Port access
The Energy Port runs ISPS security level 1 with gate controls, including random alcohol testing at Gate 1, so visitors and contractors pass formal entry checks.
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. Tanker loading, tank storage and refinery units create Zone 1 areas. If you are specifying an ATEX and IECEx mobile phone for Gothenburg (Göteborg), this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Gothenburg (Göteborg): 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| 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): Refinery process units, Tanker berths and loading arms, Pumping stations and valve areas | 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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The Energy Port runs ISPS security level 1 with gate controls, including random alcohol testing at Gate 1, so visitors and contractors pass formal entry checks.
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.
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.
Gothenburg has an oceanic climate moderated by the Gulf Stream, with summer highs of 20 to 22 degrees Celsius, windy winters between about minus 1 and 4 degrees, and moderate rain through the year.
The Götaverken shipbuilding company was founded in 1841 and stayed in business until 1989, which left a legacy of marine engineering skills and waterfront industrial land.
Major companies operating plants in the area include SKF, Volvo cars and trucks, and Ericsson, and Volvo Cars is the largest single employer in Gothenburg, not counting supplier jobs.
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 short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
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.
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.
Yes. The city sits on the west coast with an international airport, a large port and regional rail and road links, and a deep technical workforce from local industry and universities. Plan travel to individual sites separately and confirm each site's induction rules.
The climate is mild for its latitude, but winters are cold and windy and rain is regular, with salt air near the harbour. Typically users want good ingress protection, battery performance in cold weather and routine cleaning of exposed connectors.
The Energy Port runs ISPS security level 1 with gate controls, including random alcohol testing at Gate 1, so visitors and contractors pass formal entry checks. Device approval is separate and set by the operator. Ask the port or refinery HSE team what evidence they expect for a phone.
