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 Baytown, Texas (ExxonMobil Baytown complex). A reviewer at the Baytown complex would usually expect NEC-based Class and Division or Zone evidence, yet ExxonMobil, Chevron Phillips Chemical and Covestro also work with international EPCs carrying ATEX or IECEx paperwork. A dual route is designed to help those contractors. Both remain in progress for SAMS and none is issued.

Questions · Baytown Refinery
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Baytown Refinery today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an ATEX and IECEx smartphone in Baytown Refinery cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
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 Baytown, Texas (ExxonMobil Baytown complex) would use it?
Likely candidates are refinery process units, ethylene cracking units, chemical plant units, ship channel storage and docks. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Baytown, Texas (ExxonMobil Baytown complex)?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Baytown, Texas (ExxonMobil Baytown complex).
Why is the Houston Ship Channel relevant for logistics?
The complex lies along the channel with marine access, plus road links to Houston about 25 miles away. Confirm shipping and customs arrangements for equipment.
How are Ex devices marked and approved for Baytown?
US sites use NEC Class and Division and IEC Zone marking; confirm which the site accepts and the gas group, temperature class, and any contractor approval process.
Will project activity affect equipment needs?
A blue hydrogen facility is under construction, according to encyclopaedic text not checked with ExxonMobil, so project and contractor activity may continue alongside operations. Hydrogen could affect the gas group required. Ask the operator or its contractors for the marking and approval requirements for new areas.
