Remote sites
Large operations such as Grasberg, at about 4,100 metres elevation, rely on long supply chains by air, road and sea.
Indonesian mining includes coal in Kalimantan, nickel in Sulawesi and the Grasberg copper-gold complex in Papua. Fuel storage, coal handling, process plants and smelters create hazardous areas, with dust areas at coal preparation and underground work at Grasberg. If you are specifying an ATEX and IECEx smartphone for Indonesian mining regions, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Indonesian mining regions: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Indonesia Mining. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Large operations such as Grasberg, at about 4,100 metres elevation, rely on long supply chains by air, road and sea.
The Indonesia Morowali Industrial Park, begun in 2013 in Central Sulawesi, is reported to be the largest nickel-based industrial area, with 11 smelters.
PT Borneo Alumina Indonesia finished an alumina refinery in West Kalimantan with a capacity of 1 million tonnes a year, starting operations in December 2024, and Freeport built a 0.6 million tonne copper smelter at Manyar in East Java.
Nickel output reached about 2.2 million tonnes in 2023 and relies heavily on coal-fired power, accounting for around 22 percent of national energy and industrial emissions, so captive coal power plants sit beside many smelters.
The Indonesia Morowali Industrial Park in Central Sulawesi, the country's largest nickel processing site, covers 2,000 hectares and is served by its own seaport, an airport and a 2 GW coal power plant.
In 2024 Indonesia was estimated to be the world's leading producer of mined nickel at 62 percent of global output, and second for tin at 19 percent and cobalt at 12 percent.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Indonesian mining regions. Mine safety officers across Kalimantan, Sulawesi and Papua would expect certificate evidence that matches the marking, with a schedule of conditions. The IS-04Z1 evidence is in progress. A dual ATEX and IECEx route helps operators such as Freeport, Kaltim Prima and Vale, whose contractors are drawn from several countries.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are coal handling and preparation plants (dust, zone 21), fuel and lubricant storage, underground mine areas, smelter and process plant areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Typical examples are underground methane or coal-dust zones, fuel storage and workshops, explosives magazines, smelter and processing areas with gases or dust, and captive power plants. Each operator classifies its own site, so confirm the zones with the mine's safety department.
Yes. Smelters and acid-leach plants emphasise process gases, chemicals and high temperatures, while coal mines emphasise methane and combustible dust. The device choice and the area type differ, so ask each site for its classification and permit rules.
Remote operations rely on long supply chains, so a failed device may take time to replace. Plan spares, local service access and offline-capable apps. Check heat, wet and altitude conditions at each site. Confirm site rules with the operator.
