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 · explosion proof

What “explosion proof” means for a smartphone

“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.

The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.

In Czech Republic. At Litvínov, Kralupy or Třinec, the everyday phrase explosion proof covers many things. Flameproof Ex d suits fixed motors and enclosures, while the IS-04Z1 relies on intrinsic safety so a handheld can be used live near coke ovens, crackers and tank farms. The operator classifies each area, not SAMS.

Sourcing the IS-04Z1 for Czech Republic

Nothing can be bought for Czech Republic today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you at launch.

  1. 01

    Request the datasheet

    The technical specification, marking target and conditions of use, sent by email.

  2. 02

    Ask for the certification schedule

    Which certificates are in progress, in what order, and what is still to be confirmed.

  3. 03

    Evaluate in a safe area

    Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.

  4. 04

    Register for launch

    Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.

Questions · Czech Republic

Frequently asked questions

Can we buy an explosion 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 explosion 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.

Is the IS-04Z1 explosion proof or intrinsically safe?

It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.

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.
