Common IECEx Standards

The IECEx certification system is based on a series of internationally recognized standards that define the safety requirements for equipment intended for use in explosive atmospheres. These standards ensure consistent assessment of both electrical and non-electrical equipment used in hazardous areas.

IECEx certification commonly involves the following key standards:

IEC 60079-0 — General Requirements

IEC 60079-1 — Flameproof Enclosures “d”

IEC 60079-7 — Increased Safety “e”

IEC 60079-11 — Intrinsic Safety “i”

IEC 60079-18 — Encapsulation “m”

IEC 60079-31 — Protection by Enclosure for Dust Ignition “t”

ISO 80079-36 — Non-electrical Equipment for Explosive Atmospheres

ISO 80079-37 — Non-electrical Equipment Protection Concepts

These standards form the technical foundation of IECEx certification and are widely used to evaluate equipment safety, performance, and compliance in potentially explosive atmospheres. Depending on the equipment type and protection concept, additional related standards may also apply.
