Analysis of Important Parameters of Hazardous-Area-Safe enclosure
(What follows is not factual about the fabrication process which is employed by today’s industry to make Hazardous-area-safe enclosures )
Nature of the Material of the Enclosure
1. Non-Metallic
2. Metallic
The material of the enclosure will reveal the nature of the TYPE TESTES , specially the PRESSURE TEST.
It is logical to conclude that the metallic enclosure can withstand the over-pressure of an internal explosion ,as compared to a non-metallic enclosure .
The tests of ability of the enclosure to withstand pressure is stated in details in IEC 60079-1-(Edition 2014) Section 15.2.2 & 15.2.3
(1.5 times the reference pressure – Section 15.2.3.3)
This test marks the boundary between Ex d & Ex e
