United States: industry on the ground
The Permian also yields potash, mined by the room-and-pillar method in Lea and Eddy counties in New Mexico, which adds mining and mineral-dust hazards to the oil and gas activity.

NEC 500 Class I Division 1 Smartphone Distributor in United States
The IS-04Z1 is built for people who work inside classified locations at American refineries, gas plants, terminals and wellsites, and for the HSE and IT teams who decide what goes through the gate. US workplace rules accept electrical equipment in explosive atmospheres only if it is approved by an OSHA-recognised NRTL, and OSHA states that the NRTL's specific mark is required, so CE and ATEX do not count. An NEC 500 Class I Division 1 smartphone distributor in United States would carry the IS-04Z1 to these buyers once certification completes.

United States: rules and approvals
For Zone approval the ANSI/UL and ANSI/ISA 60079 series apply, and ordinary-location electrical safety standards such as ANSI/UL 61010 must also be met.
United States: geography and layout
The Permian Basin in West Texas and south-eastern New Mexico covers more than 86,000 square miles and extends about 250 miles wide and 300 miles long, so sites are spread over a very large area.
United States: industry on the ground
The Permian is the highest-producing US oil field, averaging 4.2 million barrels of crude a day in 2019, with Midland, Odessa and San Angelo serving as headquarters towns.
The term · NEC 500 Class I Division 1
What “NEC 500 Class I Division 1” means for a smartphone
North America classifies hazardous locations by Class and Division under the National Electrical Code (NEC 500, with NEC 505 as the zone-based alternative); Canada uses the Canadian Electrical Code. Class I Division 1 is the closest counterpart to Zone 1 for flammable gases and vapours. Equipment must be listed by a nationally recognised testing laboratory.
NEC 500 Class I Division 1 is one of the four routes in the IS-04Z1 certification programme. It is in progress and no listing has been issued.
In United States. In the US the working language is Class and Division, where Zones are an alternative; the IS-04Z1 targets Zone 1 and Zone 21 and also pursues Class I Division 1. A reviewer should read both together: Class I covers gas, Division 1 where ignitable concentrations are normally present, and the listing is in progress, so check the final marking.

Distributing the IS-04Z1 in United States
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for United States yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in United States.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · United States
Frequently asked questions
Can we buy an NEC 500 Class I Division 1 smartphone in United States 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 NEC 500 Class I Division 1 smartphone in United States 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.
Will the IS-04Z1 be listed for Class I Division 1?
NEC 500 Class I Division 1 is part of the certification programme and is in progress. No listing has been issued.
Which sites in United States does this cover?
The market guide for United States covers Permian Basin, Houston Ship Channel, Beaumont and Port Arthur, Lake Charles and Calcasieu, among others. Site-level pages are linked below.
How do I become a SAMS distributor for United States?
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 United States.
Is IECEx or ATEX certification enough for US hazardous locations?
Not on its own. US workplace rules accept equipment approved by an OSHA-recognised NRTL and marked accordingly, and ATEX or IECEx certificates are not accepted in their place. Manufacturers usually need a separate US listing, so check the NRTL mark and the Class, Division or Zone marking on any device.
Do US sites use Class and Division or Zone classification?
Both exist. Article 500 of the National Electrical Code defines the Class and Division system, and Articles 505 and 506 define Zones. Many existing refineries and gas plants are still classified by Division, so confirm which system the area drawing uses before selecting equipment markings.
Can one handset suit both a Permian wellpad and a North Dakota gas plant?
IP68 sealing and a rugged build are aimed at August heat and January cold, and the 4,000 mAh battery at a shift away from the truck. The approved ambient range will come from the certificate, which is in progress, so confirm it for both extremes.
