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:

7.14.3.6 Use of the transponder in the hazardous area for dusts
The equipment is suitable for dusts whose ignition temperatures for a dust layer of 5 mm are
higher than 210 °C (smoldering temperature). The ignition temperature specified here
according to IEC 60079-0:2011 for ignition protection type ib in this case references the
smoldering temperature of a layer of combustible flyings (ib IIIA) or alternatively non-
conductive dusts (ib IIIB).
