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 Muscat. For a refinery unit, crude and fuel storage or a factory using solvents or gases, a marking check reads zone, gas group and temperature class on the label and compares each with the operator's classification. Solvents and fuels span several gas groups, so the target marking II 2 G Ex ib IIC T4 is compared with site records.

Specifying an Ex-proof mobile phone for Muscat
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 · Muscat
Frequently asked questions
Can we buy an Ex-proof mobile phone in Muscat 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 mobile phone in Muscat 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 Muscat would use it?
Likely candidates are refinery process units, crude export and fuel storage, industrial city factories using solvents or gases. 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 weather affect site operations?
Muscat is hot and arid, with most rain between December and April, and tropical cyclones such as Gonu in 2007 and Phet in 2010 have affected the coast in June. Plan for heat and storm disruption.
Do phones need local approval?
Yes. Oman's TRA type approval is required for telecom equipment, valid for four years, with a local representative and compliance mark. Confirm the current rules for each model with your supplier.
Is coastal heat a concern at Mina Al Fahal?
Summers are hot and humid along the coast, which affects outdoor equipment and battery life. Check the certified ambient range, avoid direct sun on parked devices and charge only in a safe area. Ask the operator for its device handling rules.
