What is the explosion-proof grade?
Ex(ia) II C T6 means:
Logo content:
- Symbol: Ex(ia) II C T6
- Meaning: This marking indicates that the equipment is designed to be safe in explosive environments.
Explosion-proof statement:
- Ex: The "Ex" prefix stands for "explosion-proof" and indicates that the device meets international or national safety standards, such as China’s GB standard or European ATEX regulations.
Explosion-proof mode:
- ia: This refers to the intrinsic safety (IS) design, which ensures that the device cannot produce a spark or heat sufficient to ignite an explosive atmosphere under normal or fault conditions. It is suitable for installation in **Zone 0**, where explosive gases are present continuously or for long periods.
Gas category:
- II: This denotes that the device is intended for use with **non-mining** explosive gases (as opposed to Zone 1 or 2 for mining applications).
- C: This specifies the gas group, indicating that the equipment is suitable for **Class II C** gases, which include highly flammable substances like hydrogen and ethylene.
Temperature group:
- T6: This means that the surface temperature of the device will not exceed **85°C**, even under maximum load conditions. This is crucial for preventing ignition of volatile gases in hazardous areas.
The full marking "Ex(ia) II C T6" provides a clear indication of the equipment's suitability for use in potentially explosive environments. It ensures compliance with strict safety protocols and helps prevent accidents in industries such as chemical processing, oil and gas, and manufacturing.
