Hazardous Area Certification - Saudi Aramco

[charz]

The Saudi Aramco specification says,

8.3.1 IEC or Ex labeled equipment/component meeting requirement of IEC 60079 and certified by one of the agencies in the approved IECEx certification bodies (ExCBs) under IECEx Certified Equipment Scheme is acceptable. Method of protection must be marked and correspond with NEC Article 505 requirements for suitable protection method(s) for the hazardous area where the equipment is applied.

Are they implying that the equipment manufactured according to IEC shall have marking as per NEC; because from my experience, most of the IEC based equipment do not have Class/Zone marking or AEx marking.

Any comments?

As a counter-point, the IEC world devices I've worked with had IEX/EEX/ATEX/Class-Zone markings and had accompanying listing papers. Looks to me the spec is trying to sync up w/ NEC requirements for Class/Zone identification for hazardous areas.
