Temperature class assignment for dusts 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 assignment for dusts and a radiated power less than 1280 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 1280 mW, the temperature class assignment is as follows:
Ambient temperature range
Ambient temperature range for dust and radiated power of 2000 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 2000 mW, the temperature class assignment is as follows:
Ambient temperature range
Temperature class assignment for dusts and a radiated power of 10 mW ERP to 2000 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 can be between the
values 10 mW ERP and 1280 mW ERP, the temperature class assignment is as follows:
