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.
In 1978 Petronas set up the Malaysia LNG joint venture with Mitsubishi and Shell, taking 65% equity, which led to the large LNG complex in Bintulu, Sarawak, with its cryogenic and gas hazards. Its Malaysian sites include the Kertih petrochemical complex, Bintulu LNG, Melaka refining and the Pengerang integrated complex. If you are specifying an IECEx smartphone for Petronas, 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 Petronas: 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. An operator's own vendor approval is a separate step. 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 |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Malaysia. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
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.
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 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 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 headquarters is in Tower 1 of the Petronas Twin Towers in Kuala Lumpur, while operating assets are offshore and in Sarawak, Sabah and the east coast of Peninsular Malaysia.
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 Petronas. PETRONAS runs LNG, refining and petrochemical sites with international contractors and technology providers, many of whom work from IECEx documents. Reviewers would look for a certificate of conformity and its schedule of conditions. IECEx is a target for the IS-04Z1 and remains in progress, so treat it as a planned route, not a held approval.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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.
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.
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.
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.
