Field notes · Finland
More about Finland that matters for portable equipment
Finland: background
Neste built Finland's first refinery at Naantali in 1957 and the Porvoo refinery at Sköldvik (Kilpilahti) in 1965, so Naantali and Porvoo are the traditional centres of refining.
Finland: industry on the ground
Finland lacks domestic fossil energy and imports substantial petroleum and natural gas, so refining, fuel terminals and gas-supply sites are mostly import-led rather than field-based.
Finland: industry on the ground
The industrial sector accounted for 53% of total final energy consumption in 2021, well above the IEA average, so process industry sites strongly shape the demand for classified-area equipment.
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 Finland. A marking check at a Finnish site would read the gas group, temperature class and equipment category against the area classification. Hydrocarbon and hydrogen service at Kilpilahti may call for a different group than a pulp mill's dust areas. The IS-04Z1 marking target is II 2 G Ex ib IIC T4; it is a target, not a granted marking.

Questions · Finland
Frequently asked questions
Can we buy an Ex-proof mobile phone in Finland today?
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.
What does an Ex-proof mobile phone in Finland cost?
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.
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 sites in Finland does this cover?
The market guide for Finland covers Kilpilahti, Porvoo, Naantali, Kokkola, Harjavalta, among others. Site-level pages are linked below.
How will SAMS supply Finland?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Does Finland follow ATEX for handheld devices in hazardous areas?
Finland is an EU member, so ATEX Directive 2014/34/EU applies to equipment placed on the market and employers zone workplaces under Directive 1999/92/EC. Operators usually also apply their own permit and device registration processes. Ask the site safety office for its current list.
Where are Finland's main refining and fuel sites?
Neste built refineries at Naantali in 1957 and at Porvoo, in the Kilpilahti area, in 1965. Fuel terminals and gas-supply sites serve the rest of the country. Individual site rules and current operations should be confirmed with the operator before a visit.
Can a phone be used in cold Finnish winter conditions?
The IS-04Z1 is designed for industrial duty with IP68 sealing, but cold performance of any lithium battery needs testing. Ask for the datasheet's operating temperature range and trial a unit on an actual winter round. Site rules on charging and storage in safe areas still apply.
