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 sets out how an intrinsically safe mobile phone supply route to Sweden will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An intrinsically safe mobile phone for Sweden cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Sweden. Intrinsic safety suits winter rounds across long distances, between a mill, a terminal and a steelworks, where the handset is operated in gloves, often in the dark. A handheld that limits ignition energy allows photographs and readings in the zone. Gloved operation and one-handed use are worth testing on day one.
Nothing can be bought for Sweden today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you at launch.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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 circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
The market guide for Sweden covers Lysekil, Gothenburg river bank, Stenungsund, Nynäshamn, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
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.
