Ex-Proof Smartphone in Finland
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for the refinery and polymer plants at Kilpilahti, the metal and chemical parks on the Bothnian coast and the mill and mine sites where a winter round is measured in kilometres. This page explains what to look for in an Ex-proof smartphone for Finland, and where the IS-04Z1 stands against that list today.

WhereFinland
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Finland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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.
The route · specification
Specifying an Ex-proof smartphone for Finland
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 · Finland
Frequently asked questions
Can we buy an Ex-proof smartphone 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 smartphone in Finland cost?
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.
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.
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.
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.
