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 an explosion proof mobile 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. An operator's own vendor approval is a separate step. 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 main operators, industrial areas and sites that the SAMS Belgium market guide covers.
Chemicals, pharmaceuticals, petroleum products, metals and motor vehicle assembly feature among Belgium's industrial base, and chemicals are also a leading export, which means many process plants with flammable solvents and gases.
Fluxys is the main natural gas transmission operator, and gas imports came mainly from the Netherlands and Norway in 2021, so compressor and metering stations are part of the classified-area network.
Dutch-speaking Flanders and French-speaking Wallonia have different industrial histories and languages, and Belgium has a multilingual, well-trained workforce, so Dutch and French documents are often requested.
Industry is concentrated in Flanders in the north, around Brussels, and along the Sillon industriel through Liège and Charleroi, so hazardous-area work is split between a coastal north and an older steel and chemicals south.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Belgium. Explosion proof is the everyday phrase, but the Antwerp cluster mixes steam crackers, refineries and polymer plants, so the real protection concept matters. Flameproof Ex d suits fixed equipment; the IS-04Z1 is designed around intrinsic safety so a handheld can cross solvent and powder areas. The operator classifies each area, not SAMS.
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.
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 intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
Belgium is an EU member, so ATEX Directive 2014/34/EU applies to equipment placed on its market, and employers zone workplaces under Directive 1999/92/EC. Zone 1 and Zone 2 devices should carry the Ex and CE markings. Confirm the exact accepted categories with each site operator.
Dutch in Flanders, French in Wallonia and sometimes English at international chemical sites. Instructions are typically expected in the user's language for ATEX equipment, so ask the operator which language it expects. Bilingual documentation packs can avoid delays at gate control.
Camera control is why ordinary phones are refused at the gate on Seveso sites. Android 16 with EMM and MDM lets the camera, location services and application list be set centrally, so permissions can be shown during evaluation. Whether a site accepts it still depends on its own rules. Confirm with the operator before taking a unit in.
