Ndi Mulingo Uti wa Kuphulika-Umboni Wapamwamba, CT1 kapena CT4

Gulu la CT4-proof-proof classification limadziwika kuti ndilokwera kwambiri.

Kalasi Ndi Level	Ignition Kutentha Ndi Gulu
-	T1	T2	T3	T4	T5	T6
-	T＞450	450≥T＞300	300≥T＞200	200≥T＞135	135≥T＞100	100≥T＞85
Ine	Methane
IIA	Etani, Propane, Acetone, Phenethyl, Ine, Aminobenzene, Toluene, Benzene, Ammonia, Mpweya wa Monoxide, Ethyl Acetate, Acetic Acid	Butane, Ethanol, Propylene, Butanol, Acetic Acid, Koma Ester, Amyl Acetate Acetic Anhydride	Pentane, Hexane, Heptane, Decane, Octane, Mafuta, Hydrogen sulfide, Cyclohexane, Mafuta, Palafini, Dizilo, Mafuta	Etere, Acetaldehyde, Trimethylamine		Ethyl nitrite
IIB	Propylene, Acetylene, Cyclopropane, Coke Oven Gasi	Epoxy Z-Alkane, Epoxy Propane, Butadiene, Ethylene	Dimethyl Ether, Isoprene, Hydrogen sulfide	Diethylether, Dibutyl Ether
IIC	Gasi wa Madzi, haidrojeni	Acetylene			Carbon Disulfide	Ethyl nitrate

Zonse zimaganiziridwa, chipangizo chilichonse chimakhala ndi mlingo wa IIC, kusonyeza kufanana pa metric iyi; komabe, zosiyana zimapezeka m'magulu awo a kutentha: Zida za T6 zimakhala ndi kutentha kwapamwamba kwambiri kwa 85 ° C, Zipangizo za T4 zimafika pa 135 ° C, ndi zida za T1 zimatha kufikira 450°C.

Zipangizo zotsimikizira kuphulika kwa T4 ndizolemekezeka kwambiri ndipo zimatha kulowa m'malo mwa zida za T1.. Kwenikweni, kusintha zida za CT1 ndi CT4 pakugwiritsa ntchito kulikonse kumatsimikizira chitetezo.
