ATEX and IECEx Mobile Phone in Kalimantan Mining
Kalimantan hosts some of Indonesia's largest open-pit coal mines, including Kaltim Prima Coal at Sangatta in East Kalimantan and Adaro's Tutupan mine in South Kalimantan. Hazardous-area work centres on fuel storage, coal handling and preparation, and mine power plants. This page explains what to look for in an ATEX and IECEx mobile phone for Kalimantan coal mining region, and where the IS-04Z1 stands against that list today.

Kalimantan coal mining region: industry on the ground
Coal bed methane reserves of about 12.8 trillion cubic metres lie mainly in Kalimantan and Sumatra, which is a reminder that methane can accompany coal seams, though development has been limited.
Kalimantan coal mining region: geography and layout
Indonesia's significant coal deposits are in South Sumatra, East Kalimantan and South Kalimantan, and reserves are estimated to last over 80 years at current rates of extraction.
Kalimantan coal mining region: industry on the ground
Indonesia's coal production reached a record 836 million tonnes in 2024, up from 775 million tonnes in 2023, and the country is the world's largest coal exporter.
Kalimantan coal mining region: climate and equipment wear
East Kalimantan has a dry season from May to October and a rainy season from November to April; average humidity in 2013 was between 83 and 87 percent, with temperatures ranging from about 22 to 36 degrees Celsius.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
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 Kalimantan coal mining region. Mine reviewers at Sangatta or Tutupan would expect certificate evidence matched to the marking, with its schedule of conditions. The IS-04Z1 evidence is in progress. A dual ATEX and IECEx route helps the operators and the mining contractors whose fleets and workforces are large.

Specifying an ATEX and IECEx mobile phone for Kalimantan Mining
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval

Questions · Kalimantan Mining
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Kalimantan Mining 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 ATEX and IECEx mobile phone in Kalimantan 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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Kalimantan coal mining region would use it?
Likely candidates are coal handling and preparation plants (dust, zone 21), fuel and lubricant storage, mine-site power generation, coal loading terminals. 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 are the main hazardous-area concerns at a Kalimantan coal mine?
Combustible coal dust around crushers, conveyors, stockpiles and loading, plus fuel storage and workshops. Open-pit sites typically have fewer gas risks than underground mines, but the operator defines its zones, so ask for them before using handheld devices.
How should I plan equipment supply for remote Kalimantan sites?
Most deliveries go by sea to Balikpapan, Samarinda or Banjarmasin and then by road or barge, so allow longer lead times. Stock spare batteries and chargers and confirm customs and radio type-approval requirements with your freight agent.
What practical issues come with large contractor-heavy fleets at Kalimantan mines?
Many crews share devices and sites, so enrolment, ownership and return procedures matter. Heat, humidity and dust affect battery and seals. Charge only in safe areas. Check the operator's approved-vendor list before purchase. Confirm the current process with the site operator.
