E Nang le Boemo bo Phahameng ka ho Fetisisa ba Bopaki ba ho phatloha

Phapang ea bopaki ba ho phatloha: Boemo ba IIC ke bo phahameng ka ho fetisisa, e kenyeletsang likopo tsa IIB le IIA; IIB e feta IIA maemong.

Boholo ba mocheso holim'a metsi: Sena se bolela mocheso o phahameng ka ho fetisisa oo lisebelisoa tsa motlakase li ka o finyellang tlas'a maemo a mpe ka ho fetisisa a boletsoeng, e ka hotetsang seqhomane se potileng. The maximum surface temperature must be lower than the flammable temperature.

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