IEC

IEC

Short for International Electrotechnical Commission. This is the all-important, internationally recognized authority that maintains International Standards related to electronics.

Countries around the world participate in the arduous task of creating unified standards for a very wide range of industries, including those for Explosive Atmospheres.

Although the standards are unified, interpretation may vary from market to market. Local Ex authorities make their own interpretations, which can lead to confusion for both manufacturers and buyers of Ex equipment. In such cases, organizations – manufacturers, notified bodies, etc. – may make recommendations to change IEC standards to help eliminate conflicting interpretations.
