Climate
Humid continental climate with cold winters and warm summers, so equipment sees a wide temperature range.
Västerås is a city on Lake Mälaren, 110 km west of Stockholm, with an industrial base that includes ABB and the Mälarenergi combined heat and power plant. ABB's Swedish headquarters is in Västerås, where it produces robots, drive systems and high-voltage equipment, after the electrical manufacturer ASEA concentrated its operations there following early electrification in 1891. This page explains what to look for in an explosion proof smartphone for Västerås, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Västerås: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Västerås: Waste, recycled-wood and biomass fuel handling (Zone 21), Boiler plant fuel and auxiliary systems, Fuel preparation and storage areas | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Västerås. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Humid continental climate with cold winters and warm summers, so equipment sees a wide temperature range.
The city is a logistics centre in the Mälardalen region, about 110 km from Stockholm, which eases delivery and service visits.
Westinghouse Sweden produces nuclear fuel and offers services for boiling water and pressurised water reactors from an industrial area in northern Västerås, with more than 1,000 employees in 2014.
Västerås has a humid continental climate bordering on oceanic, with cold winters, warm summers, a record low of minus 36.5 degrees Celsius in 1875 and a record high of 36.0 degrees in 1966.
Stockholm-Västerås Airport is 7.4 km from the centre with limited routes, and the larger Arlanda airport is 111 km away, with direct train links from Västerås Central to Stockholm.
Mälardalen University has about 16,000 students across Västerås and Eskilstuna, and industries such as Bombardier Transportation and GE Power also operate in the city.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Västerås. At a plant burning waste, wood and biomass, explosion-proof is a catch-all phrase. The real distinction is between dust protection for fuel handling areas and gas protection around boiler auxiliaries. Flameproof Ex d suits fixed equipment, while intrinsic safety suits handheld devices; the operator decides which concept each area needs.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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 intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Likely candidates are waste, recycled-wood and biomass fuel handling (zone 21), boiler plant fuel and auxiliary systems, fuel preparation and storage areas. 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.
Yes, facilities that handle nuclear material usually have strict access and device-control rules in addition to any explosive-atmosphere rules. Such sites typically restrict or log electronics at entry, so contact the operator's security and safety staff well before visiting.
Typical examples are the combined heat and power plant with fuel handling, nuclear fuel fabrication with its own strict safety rules, and electrical and industrial plants with solvents or combustible dust. Each operator classifies its own areas, so ask for zone drawings first.
The climate is humid continental, with cold winters and warm summers, so devices see a wide range. The IS-04Z1 has a 4,000 mAh battery and IP68 rating, but no temperature range has been published here. Ask for the datasheet and confirm limits with the plant operator.
