Switzerland: projects and investment
The Mantelerlass, passed on 29 September 2023, sets a target of 35 TWh a year from new renewable technologies by 2035, compared with about 6 TWh a year in 2022, which implies major construction work.
The IS-04Z1 is an intrinsically safe Android handset designed for solvent and powder atmospheres, from a production building in Basel or Visp to a loading rack at Cressier and a digester hall at a cantonal wastewater works. If you are specifying an ATEX and IECEx cell phone for Switzerland, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Switzerland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Switzerland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Switzerland market guide covers.
The Mantelerlass, passed on 29 September 2023, sets a target of 35 TWh a year from new renewable technologies by 2035, compared with about 6 TWh a year in 2022, which implies major construction work.
Hydraulic power was used instead of steam in Swiss industry because of the mountainous terrain and lack of coal, which explains the concentration of hydro stations and tunnels in the Alps.
Switzerland produces no fossil fuels and imports petroleum, so refining and bulk fuel handling is limited, while storage depots and distribution terminals are the main flammable-liquid sites.
The three Rhine ports around Basel handle about six million tonnes and over 120,000 containers a year, roughly 10% of Swiss imports and a third of the country's mineral oil products.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Switzerland. A Swiss procurement or HSE reviewer in the Basel pharmaceutical cluster would expect certificate evidence recognised under the European framework, with the marking, ambient range and conditions of use checked in detail. A dual ATEX and IECEx route also helps international groups and contractors working at sites such as Visp. No certificate exists yet for the IS-04Z1.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
The market guide for Switzerland covers Basel and Schweizerhalle, Visp, Monthey, Kaisten and the Fricktal, among others. Site-level pages are linked below.
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.
Switzerland is not an EU member, but it generally aligns its equipment rules with European requirements, so ATEX-marked devices are commonly accepted. Confirm the current requirement and any Swiss conformity marking with the site operator or your importer before ordering.
German, French and Italian are all national languages depending on the canton, and many industrial sites also work in English. Ask the operator which language it requires for instructions and certificates, and provide the declaration of conformity together with the Ex marking details.
IP68 sealing and a rugged build are aimed at a cleaned plant rather than a rained-on one, but your cleaning agents and routine must be checked. Test a unit with your own procedure and confirm compatibility with the site's validation team.
