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 smartphone in Port Arthur 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 Port Arthur 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 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.
How do I become a SAMS distributor for Port Arthur, Texas?
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 Port Arthur, Texas.
Why is humidity a bigger issue at Port Arthur than at other Texas sites?
Port Arthur is among the most humid places in the contiguous United States, with morning humidity near 90 percent. Condensation inside poorly sealed devices is a real risk, so choose sealed housings and follow the maker's care instructions.
How do turnarounds affect equipment demand at Port Arthur?
Large refineries run planned turnarounds that bring thousands of contractors on site for a limited period. Operators typically plan equipment and induction well in advance, so contact the site's maintenance planners early and confirm approval requirements.
How do hurricanes affect handheld planning on the Gulf Coast?
Port Arthur is hot and humid with hurricane exposure, which shapes turnaround scheduling. A rugged IP68 phone helps with water and dust, and managed enrolment lets a contractor lock or recover devices when a site closes. Store and charge devices in safe areas away from classified plant.
