Environment
The semi-arid setting has hot, sunny summers and cool, dry winters with strong winds. Crews often drive long distances between sites.
The shale boom of the early 2010s revived the area after the 1980s oil bust, with manufacturing, transport and construction firms largely serving the energy industry. Zone 1 work arises in the surrounding fields at wellsites, tank batteries, compressor stations and gas plants rather than in the cities themselves. If you are specifying an IECEx smartphone for Midland and Odessa, Texas, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Midland and Odessa, Texas: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Midland Odessa. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The semi-arid setting has hot, sunny summers and cool, dry winters with strong winds. Crews often drive long distances between sites.
Midland is described as a major centre of US oil and natural gas production, and Odessa's economy has been driven mainly by the oil industry. Midland International Air and Space Port serves both cities.
Midland International Air and Space Port is located between the two cities and gives direct access for visiting engineers, while general aviation uses Midland Airpark.
The Midland metro area had about 170,000 residents and the combined Midland-Odessa area about 340,000 at the 2020 census, and Midland recorded the lowest US unemployment rate in 2014 at 2.3 percent.
Midland has a hot semi-arid climate with about 13.5 inches of rain a year, highs above 90 degrees Fahrenheit on roughly 115 afternoons and 100 degrees or more on about 24.
Winters are cool to mild but lows reach freezing or below on about 58 mornings a year, so equipment must handle both heat and occasional frost.
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 Midland and Odessa, Texas. Large producers and oilfield service companies based in Midland and Odessa often work in other countries as well. IECEx gives them a shared international reference, a certificate of conformity with a schedule of conditions to read. For the IS-04Z1 it is a target in progress; nothing has been issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are wellsites and tank batteries, drilling rigs, compressor stations, gas processing plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Midland International Air and Space Port sits between the two cities and is the closest airport; most visitors connect through a larger Texas hub. Allow for long road transfers because the Permian Basin covers about 86,000 square miles.
Oilfield sites are spread over a large area with wellpads, tank batteries and gas processing plants, so lone-worker and coverage requirements often matter as much as area classification. Confirm classified zones and approval rules with each operator.
Producers and service contractors usually buy through their own procurement or field contractors, so the buyer may be a service company rather than the operator. The IS-04Z1 is pre-launch with no certificate. Ask the relevant site operator which approvals apply to contractor devices.
