IEC 60079-1 – Flameproof Path Properties

A flameproof joint or flame path is defined by IEC 60079-1 as a “place where the corresponding surfaces of two parts of an enclosure, or the conjunction of enclosures, come together and which prevents the transmission of an internal explosion to the explosive gas atmosphere surrounding the enclosure”.

Overview of Different Flameproof Sealing Methods

Considering the requirements for Flameproof type ‘d’ (Ex d) enclosures and the need for cable glands to maintain the integrity of the protection method by containment, we can observe the different options available to achieve this. Recognition must first be given to the fact that cables must be robust enough to enable a sealing ring to be applied, and ensure safety of installations. See also Clause 9.3.1 of IEC 60079-14:2013.
