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.

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.

Questions · United States
Frequently asked questions
Can we buy an NEC 500 Class I Division 1 smartphone in United States today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an NEC 500 Class I Division 1 smartphone in United States cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Will the IS-04Z1 be listed for Class I Division 1?

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 will SAMS supply United States?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What conditions affect devices in the Permian Basin?
The basin is dry and sparsely built, so summer heat, dust and long drives between sites are typical. Check the operating temperature range, dust ingress rating and battery life, and confirm any operator-specific site rules, including permits and gas detection practice, with the company controlling the lease.
What FCC approval does a smartphone need in the United States?
Radio-containing devices such as phones normally need FCC equipment authorisation, either by certification through an approved body or a supplier's declaration depending on the device type. Check the FCC rules and consult an accredited test lab or telecommunication certification body for your product's category.
Does the handset cover Class II dust areas in the US?
The Zone 21 design target covers dust at sulfur handling, coal transfer and solids charging, but certification is in progress and no listing exists. Check which Class and Division the final listing covers against your facility's own classification before use.
