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.

Questions · Cilacap Refinery
Frequently asked questions
Can we buy an IECEx mobile phone in Cilacap Refinery today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an IECEx mobile phone in Cilacap Refinery cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Cilacap Refinery, Central Java would use it?
Likely candidates are refinery process units, crude and product tank farms, marine loading facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
What products at Cilacap create the main gas hazards?
The complex processes crude into gasoline, diesel, kerosene, aviation fuel and LPG, plus asphalt and petrochemicals. Flammable vapour from light products and pressurised LPG are the usual concerns, but the plant defines its zones, so ask for the current classification.
Why does the number of assets at Cilacap matter for safe equipment choice?
With more than 85,000 maintainable assets and an ongoing safety-critical-element review, the refinery is formalising what is classified and how it is maintained. That usually means device approvals and area classification records are checked closely, so bring documentation.
How wet does Cilacap get, and does it matter for a handset?
The climate is hot and humid with a heavy rainy season, so devices on tank farms and jetties meet rain often. Check sealing and charging arrangements. Rain protection is separate from explosion protection, so confirm the permitted device list with the operator.
