More about Ras Tanura that matters for portable equipment
Ras Tanura: background
The refinery was established in 1939 and expanded substantially after the Second World War, so equipment and layouts range from very old to recently modernised.
Ras Tanura: background
The area was officially called Rahima from 1941 until 1986, when the historical name was restored, so older Aramco documents and maps may use the earlier name.
Ras Tanura: who works there
The governorate's industrial infrastructure is centrally managed and operated by Saudi Aramco, so a single operator's rules cover refinery, terminal and gas plant work.
Ras Tanura: geography and layout
Ras Tanura is a peninsula governorate bordered by Jubail to the north and Qatif to the west and south, so road access runs through neighbouring governorates.
The term · IECEx
What “IECEx” means for a smartphone
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 Ras Tanura. A crude export terminal draws in tanker, marine and terminal contractors from many countries, so IECEx is a convenient shared reference. A certificate of conformity and schedule of conditions would be the documents reviewed. For the IS-04Z1 they remain targets, as certification is in progress.

- 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.

Questions · Ras Tanura
Frequently asked questions
Can we buy an IECEx smartphone in Ras Tanura 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 IECEx smartphone in Ras Tanura 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Ras Tanura would use it?
Likely candidates are refinery process units, crude export terminal piers and sea islands, storage tank farms, natural gas liquids fractionation (ju'aymah). 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.
Who sets equipment rules at Ras Tanura?
Saudi Aramco manages and operates the industrial infrastructure, so its safety and approval procedures apply to contractors working on the refinery, terminal and gas plant. Check the current vendor and equipment-approval requirements with the Aramco project owner or the main contractor.
Are Ras Tanura facilities old or new?
Both. The refinery dates from 1939 and has been expanded many times, so older plant sits alongside modern units. For handheld devices, ask for the area classification and equipment group for each unit, since gas groups and temperature classes can differ between old and new areas.
Can a handset be used on the piers and sea islands?
Only if its protection suits the classified area there, and if the operator permits it. The piers and sea islands handle crude, where Aramco classifies the area. Ask Aramco or the site contractor for the zone and the device approval route before any handset goes near a loading point.
