Procurement base
Aramco's Dhahran office is responsible for registering companies located in Saudi Arabia, and also those in the UAE, Bahrain, Kuwait, Oman, Qatar, Iraq, Jordan, Syria, Egypt and Lebanon.
Dhahran Techno Valley hosts more than 20 multinational research centres and 65 deep-tech start-ups beside KFUPM, so pilot trials of new field equipment can be run close to the energy companies. It is an administrative and engineering centre; the classified areas it serves are at oil and gas facilities elsewhere in the Eastern Province. If you are specifying an Ex-proof smartphone for Dhahran, 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 Dhahran: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Dhahran: Oil and gas facilities served from Dhahran, Fuel storage and handling | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Dhahran. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Aramco's Dhahran office is responsible for registering companies located in Saudi Arabia, and also those in the UAE, Bahrain, Kuwait, Oman, Qatar, Iraq, Jordan, Syria, Egypt and Lebanon.
Aramco's headquarters and the King Fahd University of Petroleum and Minerals are here, so engineering and procurement decisions are concentrated in the city.
Aramco's headquarters has been in Dhahran for around 90 years, following a 1933 concession agreement and the first commercial oil output in 1938.
KFUPM supplies a talent base of more than 13,000 students and 800 researchers and professors, which supports a deep local pool of petroleum and engineering graduates.
A large part of the city is gated, including Aramco's headquarters and residential camp, King Fahd University of Petroleum and Minerals and the King Abdulaziz Air Base, so entry rules differ by compound.
Bahrain is about 32 km east of Khobar across the King Fahd Causeway, so teams working in both countries can base themselves in the Dammam area.
“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 Dhahran. A marking check done at headquarters should be framed by the destination site: the zone, gas group and temperature class are read from the facility's classification, not from Dhahran. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, which remains a target until certification is complete.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
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.
Likely candidates are oil and gas facilities served from dhahran, fuel storage and handling. 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.
Generally no. Much of Dhahran is gated, including the Aramco headquarters, residential camp, the university and the air base. Access is controlled by each compound, so arrange a host, a visitor pass and any required induction through your client before travelling.
Dhahran Techno Valley, next to KFUPM, hosts research centres and start-ups and pilots technology alongside large energy companies. Whether a particular trial is possible depends on the host organisation and its safety approvals, so contact them directly.
Not for ordinary office work, since Dhahran is mainly an administrative centre. The need arises when staff visit oil and gas facilities elsewhere in the Eastern Province, or handle fuel storage. Check the area classification for the place the device will be used, not for the city where it is bought.
