Isho ukuthini I-Explosion-Proof Level AT1

Ayikho imikhiqizo yenkampani njengamanje enesitifiketi sokuvikela ukuqhuma se-Exd IIA T1(Iqembu lokushisa elilele).

III	C	T135℃	Db	IP65
III Uthuli olungaphezulu		T1 450℃	Ma	IP65
		T2 300℃	Mb
		T3 200℃
	A Izihlahla ezindizayo ezivuthayo		Futhi
		T4 135℃
			Db
	B Non conductive dust	T2 100℃	UDkt
	C Uthuli lwe-conductive	T6 85℃

Isigaba se-IIA sisho ukuvikelwa kokuqhuma kwegesi ku-Class IIA, ikakhulukazi propane, isetshenziswa kakhulu kuma-fuel dispensers;

Isigaba sokushisa se-T1 sicacisa ukuthi izinga lokushisa eliphezulu lempahla angeke lidlule ku-450°C.
