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. This page explains what to look for in an industrial mobile phone for Borlänge, 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 Borlänge: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| 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.
The companies on site and the hazardous-area types a handset is likely to meet there.

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.
Borlänge Central is a railway junction for routes toward Falun, Mora and Ludvika and links to Gävle and Stockholm, and Dala Airport lies 8 km south-east, with Arlanda 214 km away.
Dalarna University was founded in 1977 as a joint college for Falun and Borlänge, and the town hosts the head office of the Swedish Transport Administration, Trafikverket.
Borlänge has long been an industrial town around the Domnarvet iron and steel works, now SSAB, and the Kvarnsveden paper mill, owned by Stora Enso.
Construction of the Domnarvet ironworks began in 1872, and a railway between Falun and Ludvika via Borlänge opened in 1875, making the town a strategic junction for the works.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Borlänge. Large works in Dalarna run permit-to-work and contractor induction for each site, and a phone used on rounds would normally be enrolled in the operator's or contractor's EMM or MDM. The IS-04Z1 is designed to support EMM/MDM. Charging would be done in safe areas, outside classified zones, between shifts.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
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.
Inland Dalarna can be cold in winter, so batteries and touchscreens may perform less well outdoors. Typically users keep spare batteries warm and check the device's rated temperature range against site conditions, while mills and steelworks may require protective cases.
Mills typically have combustible dust from wood and fibre, flammable gases in energy and chemical recovery areas, and solvent stores. Each site classifies its own areas, so ask the mill's safety team for zone drawings and whether handheld devices are permitted.
Large works here run their own contractor induction and permit-to-work systems, so access to classified areas is arranged through each operator. A phone would normally be listed and approved as part of that process. Ask the operator's HSE or procurement team what device evidence it requires.
