly.
The following instructions absolutely must be observed when using these devices.
•
Because of the identical construction in principle of the devices of category 2 certified by IBExU
(notified body), these studies relating to the internal space are used for illustration purposes.
This certification relates to the following device types:
The certification is a type test per Directive 2014/34/EU. It relates to all the devices of the
manufacturer “Gardner Denver Thomas GmbH” with the designation “EX II 3G IIC T3X.”
In the specific case these are devices with the following type designations:
