Field notes · Indonesia
More about Indonesia that matters for portable equipment
Indonesia: infrastructure
Pertamina operates six oil refineries with a combined capacity of around 1 million barrels a day, as of 2013, and has not built a new refinery since Balongan opened in West Java in the mid-1990s.
Indonesia: rules and approvals
Radio and telecom equipment certification by SDPPI is compulsory in Indonesia, with a three-year validity, local testing and a local representative required, and a marking requirement.
Indonesia: rules and approvals
Technical requirements for 5G devices follow Perdirgen No. 5/2021, so 5G-capable phones are tested against that rule as part of SDPPI certification.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Indonesia. From Cilacap to Bontang and Teluk Bintuni, rounds and inspections are spread across islands where a replacement device may be a flight away. An intrinsically safe handheld lets crews record and report at the point of work. That is the design intent, pending certification and local approval.

Specifying an intrinsically safe cell phone for Indonesia
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 · Indonesia
Frequently asked questions
Can we buy an intrinsically safe cell phone in Indonesia 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 intrinsically safe cell phone in Indonesia 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 does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which sites in Indonesia does this cover?
The market guide for Indonesia covers Cilacap, Central Java, Balikpapan, East Kalimantan, Dumai, Riau, Balongan, West Java, among others. Site-level pages are linked below.
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 conditions should devices handle at Indonesian industrial sites?
Tropical sites typically combine heat, high humidity, heavy rain and, near the coast, salt air, so check ingress protection, corrosion resistance and operating temperature range. Confirm site-specific requirements with the operator, including any area classification and approved-device lists.
How does Indonesia's island geography affect equipment logistics?
With thousands of islands, many sites are reached by sea or air, and delays are common. Plan extra lead time and spares for devices, chargers and batteries, and ask the operator or contractor about shipping, customs and site approval rules for each island location.
How would a remote island site get support?
Supply after certification would be through authorised distributors, and none has been appointed yet. For remote sites, ask about spares, replacement time and training before purchase, and agree the logistics route with the operator. Trial units can be tested to check connectivity and battery use first.
