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 Yanbu Industrial City. Yanbu's refineries include joint ventures such as SAMREF and YASREF with international partners, so reviewers often expect both ATEX and IECEx evidence. A dual route helps contractors who work across partner plants. The IS-04Z1 has no certificate yet; certification is in progress.

Questions · Yanbu
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Yanbu today?
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.
What does an ATEX and IECEx mobile phone in Yanbu 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 Yanbu Industrial City would use it?
Likely candidates are refinery process units, petrochemical plants, crude and product storage and loading, 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 is Yanbu connected to the east of the country?
The East-West crude pipeline of about 1,200 km can deliver up to 7 million barrels a day to Yanbu from the Eastern Province. Road and air links also exist, but heavy equipment normally arrives through the port; confirm routing and permits with the client.
Which part of Yanbu has the classified areas?
Mostly the industrial city in the south, with its refineries and petrochemical plants, and the port about 20 km south of Yanbu town. Yanbu Al-Bahr in the north is the main residential and commercial area, so offices and hotels are separate from the plants.
Does coastal exposure affect handset choice at Yanbu?
Yes. With a hot desert climate, a July record of 51 C and a Red Sea coast, sealed equipment is favoured. IP68 helps against dust and splash, but heat and salt exposure should be checked against the datasheet. Ingress protection does not replace the Ex marking needed for classified areas.
