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 Cilacap Refinery, Central Java. For a refinery of this size, outside contractors and turnaround specialists often know the IECEx scheme. A certificate of conformity with a schedule of conditions would be the shared document. For the IS-04Z1 these are targets and not yet issued, so they cannot support a purchase today.
