Hungary: rules and approvals
Under ATEX, Category 3 equipment may be self-certified by the manufacturer with a technical dossier, while Category 1 and 2 usually involve a notified body, which affects what Hungarian buyers should ask for.

Field notes · Hungary
More about Hungary that matters for portable equipment
Hungary: infrastructure
The Arad-Szeged natural gas pipeline connects Romania and Hungary, so border compressor and metering stations belong to the national gas network.
Hungary: industry on the ground
Wanhua-BorsodChem, based at Kazincbarcika in north-east Hungary, produces isocyanates (MDI and TDI), PVC and chlor-alkali products, and is a major chemical employer for plant maintenance and shutdown contractors.
Hungary: background
MOL was established on 1 October 1991 as the legal successor of nine members of the National Oil and Gas Trust, which dated from 1957, giving Hungary a long industrial oil and gas history.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Hungary. Hungarian sites such as Százhalombatta, Tiszaújváros and Kazincbarcika use contractors who also work in other countries. For them the IECEx scheme is a familiar reference, with a certificate of conformity naming the equipment and a schedule of conditions setting conditions of use. IECEx certification for the IS-04Z1 is in progress; none can be cited yet.

Questions · Hungary
Frequently asked questions
Can we buy an IECEx cell phone in Hungary 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 IECEx cell phone in Hungary cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which sites in Hungary does this cover?
The market guide for Hungary covers Százhalombatta, Tiszaújváros, Kazincbarcika, Dorog, 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 documentation language is needed for Hungarian sites?
Hungarian is the working language, and ATEX instructions are typically expected in the language of the destination country. Providing Hungarian instructions with the certificate pack often helps, though international operators may also accept English. Check with the site safety office.
Does Hungary require ATEX for handheld devices in hazardous areas?
Hungary is an EU member, so ATEX Directive 2014/34/EU applies to equipment and Directive 1999/92/EC to workplace zoning. Zone 1 and Zone 2 devices should carry CE and Ex markings with instructions in the local language. Operators usually add their own permit and registration rules.
Is ATEX the evidence a Hungarian operator will ask for?
ATEX is the usual reference in the EU, and Hungary applies it through national law. Some operators or international contractors also ask for IECEx. Ask the operator's HSE or explosion-protection lead which evidence they accept before ordering.
