Atex / IECEx Wiring Methods

[killer76]

Wanted to fine the best location to find Current wiring methods, for Atex / IECEx installations
Haven't been in electrical design for some time and want to see what may have changed.

I am ok with off shore installs, and want to see if anyone can provide information for onshore installation.
API RP-14 & API RP-14Z is what I have used

I recall conduit seals were not typically permitted

Thank you

Neither ATEX nor IEC Ex are recognized in US domestic installations. NEC Articles 505 & 506 are the closest. API RP-505 and NFPA 497 & 499 are the appropriate classification Standards.

Be careful US “Zone” equipment is marked AEx rather than just Ex to meet US domestic Standards.
