The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Port Arthur, Texas. Port Arthur's refining and petrochemical operators include globally owned companies, so a procurement reviewer may expect certificate evidence that is portable across their international sites. A dual ATEX and IECEx route is designed for that. The IS-04Z1 certification is in progress, and no certificate has been issued.

Questions · Port Arthur
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Port Arthur 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 ATEX and IECEx mobile phone in Port Arthur cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Port Arthur, Texas would use it?
Likely candidates are refinery process units, petrochemical plants, tank farms, marine terminals. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
How far is Port Arthur from major airports and ports?
The city is about 90 miles east of Houston, the usual gateway, and lies on the west side of Sabine Lake. Confirm customs and site delivery arrangements with your freight forwarder and the plant's receiving contact.
What hazardous areas exist at a refinery and cracker complex?
Process units, tank farms, loading jetties and crackers all have classified areas for flammable gas and vapour, and the operator defines their extent. Request the area classification drawings and the site's equipment rules before any visit.
Do large Port Arthur refineries use formal supplier onboarding?
Motiva's website refers to supplier resources and an SAP Ariba platform, so formal onboarding is likely at large operators. Equipment approval is a separate matter. The IS-04Z1 has no certificate yet. Confirm requirements with the site operator before approaching procurement.
