OTHER STANDARDS IN USE

Despite the adoption of the MS IEC 60364

67

code of choice and practice This is reflected in the specifications and

certification methods in industry bid documents

Manufacturers are more open towards ISO/IECstandards Especially those geared towards export

Other wiring codes have also been used (though-

built) projects by foreign multinationals The oil and gas industry in particular lean towards

American Codes for Explosion proof standards ANSI: American National Standards Institute NEMA: National Electrical Manufacturers Association
