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 meets specific explosion-proof standards and is suitable for use in hazardous environments.
Explosion-proof statement:
- Ex: Indicates that the device complies with international or national explosion-proof standards, such as China’s GB or Europe’s ATEX regulations.
Explosion-proof mode:
- ia: Stands for "Intrinsically Safe" at level ia, which means the device is designed to prevent ignition of explosive gases even under normal or fault conditions. It can be safely used in **Zone 0**, where explosive gas mixtures are likely to occur continuously.
Gas category:
- II: Refers to equipment intended for use in non-mining environments (as opposed to Zone I, which is for mining applications).
- C: Indicates that the device is suitable for use with **Class II C** flammable gases, such as hydrogen or ethylene.
Temperature group:
- T6: Specifies that the maximum surface temperature of the device does not exceed **85°C**, ensuring it will not ignite flammable gases in its environment.
This rating ensures that the equipment is safe and reliable in potentially explosive atmospheres, making it ideal for industrial and chemical environments.
