Corporate centre
Twenty-three of the 24 ministries and firms such as SABIC and STC are headquartered here, so many buyers and contractors are based in Riyadh even when classified areas are elsewhere.
Riyadh is Saudi Arabia's capital and its administrative and commercial centre, with almost one-third of the country's factories. Aramco's Riyadh Refinery and manufacturing plants create Zone 1 and Zone 21 areas, but most hydrocarbon sites are in the Eastern Province. If you are specifying an intrinsically safe mobile phone for Riyadh, 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 Riyadh: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Riyadh: Refinery process units, Chemical and manufacturing plants, Industrial plant dust areas (Zone 21) | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Riyadh. 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.
Twenty-three of the 24 ministries and firms such as SABIC and STC are headquartered here, so many buyers and contractors are based in Riyadh even when classified areas are elsewhere.
Summer highs near 44 C and occasional severe dust storms.
Riyadh sits on the eastern Najd plateau beside Wadi Hanifa at an average elevation of about 600 m, so it is inland, with no sea-air corrosion unlike the coastal industrial cities.
The city had around 7 million residents in 2022, the largest population in Saudi Arabia, so contractors, service companies and specialist suppliers are concentrated here.
Winters can be surprisingly cold, with a January average low of about 7 C, and most of the little rain falls in March and April, so the temperature range is wide.
The Communications, Space and Technology Commission in Riyadh issues radio type-approval certificates; they are renewed every two years and European test documents are accepted.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Riyadh. Where a Riyadh plant has a gas hazard, such as at the refinery's process units, a handheld intrinsically safe handset suits inspection rounds and turnarounds. It lets staff log defects and photograph equipment without carrying a separate camera. The IS-04Z1 is designed for gas atmospheres and has a 50 MP camera.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are refinery process units, chemical and manufacturing plants, industrial plant dust areas (zone 21). 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.
Rarely, but winters are cooler than many expect, with a January average low around 7 C. The bigger issue is summer heat. Check the datasheet operating range and avoid leaving devices in vehicles; the plant operator may set its own limits.
Yes. Dust storms can cut visibility to under 10 m, so a sealed device with a stated ingress protection rating and good port covers is sensible. Dust ingress and combustible dust in a plant are different issues; follow the operator's dust-zone classification for hazardous areas.
Not necessarily. Many buyers and contractors are based in Riyadh even when the classified areas are elsewhere, because most hydrocarbon sites are in the Eastern Province. Ask where the device will be used, and check the classification for that site, not for the city of purchase.
