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.
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 sets out how a rugged smartphone supply route to Finland will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. A rugged smartphone for Finland cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Finland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Finland market guide.
About 2.8 million Finns rely on district heating, so combined heat and power plants and fuel handling sites exist in nearly every town.
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.
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.
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.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Finland. Finnish winters are long, cold and wet, and sites such as the mines in Kainuu and Lapland are remote. IP68 sealing helps against water and dust ingress, and the 4,000 mAh battery is meant for long rounds. IP68 is an ingress rating only; it gives no explosion protection, which must come from certification. Cold-weather battery behaviour should be tested.
Supply of the IS-04Z1 to Finland starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.

Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.

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.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.

Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
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.
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.
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.
