The port facilities include a coal-fired power station that is to be replaced by 2027 with a 265 megawatt liquefied natural gas combined cycle plant, which will add an LNG supply chain to the site. Concentrate goes by 166-kilometre slurry pipeline to the port at Amamapare, so hazardous areas include fuel, power, process plant and underground workings. If you are specifying an IECEx mobile phone for Timika and the Grasberg mining district, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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 Timika and the Grasberg mining district. Grasberg's scale draws international contractors and suppliers who recognise IECEx. A certificate of conformity with a schedule of conditions would be reviewed alongside PT Freeport Indonesia's own rules. For the IS-04Z1 these are targets, not issued, so no specification should rely on them yet.

Questions · Timika Mining
Frequently asked questions
Can we buy an IECEx mobile phone in Timika Mining today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an IECEx mobile phone in Timika Mining 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 Timika and the Grasberg mining district would use it?
Likely candidates are concentrator and process plant, fuel storage and distribution, concentrate port and dewatering, underground mine areas. 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.
Do underground mines at Grasberg use block caving and what does that mean for equipment?
Grasberg has block-cave and other underground operations with large ore flows and ventilation. Equipment in underground areas typically needs the approvals the operator specifies, and the mine controls access, so ask for its underground device and communications requirements.
Does the move to LNG power affect hazardous-area planning in Timika?
A planned 265 MW LNG-fired plant by 2027 would add natural gas storage and handling near the port, which sites usually classify as hazardous areas. Check with the operator for updated classification drawings if you will work near new power facilities.
Are underground areas at Grasberg covered by the same rules as surface plant?
Not necessarily. Underground mines have their own classification and approval rules set by the operator. A device accepted at the concentrator may not be accepted underground. Ask the operator's central safety team about each area.
