Uas explosion-Proof theem yog yooj yim dua, T4 los yog T6

T6 yog qib siab uas muaj qib siab.

Kub IEC/EN/GB 3836	Qhov kub tshaj plaws ntawm cov khoom T [°C]	Lgnition kub ntawm combustible tej yam khoom [°C]
T1	450	T>450
T2	300	450≥T>300
T3	200	300≥T>200
T4	135	200≥T>135
T5	100	135≥T>100
T6	85	100≥T>8

'T’ stands rau qhov kub ntsuam xyuas, reflecting qhov kub tseem ceeb heev rau roj explosions nyob rau hauv ib cheeb tsam. piv txwv li, Yog hais tias tus tawg kub ntawm ib flammable roj yog 150°C, Ces tawg-pov thawj khoom uas ntsuam xyuas ntawm T4, T5, los yog T6 yuav tsum tau xaiv.

Muaj ntau yam txias txwv tsis pub tshaj 85°C, T6 yog qhov zoo tshaj plaws thiab kev ruaj ntseg thiab yuav pab tau raws li ib daim tuaj hloov rau lwm yam khoom.
