Raws li lub teb chaws tus qauv rau kev tiv thaiv hluav taws xob tawg, BT4 thiab BT6 poob hauv Class IIB.
Kub pawg ntawm cov khoom siv hluav taws xob | Qhov siab tshaj plaws qhov kub thiab txias ntawm cov khoom siv hluav taws xob (℃) | Gas / vapor ignition kub (℃) | Qhov ntsuas kub ntawm cov cuab yeej siv tau |
---|---|---|---|
T1 | 450 | 450 | T1 ~ T6 |
T2 | 300 | > 300 | T2 ~ T6 |
T3 | 200 | 200 | T3 ~ T6 |
T4 | 135 | 135 | T4 ~ T6 |
T5 | 100 | > 100 | T5 ~ T6 |
T6 | 85 | 85; ib | T6 |
Txawm li cas los, lub 'T’ Kev faib tawm muaj feem rau qhov ntsuas kub ntawm cov khoom siv hluav taws xob tawg. Cov khoom siv cais raws li T6 yuav tsum tswj qhov kub thiab txias tsis siab tshaj 85 ° C, T5 yuav tsum tsis pub tshaj 100 ° C, thiab T4 yuav tsum tsis txhob tshaj 135 ° C.
Qhov qis dua ntawm cov khoom siv qhov siab tshaj plaws kub, qhov tsawg dua nws yog ignite atmospheric gases, li no txhim kho kev nyab xeeb. Yog li ntawd, Qhov ntsuas tawg-pov thawj ntawm BT6 tshaj li ntawm BT4.
