Climate
Humid continental climate with cold winters (January averages about -1 degrees C), so outdoor rounds in winter call for cold-tolerant batteries and gloved operation.
Borlänge is the largest urban centre in Dalarna, central Sweden, and is built around the SSAB Domnarvet strip-steel works and the Stora Enso Kvarnsveden paper mill. Steel and paper processing involve fuel gas, chemicals and fine dust, so Zone 1 and Zone 21 classification can apply in plant areas. An IECEx smartphone distributor in Borlänge would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Borlänge 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |
| Where it applies | Borlänge: Fuel and process gas systems, Chemical and oil storage, Dust-generating process areas (Zone 21) | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Borlänge. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Humid continental climate with cold winters (January averages about -1 degrees C), so outdoor rounds in winter call for cold-tolerant batteries and gloved operation.
SSAB's Borlänge site employs around 1,800 people and is being developed as a processing and distribution hub as SSAB moves to new production processes.
The town lies on the Dalälven river downstream of the confluence of the Österdalälven and Västerdalälven, and it is the largest urban centre in the province of Dalarna, with about 44,900 residents in 2020.
SSAB describes its Borlänge works, established in 1878, as its largest strip rolling system, making hot-rolled and cold-rolled high-strength steel for automotive, heavy-duty transport, lifting and container uses, with around 1,700 employees.
The four blast furnaces and two Kaldo converters at Domnarvet were shut down in 1981, and the site since then has developed around its hot strip rolling mill.
SSAB's industrial area lies in downtown Borlänge, the Dal river flows through the site, and the works contain around 30 km of railroad track.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Borlänge. Borlänge's two large works are served by outside maintenance and project contractors, some working across several countries. An IECEx certificate of conformity, read with its schedule of conditions, gives such visitors a common reference. For the IS-04Z1 that certificate is still in progress, so nothing can be presented to a Dalarna works yet.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Borlänge. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are fuel and process gas systems, chemical and oil storage, dust-generating process areas (zone 21). Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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 Borlänge.
Dala Airport is 8 km south-east with limited services, and Stockholm Arlanda is 214 km away, so many visitors arrive by train or road. Plan equipment delivery by road freight and confirm gate procedures with the site.
Steel works typically involve process gases, fuel gas and oxygen systems, hydraulic oil, coating lines, and dust from coal, ore or scale. The operator defines gas and dust zones, so ask SSAB for its classification drawings and portable-device rules before bringing equipment.
Winters in Borlänge are cold, with January averaging around -1 degrees C, so cold-tolerant batteries and gloved operation matter for outdoor rounds. The IS-04Z1 has a 4,000 mAh battery, but cold performance has not been published for it. Ask for the datasheet before specifying winter use.
