The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for refinery and cracker rounds on the west coast, mill and recovery boiler areas inland, and winter shifts in the north where a device is handled through two layers of glove. This page explains what to look for in a rugged smartphone for Sweden, 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 Sweden: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. 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 |
| Where it applies | Sweden: Lysekil, Gothenburg river bank, Stenungsund | Classified by the site operator |
An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Sweden. 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 Sweden market guide.
Preem's refineries provide roughly half of all petroleum products consumed in Sweden and nearly 65% of its production is sold abroad, mainly in north-west Europe, so its refineries are large and busy classified-area sites.
The Port of Gothenburg is the largest in the Nordic countries and handles nearly 30% of Sweden's foreign trade, about 39 million tonnes a year, so most imported equipment can enter through one port.
The Lysekil refinery plan began in 1945 when the consumer-owned oil company OK was formed, but the plant was only inaugurated in 1975, and it remains one of the area's main employers.
Transport, especially aviation fuel and cars, is still majority powered by fossil fuels, so fuel depots, airports and filling stations remain the largest flammable-liquid networks outside refineries.
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 Sweden. Sweden asks a handset to work in the cold and through winter clothing, and meltwater follows a device indoors. A rugged build covers low temperature and thermal shock, and IP68 sealing covers snow and meltwater. A northern site will reject a device whose lower limit stops at a Central European winter. IP68 is not explosion protection.
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.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
The market guide for Sweden covers Lysekil, Gothenburg river bank, Stenungsund, Nynäshamn, 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.
Winter temperatures can be well below freezing, particularly in the north, which reduces battery capacity and affects touchscreen use with gloves. Check the lowest rated ambient temperature on the certificate, glove-friendly input and whether charging is possible outside the classified area.
Wood and biomass fuel handling creates combustible dust, so Zone 21 or Zone 22 areas may exist at boiler plants and fuel stores. Check that the device carries a dust marking suitable for the classification, not only a gas marking, and confirm with the plant operator.
Gloved operation is a design consideration, but screen response with gloves, physical key behaviour and one-handed use should be tested on the first day of a trial rather than accepted on paper. Use an evaluation unit on a real winter round.
