Shenhai Explosion-Proof
Kev faib tawm T4 qhia tias cov khoom siv hluav taws xob yuav tsum ua haujlwm nrog qhov siab tshaj plaws ntawm qhov kub tsis tshaj 135 ° C.. Cov khoom uas muaj qhov ntsuas T6 muaj feem xyuam rau ntau pawg kub, whereas T4 li yog sib xws nrog T4, T3, T2, thiab T1 tej yam kev mob.
| 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 |
The reason T6 is not typically used is that many devices, particularly those requiring high power or consisting of purely resistive circuits, are unable to achieve the stringent low-temperature conditions stipulated by the T6 classification.
