France: rules and approvals
ATEX has two equipment groups, Group I for mining and Group II for surface industries, and CE plus Ex marking lets compliant equipment be sold anywhere in the EU, including France.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, aimed at the refineries, chemical platforms and LNG terminals that make up the French Seveso estate. If you are specifying an intrinsically safe cell phone for France, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for France: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in France. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS France market guide.

Fos-sur-Mer lies about 50 km north-west of Marseille on the Mediterranean coast, west of the Etang de Berre, and hosts a major port development run by the Autonomous Port of Marseille.
Fos-sur-Mer's port includes container terminals and a methane terminal, and its waterside industrial zone attracts steel, chemical and oil industry sites, making it a typical mixed-hazard industrial coast.
In 2022 France announced plans to build six new reactors, reversing a 2014 plan to reduce nuclear supply, which points to long-running construction and maintenance work.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In France. A grand arrêt on a French refinery or chemical platform puts large contractor crews through many zones in a short window. An intrinsically safe handheld lets inspectors photograph, record and sign off at the point of work. That is the design intent; the device is not yet certified.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
The market guide for France covers Gonfreville-l'Orcher, Port-Jérôme, Donges, Montoir-de-Bretagne, among others. Site-level pages are linked below.
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.
French is generally expected for instructions and safety documentation at French sites, and ATEX user instructions are typically required in the language of the destination country. International operators may also accept English. Ask the site contact which language they require for contractor equipment files.
Large reactor outages bring many contractors at once, so site access, induction and equipment registration can be tightly scheduled. Nuclear sites also have conventional hazardous areas, for example for hydrogen and fuel stores, so agree device approval early with the plant's safety office.
Zones and rules are set by the site operator and can differ between units on the same platform. A device would need a marking suitable for each zone it enters. Check the zone plan and permit rules with the platform operator before carrying a handset in.
