Izay manana ambaratonga avo indrindra tsy mipoaka

Fanasokajiana tsy misy fipoahana: Ny lanjany ambony indrindra an'ny IIC, mandrakotra ny fampiharana ny IIB sy IIA; IIB dia mihoatra ny IIA amin'ny laharana.

Maximum ambonin'ny mari-pana: Izany dia manondro ny mari-pana ambony indrindra azon'ny fitaovana elektrônika ao anatin'ny fepetra fiasana voatondro ratsy indrindra, mety handrehitra ny atmosfera mipoaka manodidina. The maximum surface temperature must be lower than the flammable temperature.

Ohatra: In environments where explosion-proof sensors are used, if the ignition temperature of the baomba gases is 100°C, then the maximum surface temperature of any component of the sensor must remain below 100°C.
