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. If you are specifying a rugged cell phone for Belgium, 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 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |

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.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Belgium. A device on a jetty at Zeebrugge or the Scheldelaan lives with driven rain, salt air and cleaning rather than fine dust. IP68 sealing and a rugged build are aimed at that duty cycle, including wash-down. IP68 is an ingress rating, and explosion protection comes from the ATEX certificate and marking, not from the enclosure rating.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.

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.
