Ex-Proof Smartphone in Najran
About 3.6 million of the industrial city's 6.5 million square metres were reported as fully developed, so new plants are still being added alongside existing ones. Najran Industrial City, developed by MODON about 45 km north-east, and the region's mining complexes create some classified areas, though demand is smaller than in the Eastern Province. If you are specifying an Ex-proof smartphone for Najran, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Najran: projects and investment
Copper and zinc reserve zones covering another 70 square km are identified near Najran, pointing to possible future mining and processing work.
Najran: industry on the ground
Factories in the region cover food processing, chemicals, plastics, paper and non-metallic minerals, so hazards range from solvents to combustible dusts.
Najran: rules and approvals
Saudi Arabia's Communications, Space and Technology Commission issues radio type approval, renewed every two years, and accepts European test documents for handsets.
Najran: geography and layout
The city lies in the fertile Wadi Najran, a valley that has long been a crossroads of caravan routes, so industrial work sits close to farmland and water sources.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Najran. The sheet notes industrial plant dust areas classified Zone 21 as well as some gas areas. A marking check in Najran therefore needs to ask whether the hazard is gas or dust, because a gas-group marking such as the IS-04Z1 target II 2 G Ex ib IIC T4 does not cover dust.

Questions · Najran
Frequently asked questions
Can we buy an Ex-proof smartphone in Najran today?
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.
What does an Ex-proof smartphone in Najran 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Najran would use it?
Likely candidates are chemical and plastics manufacturing, mining and quarrying operations, stone and industrial 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.
Is demand for Zone 1 equipment large around Najran?
Smaller than in the Eastern Province. The area has factories making chemicals, plastics, paper and food products, plus quarrying and mining, so classified areas exist but are mainly in individual plants. Each factory or mine sets its own approval rules.
How does altitude and climate affect equipment at Najran?
The city is about 1,200 to 1,300 m above sea level and is a little cooler than Riyadh, but still hot desert. Handsets still need heat tolerance, and long supply lines mean spare batteries and chargers should be carried.
Does the IS-04Z1 cover dust areas such as Zone 21?
The target marking, II 2 G Ex ib IIC T4, refers to gas atmospheres. Dust areas such as Zone 21 call for dust-related protection, which is a different marking. Certification is still in progress, so do not assume dust suitability. Ask the supplier directly and confirm with the factory's safety officer.
