Ndeupi Une Yepamusoro Kuputika-Uchapupu Level, BT4 kana CT4

Iyo inoputika-inoratidza kupatsanurwa kwemidziyo yeCT4 inodarika iyo yeBT4 michina.

Kirasi Uye Level	Ignition Temperature Uye Boka
-	T1	T2	T3	T4	T5	T6
-	T＞450	450≥T＞300	300≥T＞200	200≥T＞135	135≥T＞100	100≥T＞85
I	Methane
IIA	Ethane, Propane, Acetone, Phenethyl, Ene, Aminobenzene, Toluene, Benzene, Ammonia, Carbon Monoxide, Ethyl Acetate, Acetic Acid	Butane, Ethanol, Propylene, Butanol, Acetic Acid, Butyl Ester, Amyl Acetate Acetic Anhydride	Pentane, Hexane, Heptane, Decane, Octane, peturu, Hydrogen sulfide, Cyclohexane, peturu, Parafini, Diesel, Petroleum	Ether, 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 remvura, Hydrogen	Acetylene			Carbon Disulfide	Ethyl nitrate

BT4 inorongedzerwa seKirasi B tembiricha boka, uko iyo yakanyanya tembiricha yepamusoro yeT4-yakayerwa zvishandiso haipfuure 135 ° C. CT4 inobata Class C kuputika-proof rating, kuenzaniswa neBT4, uye inokodzera nharaunda dzine magasi ane ngozi akadai sehydrogen neacetylene, kuchengetedza tembiricha yepamusoro ye135°C.

Kuwanda Kwekushandisa

BT4 inokodzera magasi akajairika kusanganisira methane, ethane, peturu, uye hydrogen sulfide.

CT4 inobatanidza huwandu hwakawanda hwezvishoma zvinoputika magasi, senge hydrogen uye gasi remvura padanho reCT1, acetylene pa CT2 level, uye kabhoni disulfide padanho reCT4.
