Industry mix
Factories produce machinery, chemicals, construction materials, food and other goods, so hazard profiles differ by plant.
Dust storms occur in Riyadh and can cut visibility to under 10 m, so filters, port covers and sealed enclosures matter for handheld equipment. Aramco's Riyadh Refinery and manufacturing plants create Zone 1 and Zone 21 areas, but most hydrocarbon sites are in the Eastern Province. This page explains what to look for in an IECEx smartphone for Riyadh, and where the IS-04Z1 stands against that list today.
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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Factories produce machinery, chemicals, construction materials, food and other goods, so hazard profiles differ by plant.
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.
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.
More than 500 foreign companies have moved regional headquarters to Riyadh, alongside banks and major Saudi firms, so many equipment buyers and project teams are based in the capital.
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 Riyadh. Many ministries and firms are headquartered in Riyadh, which means international contractors and EPCs often meet clients here before deploying to a site. IECEx provides a shared reference. The certificate of conformity and schedule of conditions would be reviewed. For the IS-04Z1 these remain targets, not issued documents.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 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.
