Temperature class assignment for gases and a radiated power of 10 mW to 2000 mW ERP
If the radiated power of an antenna radiating into the hazardous area or of an antenna
located in the hazardous area in the 865 - 868 MHz frequency band cannot exceed the
radiated power selected in the following diagram, the maximum permitted ambient
temperature range can be found in the corresponding temperature function of the diagram.
This makes the following temperature class assignment valid:
