Romania: projects and investment
OMV Petrom completed an offshore campaign in the Lebăda Est and Lebăda Vest fields on the Histria block in the Black Sea in 2010, showing that offshore work is an established part of Romanian upstream activity.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for Romanian refineries, well sites, gas plants and port terminals rather than for an office. If you are specifying an Ex-proof mobile phone for Romania, 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 Romania: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Romania: Ploiești and Brazi, Năvodari, Constanța | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Romania. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Romania market guide.
OMV Petrom completed an offshore campaign in the Lebăda Est and Lebăda Vest fields on the Histria block in the Black Sea in 2010, showing that offshore work is an established part of Romanian upstream activity.
Petrom was privatised in late 2004 and sold to the Austrian company OMV, the largest privatisation deal in Romania's history at the time, and has been named OMV Petrom since 2010.
Gas production is around 25 million cubic metres a day, with about 100 billion cubic metres of onshore reserves and an estimated 40 billion offshore, so both Carpathian-area fields and Black Sea sites matter.
Two reactors at Cernavodă generate about 18-20% of Romanian electricity, and the country also has substantial coal deposits and considerable hydroelectric capacity, so mines, dams and power plants all feature.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Romania. A marking check in Romania would start with the target II 2 G Ex ib IIC T4 and the zone it is compared against. IIC covers hydrogen-bearing streams at refineries and chemical platforms, while the fertiliser complex at Târgu Mureș adds dust, so Zone 21 evidence is read alongside the gas marking.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
The market guide for Romania covers Ploiești and Brazi, Năvodari, Constanța, Vadu and Corbu, among others. Site-level pages are linked below.
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.
Continental winters can bring sub-zero temperatures, which cut battery capacity and can make touchscreens harder to use with gloves. Check the lowest rated ambient temperature on the certificate and plan spare batteries and warm storage for outdoor work at pipeline stations and refineries.
Refineries, gas fields and compressor stations, Black Sea offshore fields, chemical works and power plants are the main examples. Five refineries remained by 2018 with spare capacity for export. Confirm site lists with each operator and ask for its zone drawings.
It is designed with four-constellation GNSS, 4G LTE and Wi-Fi so a lone worker at a well site or compressor station can be located and stay connected. Real coverage depends on the mobile network at the site, so test it on your own field route during an evaluation.
