Intrinsic Safety (“i”) is a type of explosion-proof safety design that inherently limits the energy of potential sparks and thermal effects generated by equipment under normal operation or any fault condition to a level incapable of ignition, elimina...

I. Area Classification for Explosive and Flammable Gas Atmospheres Zone 0: Areas where explosive and flammable gas mixtures continuously, frequently appear for long durations or persist for extended periods under normal conditions, e.g., certain part...

Ga, Gb and Gc are protection classes applied to equipment for use in explosive gas atmospheres, and they constitute an indispensable part of explosion-proof equipment markings. ※ Ga: Equipment for use in explosive gas atmospheres with a "very high" p...

Which is safer for equipment: Flameproof (Ex d) protection or Intrinsic Safety (Ex i) protection? And how to choose between them? STS briefly explains the relationship and differences between Flameproof and Intrinsic Safety protection from the follow...

A flameproof enclosure is capable of withstanding an internal explosion of flammable mixtures that penetrate into the enclosure through any joint surface or structural gap of the enclosure without being damaged, and it will not ignite the external ex...

ATEX certification is a mandatory certification for explosion-proof products issued by the European Union. It is an explosion-proof directive within the framework of CE certification, with the directive code 2014/34/EU. The certification standard is ...
