WhereVästerås
Short answer. Västerås has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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 Västerås. A marking check in Västerås must separate gas from dust. Fuel preparation and storage areas for waste, recycled wood and biomass may be Zone 21 dust, whereas boiler fuel and auxiliary systems may be Zone 1 gas. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, covers gas only, so dust areas need separate evaluation.
The route · distribution
Distributing the IS-04Z1 in Västerås
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Västerås yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Västerås.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Västerås
Frequently asked questions
Can we buy an Ex-proof mobile phone in Västerås 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 mobile phone in Västerås 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.
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 Västerås would use it?
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.
How do I become a SAMS distributor for Västerås?
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 Västerås.
Does a Swedish winter matter for phones used outdoors at Västerås?
Winters are cold, with historical lows near minus 36 degrees, so battery life and screen response can suffer outdoors. Typically users keep spare batteries warm and check the device's rated operating temperature range against site conditions.
How do I reach Västerås for a site visit?
Direct trains run from Västerås Central to Stockholm, and Arlanda airport is 111 km away, so most visitors fly to Stockholm and continue by rail or road. Plan equipment delivery by road freight and confirm gate procedures with each site.
Is the IS-04Z1 suitable for dusty biomass fuel areas at a plant like Mälarenergi?
Its target marking, II 2 G Ex ib IIC T4, is a gas marking, and certification is in progress. Biomass and waste fuel handling may be Zone 21 dust, which needs a separate dust-rated marking. Check the operator's classification and ask the plant's HSE team what applies.
