Ex-Proof Smartphone in Göteborg
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. Tanker loading, tank storage and refinery units create Zone 1 areas. If you are specifying an Ex-proof smartphone for Gothenburg (Göteborg), this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Gothenburg (Göteborg): geography and layout
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.
Gothenburg (Göteborg): logistics and access
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.
Gothenburg (Göteborg): logistics and access
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.
Gothenburg (Göteborg): people and language
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Gothenburg (Göteborg). A marking check at the Energy Port would compare the device's gas group and temperature class with the products handled, since fuels at the tank farms and refinery units differ. The IS-04Z1 target is II 2 G Ex ib IIC T4, which is in progress and not yet certified. Compare that against each area's drawings.

Specifying an Ex-proof smartphone for Göteborg
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Göteborg
Frequently asked questions
Can we buy an Ex-proof smartphone in Göteborg today?
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.
What does an Ex-proof smartphone in Göteborg cost?
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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Gothenburg (Göteborg) would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Is Gothenburg a good base for work across western Sweden?
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.
Does the Gothenburg climate affect handheld equipment?
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.
What entry checks apply to contractors at Gothenburg's Energy Port?
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.
