Finland: infrastructure
About 2.8 million Finns rely on district heating, so combined heat and power plants and fuel handling sites exist in nearly every town.

IECEx Mobile Phone 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 IECEx mobile phone for Finland, and where the IS-04Z1 stands against that list today.

Field notes · Finland
More about Finland that matters for portable equipment
Finland: industry on the ground
Bioenergy and waste make up 33.6% of total energy supply and peat 2.7%, with Finland one of the last countries still burning peat, which brings fuel-dust handling into power and heat plants.
Finland: climate and equipment wear
Energy use per capita is the highest in the EU, partly because of energy-intensive industry, a cold climate and long distances, so winter operation of handheld equipment is a normal planning point.
Finland: rules and approvals
The Finnish Safety and Chemicals Agency, Tukes, monitors safety in technology, chemicals and hazardous materials, with divisions for facilities and mines and for products and equipment, and is Finland's competent authority for REACH, CLP and Seveso III.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Finland. Finland hosts operators such as Neste and Borealis Polymers, and large plants draw in international contractors for shutdowns. For them the international scheme is a familiar reference: a certificate of conformity names the equipment, and its schedule of conditions lists any special conditions of use. IECEx certification for the IS-04Z1 is in progress, so nothing can be cited yet.

Specifying an IECEx mobile phone 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 IECEx 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 IECEx mobile phone 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
Do Finnish biomass and peat plants have different explosion risks from refineries?
Yes, because fuel dust from wood, biomass and peat is combustible, so dust zones such as Zone 21 and Zone 22 matter alongside gas zones. Choose devices with dust group marking suitable for the site's classification drawings and the operator's own requirements.
How does Finland's cold climate affect Ex handheld devices?
Winter temperatures can fall well below the minimum rating of ordinary electronics, and battery capacity drops in the cold. Check the lowest rated ambient temperature on the certificate, glove-friendly touch operation and whether charging must happen indoors outside the classified area.
Do contractors at Kilpilahti need their own approved devices?
Gate procedures and contractor rules are set by the operator and the site authority, so requirements vary. A contractor would normally be asked for evidence that a device suits the zones it enters. Check the rules with the site before bringing any device in.
