Field notes · Czech Republic

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 · industrial

What “industrial” means for a smartphone

“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.

The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.

In Czech Republic. Contractor crews arrive and leave during shutdowns, which can make handover a weekly event. Android 16 with EMM and MDM lets a device be enrolled, restricted to the applications a site allows, wiped and reissued. The interface is in Czech, and the instructions and declaration are produced in Czech, as Czech law expects.

The route · specification

Specifying an industrial mobile phone for Czech Republic

A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.

Standards edition
The IEC 60079 or national standard edition the certificate was issued against.

Check for the IS-04Z1

Marking target
II 2 G Ex ib IIC T4: a target, not yet a certificate.

Questions · Czech Republic

Frequently asked questions

Can we buy an industrial mobile phone in Czech Republic today?

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.

What does an industrial 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 an industrial phone as well as an Ex phone?

Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and 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.

Is intrinsically safe the same as explosion proof?

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.

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.
