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 Sarnia (Chemical Valley). A reviewer in Sarnia's Chemical Valley, with refineries run by Imperial Oil, Suncor and Shell and chemical producers such as NOVA Chemicals and Lanxess, would expect certificate evidence suited to process units and loading. A dual ATEX and IECEx route helps firms that serve several of these owners. No certificate has been issued for the IS-04Z1.

Questions · Sarnia Refinery
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Sarnia Refinery today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an ATEX and IECEx smartphone in Sarnia Refinery 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.
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 Sarnia (Chemical Valley) would use it?
Likely candidates are refinery process units, petrochemical plants, product storage and loading, pipeline 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.
Is Sarnia a border logistics point?
The Blue Water Bridge and harbour make it a crossing and shipping location, but customs rules change. Confirm clearance arrangements for equipment crossing the border with a customs broker.
How does the lake climate affect equipment in Sarnia?
Lake Huron moderates temperatures but brings humidity and lake-effect snow. Sealed devices, winter ratings and a drying routine help. Confirm site guidance on temperature class and ingress protection.
Does acceptance at one Sarnia plant carry over to the next?
Not automatically. Each operator approves equipment through its own HSE or electrical authority, and neighbouring plants may ask for different documents. A manufacturer certificate would help, but ask every site what it requires. Contractors who move between plants should check this before bringing devices on site.
