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 Bakken, North Dakota (Williston Basin). Bakken operators include national companies that may not ask for ATEX or IECEx on a US lease, but visiting international contractors and equipment programmes sometimes do. A dual route is designed to give such reviewers a recognisable certificate set. For the IS-04Z1 this is in progress; no certificate has been issued.

Questions · North Dakota Bakken
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in North Dakota Bakken 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 North Dakota Bakken 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 Bakken, North Dakota (Williston Basin) would use it?
Likely candidates are drilling rigs, wellsites and tank batteries, gas gathering and processing, crude loading facilities. 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 Bakken, North Dakota (Williston Basin)?
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 Bakken, North Dakota (Williston Basin).
How do I get to Williston from overseas?
Williston Basin International Airport opened in 2019 and is the closest airport, usually reached through a larger US hub. Allow for road transfers and winter weather delays, and agree site access in advance.
Are Bakken sites very remote?
Many wellpads and processing plants are spread over rural plains, with Williston acting as the main service base. Confirm network coverage, emergency contact procedures and lone-worker policies with the operator, because coverage and response times differ from city sites.
Which regulator sets the rules for oil and gas work here?
The North Dakota Department of Mineral Resources, Oil and Gas Division oversees oil and gas activity. It does not approve phones. Equipment requirements generally come from operators and field service contractors, and SAMS holds no certificate yet, so ask the relevant operator what it would accept.
