ATEX and IECEx Smartphone in Cairo
Cairo is a city rather than a single industrial site; the hazardous-area sites are in its surroundings. They include the Cairo Oil Refining Company's Mostorod refinery in Qalyubia, Helwan Cement to the south, and the large industrial zone of 10th of Ramadan City. If you are specifying an ATEX and IECEx smartphone for Greater Cairo, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Greater Cairo: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Greater Cairo
More about Greater Cairo that matters for portable equipment
Greater Cairo: people and language
Many international businesses and organisations have regional offices in Cairo, including the Arab League headquarters, so engineering and procurement teams are often briefed from the capital.
Greater Cairo: logistics and access
Like many megacities, Cairo suffers from high levels of pollution and traffic, so deliveries and site visits need extra time, and equipment should be dust-sealed against urban air.
Greater Cairo: logistics and access
Cairo International Airport in Heliopolis, about 15 km from the business district, covers roughly 37 square kilometres and is the busiest airport in Egypt, which helps urgent spares and visiting engineers reach the capital.
Greater Cairo: industry on the ground
Helwan, in southern Cairo, is the city's largest industrial centre, with iron and steel, cement and vehicle factories that developed into a major steelworks zone during the 1960s.
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 Greater Cairo. Cairo is a city rather than a single site, so a reviewer would ask which facility the device is for: the Mostorod refinery, Helwan Cement or a factory in 10th of Ramadan City. Each would expect its own certificate evidence. A dual route helps firms serving several of them. The IS-04Z1 holds no certificate today.
The route · specification
Specifying an ATEX and IECEx smartphone for Cairo
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 · Cairo
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Cairo today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an ATEX and IECEx smartphone in Cairo cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 Greater Cairo would use it?
Likely candidates are refinery process units, fuel storage, cement kiln fuel areas, factory solvent and gas areas. 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 Cairo's dust and heat matter when choosing Ex phones?
Yes, Cairo is hot in summer, dusty and polluted, so check the dust ingress rating, the maximum ambient temperature on the certificate and the sealing of ports and charging contacts. Regular cleaning of connectors and spare batteries are practical for long outdoor shifts.
How should I plan deliveries to Cairo for a project elsewhere in Egypt?
Equipment typically arrives through Cairo airport or Egyptian ports and is cleared through customs before onward road or rail transport. Allow for traffic and customs time, check radio-equipment import rules and confirm who receives and stores devices at the site.
Can one approach cover refinery and cement sites?
Not necessarily. A refinery has hydrocarbon process units and storage, a cement plant has kiln fuel areas, and factories may have solvent or gas areas. Each operator sets its own classification and approval route. Request zone and gas group data from each site before assuming one device suits all.
