Pipeline link
Crude oil reaches the refinery by pipeline from a tanker port a few kilometres away, so classified areas are spread between port and refinery sites.
Gothenburg hosts Sweden's largest general energy port, with about 2,200 tanker calls a year and 20.7 million tonnes of energy products handled in 2025, and the Preemraff Göteborg refinery nearby. Gothenburg lies on Sweden's west coast about halfway between Copenhagen and Oslo, with a rocky archipelago offshore and the Kattegat, an arm of the North Sea, beyond. An ATEX and IECEx smartphone distributor in Gothenburg (Göteborg) would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Gothenburg (Göteborg) 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.

| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | Gothenburg (Göteborg): Pumping stations and valve areas, Bulk fuel tank storage, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Göteborg. 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.
Crude oil reaches the refinery by pipeline from a tanker port a few kilometres away, so classified areas are spread between port and refinery sites.
A maritime climate with cool, damp winters on the west coast; outdoor equipment should tolerate rain and low temperatures.
The Port of Gothenburg handles nearly 30 percent of Sweden's foreign trade; crude oil was its main import at about 20 million tonnes in 2013, and 24 scheduled rail shuttles serve Norway and Sweden.
Göteborg Landvetter Airport is 25 km south-east of the centre, and the city has the largest tram network in Scandinavia with over 80 km of double track, though soft ground means there is no metro.
The Port of Gothenburg is the largest harbour in Scandinavia, at the mouth of the Göta älv, Scandinavia's largest drainage basin, and trade and shipping have always played a major role in the city's economy.
Chalmers University of Technology and technical schools linked to SKF and Volvo supply engineering talent, so trained technicians for industrial and marine work are available locally.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Gothenburg (Göteborg). At the Energy Port and the Preemraff refinery, a procurement reviewer would expect certificate numbers and markings for any device entering Zone 1 berths, pump areas or tank storage. Offering both ATEX and IECEx routes suits the mix of Swedish and international tanker and contractor crews calling at the port, though the terminal's own rules decide acceptance.
A distributor for Gothenburg (Göteborg) 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 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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are refinery process units, tanker berths and loading arms, pumping stations and valve areas, bulk fuel tank storage. 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 Gothenburg (Göteborg).
The Port of Gothenburg is Scandinavia's largest harbour, with frequent container and ro-ro services, so imports to Sweden and the region often arrive here. Allow time for customs and conformity checks on electrical and radio equipment, and confirm requirements with your forwarder.
Marine and port activities, fuel and chemical storage on the waterfront, and manufacturing plants for vehicles and components can all include flammable gas, vapour or dust areas. Each operator sets its own zones, so request classification drawings before using handheld devices.
The west coast has a maritime climate with cool, damp winters, so outdoor equipment should tolerate rain and low temperatures. The IS-04Z1 is designed to IP68 for water and dust, and has a 4,000 mAh battery. Cold-weather runtime has not been published, so ask for the datasheet.
