The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for Czech refineries, chemical plants, tank farms and coke ovens rather than for a catalogue. The Ingolstadt-Kralupy-Litvínov pipeline can bring crude oil from Germany and can be connected to the Transalpine pipeline, so crude arrives through pipeline terminals rather than seaports. Distribution partners for Czech Republic are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Czech Republic 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Czech Republic. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Czech Republic market guide.
The Orlen Unipetrol group includes refineries and plants at Litvínov and Kralupy nad Vltavou, Paramo at Pardubice and Kolín, Spolana at Neratovice, and two research centres, and it is the only crude oil processor in the country.
The Gazela pipeline connects Czech gas supply through Germany at Brandov or Rozvadov and through Slovakia at Lanžhot, so compressor and metering stations sit near the borders.
In 2022 electricity production was 78.8 TWh, of which 53.6% came from fossil fuels, mostly lignite, and 40.95% from nuclear, so coal-handling plants and power stations are typical dust and gas sites.
ATEX equipment is split into Group I for mining and Group II for surface industries, which matters in a country with coal mining as well as refining and chemicals.
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 Czech Republic. Within the Czech Republic ATEX decides acceptance, so IECEx is useful mainly where Orlen Unipetrol, Synthos, Deza or Třinecké železárny work with non-EU contractors or share specifications with sites abroad. The certificate of conformity and schedule of conditions are read alongside the ATEX file. Both are in progress, and no certificate has been issued.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Czech Republic. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
The market guide for Czech Republic covers Litvínov and Záluží, Kralupy nad Vltavou, Neratovice, Valašské Meziříčí, among others. Site-level pages are linked below.
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 Czech Republic.
The Czech Republic is an EU member, so ATEX Directive 2014/34/EU applies to equipment and employers zone workplaces under Directive 1999/92/EC. Refineries such as Litvínov typically also have internal device approval and permit-to-work procedures, so ask the HSE office before bringing phones in.
Czech is the usual site language, and ATEX user instructions are typically expected in the local language of the destination. A Czech-language instruction sheet with the certificate pack often speeds up acceptance. Ask the operator whether it also accepts English documentation for contractors.
FTZÚ in Ostrava-Radvanice is notified body 1026, and Czech engineers recognise it on an Ex certificate, so buyers often ask which body issued one before anything else. The certificate number, issuing body and marking string will be published for checking. No certificate exists yet, as certification is in progress.
