The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Port Arthur, Texas. Motiva, owned wholly by Saudi Aramco since 2017, and other operators around the Sabine-Neches waterway work with international contractors. IECEx gives those teams a certificate of conformity and a schedule of conditions to compare. For the IS-04Z1 it is a target only; nothing has been issued.

Questions · Port Arthur
Frequently asked questions
Can we buy an IECEx smartphone in Port Arthur 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 IECEx smartphone in Port Arthur cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
