Ang BT4 giklasipikar isip usa ka grupo sa temperatura sa Class B, diin ang pinakataas nga temperatura sa ibabaw sa T4-rated nga mga himan dili molapas sa 135°C. Ang CT4 adunay usa ka Class C explosion-proof rating, itandi sa BT4, and is suitable for environments with hazardous gases such as hydrogen and acetylene, maintaining a maximum surface temperature of 135°C.
Scope of Use
BT4 is suitable for common gases including methane, ethane, petrolyo, ug hydrogen sulfide.
CT4 encompasses a broader range of less common eksplosibo mga gas, such as hydrogen and water gas at the CT1 level, acetylene at the CT2 level, and carbon disulfide at the CT4 level.
