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. Sweden had the EU's highest share of renewable energy for heating and cooling at 69% in 2022, so biomass boilers and district heating plants with combustible dust are common. Distribution partners for Sweden are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Sweden has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.

| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |

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.
Operators and classified areas drawn from 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.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Sweden. A Swedish marking check reads II 2 G Ex ib IIC T4 for the refinery and cracker areas, with the hydrogen projects at the steelmakers in mind. In the mill sector, wood dust is a primary hazard, so Zone 21 evidence is read as closely as the gas marking, and the lower limit of the ambient range is checked.
A distributor for Sweden would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.

Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Sweden.
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.
