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 Baton Rouge. The Baton Rouge refinery and chemical complex, and Dow's operations nearby, use international contractors and licensors who may arrive with IECEx documentation. The target is a certificate of conformity and a schedule of conditions that an engineer can read against a given area. It remains in progress, and operators decide what they accept.

Questions · Baton Rouge
Frequently asked questions
Can we buy an IECEx smartphone in Baton Rouge 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 Baton Rouge 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 Baton Rouge would use it?
Likely candidates are refinery process units, chemical plant units, tank farms, dock and loading facilities. 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.
US Division or IEC Zone marking: which does Baton Rouge accept?
US refineries traditionally use NEC Class and Division, and many now accept IEC Zone-marked equipment. Confirm which scheme and gas group the facility's classification uses and what certification mark it accepts.
Does hurricane season matter for scheduling work in Baton Rouge?
The Gulf Coast has a hurricane season, which can alter work schedules and site access. Confirm schedule risk and weather policy with the operator and contractor.
Does Baton Rouge use Class and Division or Zones?
US plants have traditionally used Class and Division, and Zone-based classification is also used. Which applies depends on the operator's engineering standards for each area. ExxonMobil's engineering and safety teams approve equipment, so confirm requirements with the site operator before specifying.
