Shenhai Splużjoni-Prova
Explosion-proof rating:
Explosion-proof equipment with a CT4 rating is classified as Exd IIC T4. BT4 explosion-proof equipment is rated as Exd IIB T4, which is a lower explosion-proof rating than CT4 equipment.
| Kategorija ta' Kundizzjoni | Klassifikazzjoni tal-Gass | Gassijiet rappreżentattivi | Enerġija Minima ta' Spark ta' Tqabbid |
|---|---|---|---|
| Taħt Il-Minjiera | I | Metanu | 0.280mJ |
| Fabbriki Barra Il-Minjiera | IIA | Propan | 0.180mJ |
| IIB | Etilene | 0.060mJ | |
| IIC | Idroġenu | 0.019mJ |
Applicability:
CT has the widest range of applicability.
Gas environment:
CT is an explosion-proof rating for acetylene and idroġenu livelli. If there are gases like acetylene or hydrogen in the environment, CT-rated explosion-proof equipment is required. BT-rated equipment is not suitable for acetylene environments and is only considered a moderate livell kontra l-isplużjoni.
