Exd IIC T4 na Exd IIC T5 babagi ratings ledakan-bukti sarupa, kalayan hiji-hijina bédana nyaéta suhu maksimum anu tiasa dicapai nalika operasi.
| Grup suhu pakakas listrik | suhu permukaan maksimum allowable pakakas listrik (℃) | Suhu ignition gas / uap (℃) | tingkat suhu alat lumaku |
|---|---|---|---|
| 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 | T6 |
Suhu permukaan maksimum anu diidinan béda-béda: pikeun Exd IIC T4, éta 135 darajat Celsius, sedengkeun pikeun Exd IIC T5, it is capped at 100 darajat Celsius.
Given that lower operating temperatures enhance safety, the explosion-proof classification CT5 is considered superior to CT4.
