Explosion-Proof Mobile Phone in Sweden
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for refinery and cracker rounds on the west coast, mill and recovery boiler areas inland, and winter shifts in the north where a device is handled through two layers of glove. This page explains what to look for in an explosion proof mobile phone for Sweden, and where the IS-04Z1 stands against that list today.

WhereSweden
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Sweden: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Sweden
More about Sweden that matters for portable equipment
Sweden: infrastructure
In 2023, 98% of Swedish electricity generation came from renewables and nuclear, and over 20% of generation was exported to the rest of Europe, so hydro and nuclear sites dominate electricity work.
Sweden: industry on the ground
Sweden had the EU's highest share of renewable energy for heating and cooling at 69% in 2022, so biomass boilers and district heating plants with combustible dust are common.
Sweden: who works there
Preem sells fuels, heating oil and lubricating oils to companies and individuals in Sweden and Norway, and since 2026 its parent company has been part of VARO Energy, so site procedures may follow the new group.
The term · explosion proof
What “explosion proof” means for a smartphone
“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 Sweden. Explosion-proof is the everyday phrase, yet Swedish sites hold four separate worlds: coastal refining, specialty chemicals, mining and steel, and mills. Flameproof Ex d suits heavy enclosures, while the IS-04Z1 uses intrinsic safety to limit the energy of a handheld. Which concept applies depends on the area being entered.

Specifying an explosion proof mobile phone for Sweden
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 · Sweden
Frequently asked questions
Can we buy an explosion proof mobile phone in Sweden today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an explosion proof mobile phone in Sweden 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
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.
Which sites in Sweden does this cover?
The market guide for Sweden covers Lysekil, Gothenburg river bank, Stenungsund, Nynäshamn, 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 Swedish refineries require ATEX certified phones?
Sweden is an EU member, so ATEX Directive 2014/34/EU applies to equipment and Directive 1999/92/EC to zoning. Zone 1 and Zone 2 devices should carry CE and Ex markings. Refineries such as Lysekil typically add their own permit and device registration rules, so ask the HSE office.
What language should device documents be in for Swedish sites?
Swedish is the working language but English is widely used at international industrial sites. ATEX instructions are typically expected in the language of the destination country, so confirm with the operator whether Swedish documents are needed. Bring the declaration of conformity and certificate.
How cold can the IS-04Z1 be used at a northern Swedish site?
A rugged build covers low temperature and thermal shock, but the certified ambient range is a certificate parameter, published with the datasheet. Certification is in progress. Check the lower limit against the coldest conditions at the mine or steelworks before specifying.
