In order to be certified as explosion or flame proof, the enclosure must be strong enough not to fracture or distort under the internal pressures generated in order to contain explosions and prevent propagation. When testing a product for Explosion proof protection, it will have to undergo several actual explosions within simulated environments.
The chart below gives an overview of North American and International Explosion and Flame Proof protection standards:
