France: infrastructure
Nuclear power produces around 70% of France's electricity from 56 active reactors in 2023, so large plant outages bring many contractors to a small number of sites.
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 Ex-proof mobile 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. 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.

Le Havre is France's second-largest commercial port by tonnage and its largest for containers, managed since 2008 by the state agency Grand Port Maritime du Havre, a key entry point for imported equipment.
Hydropower has 20 GW of installed capacity and supplies around 10% of French electricity, and renewables provided 26% of national consumption in 2022.
The Lacq gas field in Nouvelle-Aquitaine was discovered in 1950 and began production in 1958; its sour gas comes from about 4,000 metres depth.
“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 France. On a French platform a marking check would compare the device's equipment category, gas group and temperature class with the zone plan. Hydrogen service around industrial gas networks may need group IIC, whereas fuel areas may sit in other groups, depending on the operator's classification. The IS-04Z1 target is II 2 G Ex ib IIC T4.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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 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.
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.
The Fos-sur-Mer and Marseille coast combines a gas terminal, steel, chemistry and oil industries, and the country also has many nuclear and hydro sites. Details of individual plants and zones come from each operator, so request their site layout and approval procedure.
Yes, as an EU member France applies ATEX Directive 2014/34/EU to equipment and zoning under Directive 1999/92/EC. Zone 1 or Zone 2 devices should carry CE and Ex markings with instructions in French. Operators usually add their own approval and permit rules.
Android lets the interface language be set per user, and a fleet can be managed through EMM or MDM. Confirm the exact language support and any locked configuration on the datasheet. Contractor crews often prefer a common set-up agreed before a shutdown.
