The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Houston and the Houston Ship Channel. The channel hosts large operators and visiting contractors who work to different national regimes. The IECEx route is intended to give them a common reference: a certificate of conformity and its schedule of conditions, which the operator would read for limits of use. SAMS has not yet been issued either document for the IS-04Z1, which remains pre-launch.
