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.

Questions · Borlänge
Frequently asked questions
Can we buy an Ex-proof mobile phone in Borlänge 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 Ex-proof mobile phone 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.
How do I become a SAMS distributor for Borlänge?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Borlänge.
How do I reach Borlänge for site work?
Dala Airport is 8 km south-east with limited services, and Stockholm Arlanda is 214 km away, so many visitors arrive by train or road. Plan equipment delivery by road freight and confirm gate procedures with the site.
What hazardous areas arise at a steelworks such as Domnarvet?
Steel works typically involve process gases, fuel gas and oxygen systems, hydraulic oil, coating lines, and dust from coal, ore or scale. The operator defines gas and dust zones, so ask SSAB for its classification drawings and portable-device rules before bringing equipment.
Will cold Dalarna winters affect the battery of a handheld on outdoor rounds?
Winters in Borlänge are cold, with January averaging around -1 degrees C, so cold-tolerant batteries and gloved operation matter for outdoor rounds. The IS-04Z1 has a 4,000 mAh battery, but cold performance has not been published for it. Ask for the datasheet before specifying winter use.
