Pertamina: geography and layout
The company is headquartered in Jakarta, while its major refineries and LNG plants are in West Java, East Kalimantan, Central Sulawesi and Aceh, so travel between sites often involves flights.

Explosion-Proof Smartphone for Pertamina
Pertamina is Indonesia's state-owned energy company, headquartered in Jakarta and founded in 1968. Like other contractors, Pertamina holds a cooperation contract with the Oil and Gas Regulatory Body, and it falls under the coordination of the Ministry of State-Owned Enterprises. This page explains what to look for in an explosion proof smartphone for Pertamina, and where the IS-04Z1 stands against that list today.

WherePertamina
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Pertamina: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Supplier approval · Pertamina
How suppliers reach Pertamina
Pertamina lists a general procurement programme and an e-procurement system (GEPSMART) on its website; confirm current vendor requirements with Pertamina. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

More about Pertamina that matters for portable equipment
Pertamina: industry on the ground
PT Badak LNG operates a plant at Bontang in East Kalimantan with 8 trains and a total capacity of 22.5 million tonnes a year, in which Pertamina has invested through an operating company.
Pertamina: industry on the ground
As of 2013 Pertamina operated six oil refineries with a combined capacity of around one million barrels a day, and it has not built a new refinery since Balongan in West Java opened in the mid-1990s.
Pertamina: who works there
In October 2020 Pertamina unveiled a new corporate identity, presenting itself as moving from a national oil and gas company to a global energy company with a stated net-zero ambition for 2060.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Pertamina. Around Indonesian refineries explosion-proof is shorthand, but the concepts behind it differ. Flameproof Ex d suits motors, lighting and junction boxes in process units, whereas a handheld phone relies on intrinsic safety, which limits electrical energy. For rounds at Plaju or Balongan the question is therefore which concept protects a portable device, and the IS-04Z1 uses intrinsic safety.

Specifying an explosion proof smartphone for Pertamina
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
- Separate from the certificate and handled with the site operator.
Questions · Pertamina
Frequently asked questions
Can Pertamina buy the IS-04Z1 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 explosion proof smartphone for Pertamina 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
How does Pertamina approve suppliers?
Pertamina lists a general procurement programme and an e-procurement system (GEPSMART) on its website; confirm current vendor requirements with Pertamina.
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 language should training and documents be in?
Bahasa Indonesia is the national working language, so safety instructions and training for hazardous-area equipment are normally expected in Indonesian, with English often accepted for engineering review. Confirm the language required with Pertamina's procurement and HSE teams.
Which Pertamina facilities are likely to need intrinsically safe handhelds?
Likely places include refineries such as Balongan, LNG plants like Bontang and Donggi Senoro, fuel terminals and tanker jetties. Zone 1 and Zone 2 areas exist around process units, loading and storage. Classification is site-specific, so ask each facility's HSE team for area drawings.
Is humidity a problem for batteries and screens in Indonesian refineries?
Heat and humidity are routine, and IP68 sealing protects the housing from moisture and rain. Battery life still falls in high temperatures, so test the 4,000 mAh battery under local conditions. IP68 is not an explosion rating. Ask the site HSE team how portable devices are charged and stored.
