Ubufakazi Bokuqhuma Izinga Labalandeli Bobufakazi Bokuqhuma

1. Izimpahla zikagesi ezihlukene zihlukaniswa ngokusekelwe emazingeni okuphepha ukuze zisetshenziswe emimoyeni yegesi eqhumayo, ezihlukaniswe ngezigaba: Indawo 0, Indawo 1, kanye neZone 2.

2. Ukuhlukaniswa kwegesi noma umhwamuko eziqhumayo izingxube ziwela izigaba ezintathu: IIA, IIB, kanye ne-IIC. Lesi sigaba sisekelwe ngokuyinhloko ku-Maximum Experimental Safe Gap (I-MESG) noma I-Minimum Ignition Current Ratio (I-MICR).

3. I izinga lokushisa ukuqoqwa kokushisa okuphakathi okuthile kuhlukaniswe izigaba eziningana. Lokhu kufaka phakathi i-T1: ngaphansi kuka-450°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.
