The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Timika and the Grasberg mining district. A marking check would first confirm whether an area is gas or dust, then compare zone, gas group and temperature class. Fuel storage is gas. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, is unapproved and does not cover underground rules the operator may apply.

Questions · Timika Mining
Frequently asked questions
Can we buy an Ex-proof mobile phone in Timika Mining today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof mobile phone in Timika Mining cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
How do I become a SAMS distributor for Timika and the Grasberg mining district?
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 Timika and the Grasberg mining district.
What makes the Timika and Grasberg site different for handheld devices?
Altitude, heavy rain, long underground haulage and remote supply make it demanding. Underground mines can have gas or dust, and surface plants have flotation chemicals, so confirm area classification with the operator and plan for battery life and spares.
How is equipment normally delivered to Timika?
The operation uses its own port at Amamapare, an airstrip and long access roads built for the mine, and Timika is the regional town. Expect long lead times, customs clearance in Indonesia and site security and induction procedures before devices go underground.
How does altitude and rain at Grasberg affect a handset?
Grasberg sits at about 4,100 metres and the region is very wet, so temperature, condensation and battery behaviour matter. Check the rated operating range and sealing. IP68 is not explosion protection. Confirm site requirements with the operator.
