Hungary: infrastructure
Four operating reactors built between 1982 and 1987 form the Paks Nuclear Power Plant, and nuclear is the main domestic energy source, with almost half of Hungary's energy imported as of 2024.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for Hungarian refinery units, polymer plants, pharmaceutical solvent areas and gas installations. This page sets out how an explosion proof mobile phone supply route to Hungary will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An explosion proof mobile phone for Hungary cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Hungary. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Hungary market guide.
Four operating reactors built between 1982 and 1987 form the Paks Nuclear Power Plant, and nuclear is the main domestic energy source, with almost half of Hungary's energy imported as of 2024.
MOL is active in exploration and production, refining, distribution, petrochemicals, power generation, trading and retail, with operations in over 30 countries and 2,400 service stations in ten countries as of 2025.
MOL's Danube Refinery at Százhalombatta started up in 1965 and has a capacity of about 8.1 million tonnes a year, making it one of the largest refineries in Central and Eastern Europe.
The Matra power plant, the last coal electricity producer, supplied about 9% of Hungary's electricity in 2020 and was served by coal mines in Visonta and Bükkábrány, with a gas combined-cycle replacement planned.
“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 Hungary. In Hungary explosion-proof is a common phrase, but refinery units, polymer plants and pharmaceutical solvent suites use different protection concepts. Flameproof Ex d suits some fixed equipment, while a handset moving between rooms is better served by intrinsic safety. The IS-04Z1 is designed around intrinsic safety for that reason.
Supply of the IS-04Z1 to Hungary starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
The market guide for Hungary covers Százhalombatta, Tiszaújváros, Kazincbarcika, Dorog, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Continental winters can bring sub-zero temperatures, which reduce battery capacity. Check the lowest rated ambient temperature on the certificate and whether touch input works with gloves. Plan spare batteries and warm storage for outdoor work at refineries and pipeline stations.
MOL is the largest integrated oil, gas and petrochemical group, and the Paks plant and gas network operators also have hazardous areas. Each company runs its own supplier approval, so contact its procurement and HSE teams for current device and contractor requirements.
Gas groups, dust and temperature needs differ between a refinery and a solvent suite. A device would need a marking that suits each classification. Check each plant's zone documents, since the answer depends on the operator's classification rather than the device alone.
