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.

Ex-Proof Cell Phone in Romania
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. This page explains what to look for in an Ex-proof cell phone for Romania, and where the IS-04Z1 stands against that list today.

WhereRomania
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Romania
More about Romania that matters for portable equipment
Romania: who works there
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.
Romania: geography and layout
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.
Romania: infrastructure
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“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.

Specifying an Ex-proof cell phone for Romania
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 · Romania
Frequently asked questions
Can we buy an Ex-proof cell phone in Romania today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof cell phone in Romania 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 Ex marking will the IS-04Z1 carry?
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.
Which sites in Romania does this cover?
The market guide for Romania covers Ploiești and Brazi, Năvodari, Constanța, Vadu and Corbu, 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.
How do Romanian winters affect Ex handheld devices?
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.
Where is hazardous-area work concentrated in Romania?
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.
Can the IS-04Z1 keep a position fix at an isolated Romanian well site?
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.
