Belgium: infrastructure
Nuclear power typically supplies 50-60% of domestic electricity, and in 2023 the lives of Doel 4 and Tihange 3 were extended to 2035, so long-running plant maintenance continues alongside the gas network.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, aimed at the chemical belt along the Scheldt, the terminals at Zeebrugge and the platforms in Hainaut. This page explains what to look for in an IECEx smartphone for Belgium, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Belgium: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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 Belgium. 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 Belgium market guide.
Nuclear power typically supplies 50-60% of domestic electricity, and in 2023 the lives of Doel 4 and Tihange 3 were extended to 2035, so long-running plant maintenance continues alongside the gas network.
Belgium imports raw materials and semi-finished goods and re-exports them after processing, with the Port of Antwerp the most notable of its ports, canals, railways and highways.
After Groningen gas supply fell, Belgium converted affected customers from low-calorific L-gas to high-calorific H-gas, a programme that began in 2018 and was completed by the end of summer 2024.
Under ATEX, equipment in use before July 2003 can remain in use indefinitely provided a risk assessment shows it is safe, which matters when mixing older and newer devices at long-established plants.
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 Belgium. Belgium adds no national scheme behind ATEX, so IECEx matters where a group applies one global specification across plants at Antwerp, Zeebrugge and elsewhere. A reviewer reads the certificate of conformity and the schedule of conditions next to the ATEX file. The two together reduce re-assessment when equipment crosses borders. Both are in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
The market guide for Belgium covers Antwerp right bank, Antwerp left bank, Zeebrugge, Ghent canal zone, 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.
ATEX allows equipment in use before July 2003 to remain in service if a risk assessment shows it is safe. New purchases need to meet the current Directive. Keep the operator's risk assessment on file and ask whether it has additional internal rules for handheld devices.
The Antwerp port area and Flanders are the best-known concentration, with further industry along the Sillon industriel through Liège and Charleroi. Details of individual plants and zones are held by each operator, so request their layout drawings when planning.
Belgian rules expect information that reaches a worker to be in the language of the region where the work happens: Dutch in Flanders, French in Wallonia, and both in Brussels. The manual, safe-use instructions and declaration of conformity are planned in Dutch and French. Certification is still in progress. Check the wording with your site safety adviser.
