Ras Tanura: rules and approvals
Saudi Arabia's Communications, Space and Technology Commission handles radio type approval; certificates are renewed every two years, with European test documents accepted.
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: logistics and access
The marine complex is described as handling over 2,000 tankers a year, using an artificial island, north and south piers and the Ju'aymah crude terminal.
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 Ras Tanura. Ras Tanura reviewers from Aramco would expect certificate evidence that suits the refinery, terminal and fractionation areas. A dual ATEX and IECEx route helps international contractors and marine specialists who work across terminals in several countries. The IS-04Z1 has no certificate yet; certification is in progress.

Questions · Ras Tanura
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone 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 ATEX and IECEx mobile phone 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.
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 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.
