Explosion-proof mobile power box implementation standards

What are the international standards for explosion protection of electrical & non-electrical equipment?

Internationally, the standpoints on the explosion protection of electrical and non-electrical equip-ment are co-ordinated by specialized IEC and ISO working groups. In the area of electrical engineering, internationally harmonized design agreements were formulated in IEC standards at a very early stage.

Which applications require explosion proof equipment?

There are many applications which require explo-sion proof equipment. During the over 100 years of electrical explosion protection, principles and techniques have been developed which allow the use of electrical measuring technology, even where, for example in reaction vessels, an explosive atmos-phere is permanently present.

Why is explosion proof equipment important?

Explosion proof equipment is able to exclude one of the preconditions for an explosion - the ignition source - and is in that way an important contribution to explosion protection. In domestic areas, architec-tural measures ensure that normally an explosive atmosphere cannot be formed.

What is explosion protection?

A type of protection in which the parts which could ignite an explosive atmosphere are located inside an enclosure which can withstand the pressure of an explosion of the explosive mixture inside, and prevents the transmission of the explosion to the explosive atmosphere surrounding the enclosure.

Can a non-explosion proof electrical enclosure be used in a hazardous area?

Using Non-Explosion Proof standard electrical enclosures in a hazardous area is comparable to a hand grenade.

What is secondary explosion protection?

Such solution, by providing type(s) of protec-tion is referred to as secondary explosion protection. These days, the construction of explosion proof equipment goes far beyond the field of electrical engineering. As will be demonstrated in the further descriptions, non-electrical equipment will also require testing or at least assessment.
