Temperature class assignment for gases and a radiated power less than 500 mW ERP
If the radiated power of an antenna radiating into the hazardous area or located in the
hazardous area and operating in the 865 - 868 MHz frequency band cannot exceed the
value 500 mW, the temperature class assignment is as follows:
Ambient temperature range
Temperature class
-25 °C ... +220 °C
T2
-25 °C ... +173 °C
T3
-25 °C ... +108 °C
T4
-25 °C ... +73 °C
T5
-25 °C ... +58 °C
T6
Temperature class assignment for gases and radiated power for 1000 mW ERP
If the radiated power of an antenna radiating into the hazardous area or located in the
hazardous area and operating in the 865 - 868 MHz frequency band cannot exceed the
value 1000 mW, the temperature class assignment is as follows:
