Short answer. An Ex-proof mobile 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.

Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about Czech Republic that matters for portable equipment

Czech Republic: logistics and access

State operator MERO finished expanding the Transalpine pipeline at the end of 2024, delivering up to 8 million tonnes of oil a year, with the central oil depot at Nelahozeves as a key storage point.

Czech Republic: industry on the ground

The country has two refineries, both owned by Česká rafinérská, including the Litvínov refinery, so Litvínov and Kralupy are the best-known flammable-liquid processing sites.

Czech Republic: who works there

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.

Czech Republic: infrastructure

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.

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 Czech Republic. A marking check at a Czech plant would read the certificate number, the issuing body and the complete marking string, which will be published so they can be checked. The target is II 2 G Ex ib IIC T4, with Zone 21 dust in the same programme, which matters at a fertiliser or coking site where powder and gas areas are close.

Questions · Czech Republic

Frequently asked questions

Can we buy an Ex-proof mobile phone in Czech Republic today?

Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.

What does an Ex-proof mobile phone in Czech Republic cost?

No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 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.

Are Czech refineries covered by ATEX rules for handheld devices?

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.

What language should Czech site documents be 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.

Why does the issuing notified body matter to Czech buyers?

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.
