The IS-04Z1 is an eigensicheres Smartphone designed to ATEX 2014/34/EU for Zone 1 and Zone 21, built for the chemical parks, refineries and pharmaceutical plants where most German Ex-Schutz work happens. This page explains what to look for in an Ex-proof mobile phone for Germany, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Germany: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Germany: Ludwigshafen, Leverkusen, Marl | Classified by the site operator |
An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Germany. 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 Germany market guide.
BASF says its Ludwigshafen Verbund site covers about ten square kilometres, makes it the world's largest integrated chemical complex, and has 125 production plants, with roughly a third of BASF employees worldwide based there.
Manufacturers may self-certify ATEX Category 3 equipment with a technical dossier including a user manual in the local language, while Category 1 and 2 generally need a notified body.
Norway supplied the largest share of both Germany's gas and crude oil imports in 2025, and German LNG terminals accounted for 10.3% of natural gas imports, so LNG import sites are a new classified-area category.
Germany plans to phase out coal-fired electricity generation by 2038 at the latest and aims for renewables to supply at least 80% of gross electricity consumption by 2030.
“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 Germany. A German marking check would compare the device's category, gas group, dust capability and temperature class with the zone documentation for each plant. Chemical-park gas service can involve hydrogen and other groups, so IIC capability helps. The IS-04Z1 target is II 2 G Ex ib IIC T4, and it remains a target until certification is complete.
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 Germany covers Ludwigshafen, Leverkusen, Marl, Frankfurt Höchst, 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.
German LNG terminals supplied about 10.3% of natural gas imports in 2025, and crude, products and coal arrive through ports and pipelines. Individual terminal locations and rules change, so confirm the current list and each operator's contractor requirements before planning work.
Lignite is mined in North Rhine-Westphalia, Saxony and Brandenburg and burned at nearby power plants, so coal dust, conveyor and bunker areas are typical dust zones. Choose devices with a dust group marking suited to the area classification, and check with the operator.
Acceptance is the decision of the operator and its approved inspection body. ATEX is the usual reference for equipment in the EU, and IECEx papers may support a review. Ask the site's explosion protection officer which evidence they require before ordering.
