Intrinsic safety certification is actually a type of explosion-proof certification. Specifically:

Intrinsic Safety Certification

This certification indicates that the equipment adopts the intrinsic safety (i) type of explosion-proof protection. Intrinsic safety explosion protection is achieved by limiting the energy of the equipment, such as restricting the operating voltage, current, capacitance, inductance, etc. This ensures that even if sparks are generated inside the equipment's circuit, they are not strong enough to ignite the surrounding explosive atmosphere. This type of certification is suitable for low-power products, handheld devices, and the like.

Explosion-Proof Certification

This is a broader category that encompasses multiple explosion-proof protection modes, including flameproof (d), increased safety (e), pressurized enclosure (p), powder filling (m), and others. All these modes are designed to ensure that the equipment will not cause or trigger an explosion when used in explosive atmospheres.
