Petronas: background
The first oil well in Malaysia was drilled at Miri in Sarawak in 1910, known as the Grand Old Lady, which shows a long industrial history in north Borneo and ageing facilities in places.

WherePetronas
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Petronas: 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Supplier approval · Petronas
How suppliers reach Petronas
Suppliers apply for a PETRONAS licence or registration through the PETRONAS Licensing Management System (PLMS), then trade through its procurement platforms such as the Unified Procurement Platform and B2B Marketplace. A licence covers upstream and downstream supply; a registration covers downstream subsidiaries only. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

More about Petronas that matters for portable equipment
Petronas: logistics and access
Petronas made its first crude shipment, 358,000 barrels to Japan, on 1 September 1975, and its lubricants subsidiary now operates in over 100 markets, indicating strong export and marine logistics.
Petronas: who works there
Petronas Carigali, formed in 1978, is the principal exploration and production subsidiary, with Petronas Dagangan and Petronas Chemicals handling marketing and petrochemicals, so each business unit runs its own sites.
Petronas: background
Petronas was established and incorporated on 17 August 1974 under the Petroleum Development Act, and is vested with all oil and gas resources in Malaysia, so it is the licensor as well as an operator.
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 Petronas. A PETRONAS reviewer would expect certificate evidence before a handheld enters an offshore platform, LNG plant or refinery unit. Its sites involve international contractors, EPCs and licensors, so a dual ATEX and IECEx route lets one product answer both families of paperwork. The IS-04Z1 is in certification and no certificate has been issued.

Questions · Petronas
Frequently asked questions
Can Petronas buy the IS-04Z1 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 mobile phone for Petronas cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined 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.
How does Petronas approve suppliers?
Suppliers apply for a PETRONAS licence or registration through the PETRONAS Licensing Management System (PLMS), then trade through its procurement platforms such as the Unified Procurement Platform and B2B Marketplace. A licence covers upstream and downstream supply; a registration covers downstream subsidiaries only.
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.
How do suppliers register with Petronas?
Petronas runs a vendor registration and licensing process for suppliers and contractors, and its business units apply their own technical assessment. Details change, so confirm the current registration route and product categories directly with Petronas procurement before offering equipment.
Which Petronas sites typically need intrinsically safe phones?
Typical Zone 1 and Zone 2 sites include offshore platforms, gas processing and LNG facilities such as Bintulu, refineries, petrochemical plants and fuel terminals. Classification is site-specific, so ask the operating unit's HSE team for area classification drawings and its rules for portable electronics.
Does a supplier need a PETRONAS licence to sell a handheld device?
PETRONAS says suppliers apply for a licence or registration through its licensing system. A licence covers upstream and downstream supply, while a registration covers downstream subsidiaries only. Check current requirements with PETRONAS. SAMS has appointed no distributor, and the IS-04Z1 has no certificate yet.
