Port logistics
Sjursoya handles container, ro-ro, dry bulk and petroleum cargo.
More than a quarter of the city's population, counting children of immigrant parents, has an immigrant background, so workforces and visiting teams in Oslo are often multilingual. Sjursoya, a peninsula used entirely by the Port of Oslo, is the main oil port for Eastern Norway and handles petroleum products and methanol, which gives Oslo its main classified areas. If you are specifying an Ex-proof mobile phone for Oslo, 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 Oslo: 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 |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Oslo: Petroleum product storage and loading, Methanol and bulk cargo handling, Fuel depots | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Oslo. 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.
Sjursoya handles container, ro-ro, dry bulk and petroleum cargo.
Winter months average around minus 2 C, and three out of four January days are below freezing, so outdoor equipment should tolerate low temperatures.
The waterfalls of the Akerselva powered some of Norway's first modern industry in the 1840s, and the city's population grew from about 10,000 in 1814 to 230,000 by 1900.
The city is a hub of Norwegian trade, banking, industry and shipping, and an important centre for maritime industries, with many of the world's largest shipping companies, shipbrokers and marine insurers based there.
Oslo Gardermoen airport lies 35 km north-east of the city, so air freight and visitors arrive well outside the urban area and then travel by road or rail.
Because shipping and maritime insurance headquarters are concentrated in Oslo, buyers of marine equipment often meet and approve suppliers there even when the vessels or yards are elsewhere in Norway.
“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 Oslo. At a petroleum storage and loading area or methanol handling area, a marking check reads zone, gas group and temperature class on the label and compares them with the operator's classification. Fuel vapours fall under common gas groups, and methanol handling should be checked with the site against the IS-04Z1 target marking.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
Likely candidates are petroleum product storage and loading, methanol and bulk cargo handling, fuel depots. 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.
Largely, yes. The city is a hub of shipping, banking and trade, with many maritime company headquarters, while major process plants and offshore bases lie elsewhere in Norway. Many suppliers meet buyers in Oslo, then arrange site visits and deliveries separately.
Gardermoen airport is 35 km north-east of the city, and sea freight arrives through Oslo's port. Norway is outside the EU customs union, so allow time for customs declarations and confirm any approval requirements for electrical and radio equipment with your forwarder.
Winter months average around minus 2 C and most January days are below freezing, so battery performance and operating range matter. Check the certified ambient temperature range, keep the phone warm between tasks and charge in a safe area. Ask the operator about cold-weather practice.
