10th of Ramadan City
About 46 km from Cairo, it is reported to host 5,083 factories and around 353,656 jobs across electronics, food, pharmaceuticals, plastics, steel and other sectors.
The Cairo Metro opened in 1987, is the oldest metro system in Africa and has over 1 billion passenger rides a year, so underground and railway systems are a major source of civil and electrical work. 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 IECEx smartphone for Greater Cairo, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Cairo. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
About 46 km from Cairo, it is reported to host 5,083 factories and around 353,656 jobs across electronics, food, pharmaceuticals, plastics, steel and other sectors.
The refinery northeast of Cairo came onstream in 1973 and has a reported capacity of about 161,000 barrels per day.
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.
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.
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.
Natural gas made up 84% of Egypt's electricity mix in 2023, and Egypt produced 45% of Africa's gas-fired electricity in 2022, so gas-fired power stations and gas networks are the backbone of the national grid.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Greater Cairo. The Mostorod refinery is run by the Cairo Oil Refining Company under EGPC, while Helwan Cement belongs to Heidelberg Materials Egypt, an international group. IECEx documentation, including a certificate of conformity and schedule of conditions, is a familiar reference there. The IS-04Z1 is designed for the route; nothing is issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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.
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.
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.
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.
