Czech Republic: infrastructure
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.

IECEx Cell Phone Supplier in Czech Republic
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. Buyers searching for an IECEx cell phone supplier for Czech Republic can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.

WhereCzech Republic
Short answer. An IECEx cell phone for Czech Republic cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Czech Republic
More about Czech Republic that matters for portable equipment
Czech Republic: infrastructure
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.
Czech Republic: rules and approvals
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.
Czech Republic: industry on the ground
Gas use was 9.4 billion cubic metres in 2021 and 7.1 billion in 2023, so gas distribution and industrial gas burners remain widespread across Czech industry.
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 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.

Questions · Czech Republic
Frequently asked questions
Can we buy an IECEx cell phone in Czech Republic 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 IECEx cell phone in Czech Republic 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 sites in Czech Republic does this cover?
The market guide for Czech Republic covers Litvínov and Záluží, Kralupy nad Vltavou, Neratovice, Valašské Meziříčí, among others. Site-level pages are linked below.
How will SAMS supply Czech Republic?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do Czech mines need different Ex equipment from refineries?
Yes. ATEX separates Group I equipment for mining from Group II for surface industries, and methane and coal dust conditions underground differ from refinery gas and vapour. Check the Group marking on any device against the area and the mine operator's own approval process.
How do pipeline terminals in the Czech Republic affect device planning?
Crude arrives by pipeline from Germany and Italy, with storage at depots such as Nelahozeves, so many classified areas are at pumping and storage sites rather than ports. Terminal operators run their own induction and device registration, so schedule approvals early for shutdown work.
Must the instructions be in Czech?
Czech law expects the instructions in Czech, so the manual, safe-use guidance and declaration of conformity are planned in Czech alongside English, with a Czech interface on Android 16. That is planned into the launch rather than translated afterwards. Certification is in progress. Check requirements with your safety officer.
