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.

Field notes · Riyadh
More about Riyadh that matters for portable equipment
Riyadh: geography and layout
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.
Riyadh: people and language
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.
Riyadh: climate and equipment wear
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.
Riyadh: rules and approvals
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.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Riyadh. Riyadh buyers include corporate HSE and procurement teams for companies headquartered here, even when the classified areas are elsewhere. They would expect certificate evidence for both ATEX and IECEx that traces to the marking. The IS-04Z1 has no certificate yet; certification is in progress, so any purchase decision should wait on documents.

Specifying an ATEX and IECEx smartphone for Riyadh
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Riyadh
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Riyadh 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 ATEX and IECEx smartphone in Riyadh 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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Riyadh would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Does the Riyadh climate stress phones at low temperature?
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.
Does dust in Riyadh matter for phone selection?
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.
Are Riyadh buyers mostly purchasing for Riyadh sites?
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.
