Shenhai e fakamoʻoni fakaʻauha
ʻOku feʻunga ʻa e IIB ʻo e kalasi mo e ngaahi ʻatakai ʻoku hoko ai ʻa e mixtures ʻo e ngaahi kasa mo e ʻea.
| Kulupu kasa/kulupu mafana | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, Maʻuʻanga Fakamatala, methyl ester, acetylene, kasa, ongo ʻo e leʻo, ʻesiti ʻakeliliki, benzene, styrene, kaponi kaponi, ethyl acetate, acetic ʻesiti, chlorobenzene, methyl acetate, Maʻuʻanga Fakamatala | Methanol, ethanol, ethylbenzene, fakaʻofoʻofa, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, ethanol, heptane, octane, cyclohexanol, turpentine, naphtha, lolo fokotuʻu (kau ai ʻa e penisini), lolo penisini, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ʻEta | Butadiene, epoxy kasa, ethylene | Dimethyl ʻEta, acrolein, fakapaaki ʻo e carbide | |||

ʻOku vahevahe ʻa e fakafaʻahinga ʻo e fakamoʻoni ki he ngaahi tuʻunga ʻo e Palaimeli ki he keli mo e tuʻunga maʻolunga ki he ngaahi fale. ʻI he tuʻunga hono ua, ʻOku kau ʻi he fakafaʻahinga iiki ʻa e IIA, IIB, mo e IIC, ʻi he fakahokohoko ʻo e ngaahi meʻa ʻe malava ke fakamoʻoniʻi ʻaki e fakaʻauha: IIA < IIB < IIC. The 'T' category denotes mafana ʻo e ʻea ngaahi kulupú. A ‘T’ rating implies that the equipment maintains a surface temperature below 135°C, with T6 being the optimal safety level, advocating for as low a surface temperature as possible.
Ko hono aofangatuku, this explosion-proof product is designed as an intrinsically malu electrical device, intended for use with Class B gases where the surface temperature does not exceed 135°C.
