Hi all, I have been asked a question regarding the following:
"use in a Zone 1 and Zone 2 classified area. This equipment shall be certified EEX d and EEx n by a relevant authority (e.g. BASEEFA, CENELEC etc.) and shall be suitable for Gas Group IIB and Temperature Class T3." Can anyone elaborate on the above information? What standard defines "Zone 1" or "Zone 2"? What standard defines "EEX d" and "EEX n"? What about "Gas Group IIB" and "Temperature Class T3?" Any clarification, elaboration, elucidation and/or explanation that the group members could provide would certainly be appreciated.
