CREPITUS Probatio Level explosionis Probatur Fans

1. Apparatus electrica diversus indicatur secundum gradus securitatis ad usum in atmosphaerae explosivae gas, quae dividuntur in zonis: Zone 0, Zone 1, et Zone 2.

2. Classificatio gas vel vapor explosive mixturis cadit in tria genera: IIA, IIB, et IIC. Haec divisio imprimis fundatur in Maximum Experimental Tutum Gap (MESG) aut minimum Ignition Current Ratio (MICR).

3. The temperatus junctio accendendi medium specificum in plures regiones divisum est. Haec includit T1: infra CDL° C; T2: 300°C < T ≤ 450°C; T3: 200°C < T ≤ 300°C; T4: 135°C < T ≤ 200°C; T5: 100°C < T ≤ 135°C; T6: 85°C < T ≤ 100°C.
