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 Yanbu Industrial City. Crude and product storage, loading and marine terminals normally involve fuels, while petrochemical plants may differ. A marking check at Yanbu should read zone, gas group and temperature class from each plant's own classification. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, still a target.

Questions · Yanbu
Frequently asked questions
Can we buy an Ex-proof smartphone in Yanbu 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 Yanbu cost?
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.
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 Yanbu Industrial City would use it?
Likely candidates are refinery process units, petrochemical plants, crude and product storage and loading, marine terminals. 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.
How is Yanbu connected to the east of the country?
The East-West crude pipeline of about 1,200 km can deliver up to 7 million barrels a day to Yanbu from the Eastern Province. Road and air links also exist, but heavy equipment normally arrives through the port; confirm routing and permits with the client.
Which part of Yanbu has the classified areas?
Mostly the industrial city in the south, with its refineries and petrochemical plants, and the port about 20 km south of Yanbu town. Yanbu Al-Bahr in the north is the main residential and commercial area, so offices and hotels are separate from the plants.
Does coastal exposure affect handset choice at Yanbu?
Yes. With a hot desert climate, a July record of 51 C and a Red Sea coast, sealed equipment is favoured. IP68 helps against dust and splash, but heat and salt exposure should be checked against the datasheet. Ingress protection does not replace the Ex marking needed for classified areas.
