I-Class A ihlanganisa amagesi afana ne-ethane, i-methanol, i-ethanol, kanye nophethiloli; Ikilasi B liqukethe amagesi afana negesi yokuhlala, i-ethylene, kanye ne-ethylene oxide.
The T3 temperature classification applies to environments up to 200℃ and includes 36 common gases such as gasoline and butyraldehyde. The T4 classification limits temperatures to 135℃, also for 36 gases including acetaldehyde and tetrafluoroethylene.
