IECEx Smartphone in Borlänge
The town lies on the Dalälven river downstream of the confluence of the Österdalälven and Västerdalälven, and it is the largest urban centre in the province of Dalarna, with about 44,900 residents in 2020. Steel and paper processing involve fuel gas, chemicals and fine dust, so Zone 1 and Zone 21 classification can apply in plant areas. If you are specifying an IECEx smartphone for Borlänge, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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.

More about Borlänge that matters for portable equipment
Borlänge: people and language
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.
Borlänge: industry on the ground
Borlänge has long been an industrial town around the Domnarvet iron and steel works, now SSAB, and the Kvarnsveden paper mill, owned by Stora Enso.
Borlänge: background
Construction of the Domnarvet ironworks began in 1872, and a railway between Falun and Ludvika via Borlänge opened in 1875, making the town a strategic junction for the works.
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.
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 Borlänge. Borlänge's two large works are served by outside maintenance and project contractors, some working across several countries. An IECEx certificate of conformity, read with its schedule of conditions, gives such visitors a common reference. For the IS-04Z1 that certificate is still in progress, so nothing can be presented to a Dalarna works yet.

Questions · Borlänge
Frequently asked questions
Can we buy an IECEx 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 IECEx smartphone in Borlänge cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
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 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.
