Ex-Proof Smartphone in Borlänge
Dalarna University was founded in 1977 as a joint college for Falun and Borlänge, and the town hosts the head office of the Swedish Transport Administration, Trafikverket. Steel and paper processing involve fuel gas, chemicals and fine dust, so Zone 1 and Zone 21 classification can apply in plant areas. This page explains what to look for in an Ex-proof smartphone for Borlänge, and where the IS-04Z1 stands against that list today.

Site conditions at Borlänge: what wears and what limits equipment
Climate
Humid continental climate with cold winters (January averages about -1 degrees C), so outdoor rounds in winter call for cold-tolerant batteries and gloved operation.
Field notes · Borlänge
More about Borlänge that matters for portable equipment
Borlänge: industry on the ground
SSAB describes its Borlänge works, established in 1878, as its largest strip rolling system, making hot-rolled and cold-rolled high-strength steel for automotive, heavy-duty transport, lifting and container uses, with around 1,700 employees.
Borlänge: projects and investment
The four blast furnaces and two Kaldo converters at Domnarvet were shut down in 1981, and the site since then has developed around its hot strip rolling mill.
Borlänge: infrastructure
SSAB's industrial area lies in downtown Borlänge, the Dal river flows through the site, and the works contain around 30 km of railroad track.
Borlänge: logistics and access
Borlänge Central is a railway junction for routes toward Falun, Mora and Ludvika and links to Gävle and Stockholm, and Dala Airport lies 8 km south-east, with Arlanda 214 km away.
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 Borlänge. A marking check around Borlänge would match the equipment marking to the zone given on the operator's classification drawings. Gas-side areas such as fuel and process gas systems may be Zone 1, while dust-generating process areas may be Zone 21. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, which addresses gas only.

Specifying an Ex-proof smartphone for Borlänge
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

Questions · Borlänge
Frequently asked questions
Can we buy an Ex-proof smartphone in Borlänge today?
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.
What does an Ex-proof smartphone in Borlänge 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 areas at Borlänge would use it?
Likely candidates are fuel and process gas systems, chemical and oil storage, dust-generating process areas (zone 21). Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Is Swedish winter weather a problem for devices at Borlänge?
Inland Dalarna can be cold in winter, so batteries and touchscreens may perform less well outdoors. Typically users keep spare batteries warm and check the device's rated temperature range against site conditions, while mills and steelworks may require protective cases.
Does a paper mill like Kvarnsveden have explosive atmospheres?
Mills typically have combustible dust from wood and fibre, flammable gases in energy and chemical recovery areas, and solvent stores. Each site classifies its own areas, so ask the mill's safety team for zone drawings and whether handheld devices are permitted.
How do contractors get a phone into the SSAB or Stora Enso works at Borlänge?
Large works here run their own contractor induction and permit-to-work systems, so access to classified areas is arranged through each operator. A phone would normally be listed and approved as part of that process. Ask the operator's HSE or procurement team what device evidence it requires.
