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 Balikpapan, East Kalimantan. The RDMP upgrade brings contractors used to the IECEx scheme into a Pertamina site. A certificate of conformity and its schedule of conditions would be the shared reference. For the IS-04Z1 those documents are targets, not issued, so they cannot yet support any purchase.

Which areas at Balikpapan, East Kalimantan would use it?
Likely candidates are refinery process units, residual fluid catalytic cracking unit, crude and product storage, marine crude mooring and tanks. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Balikpapan, East Kalimantan?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Balikpapan, East Kalimantan.
Which operator should I contact for equipment approval at the Balikpapan refinery?
Refinery Unit V is run by PT Kilang Pertamina Balikpapan, part of the Pertamina group. Contractors and suppliers normally register through Pertamina's vendor processes and follow the site's own permit and induction rules, so confirm the current route with the plant.
Are there new and old process areas at Balikpapan to consider for classification?
Yes. The upgrade added a residue catalytic cracking unit and raised capacity by 100 thousand barrels a day beside the existing units, so area classification drawings can differ between revamped and legacy sections. Ask for the current hazardous-area drawings for the unit you will work in.
Will the RDMP upgrade change what handsets are accepted at Balikpapan?
Possibly, because new units bring new classified areas and contractor equipment rules. The operator sets the requirements for each phase. Ask Pertamina or its contractors for current device approval procedures and do not assume earlier approvals cover new areas. Confirm with the site operator.
