ONGC: infrastructure
ONGC owns and operates over 11,000 km of pipelines and around 230 drilling and workover rigs, so field crews, rig sites and pipeline stations are the main places where portable equipment is used.

IECEx Mobile Phone for ONGC
In May 2023 ONGC said it would start oil production in the Krishna Godavari Basin by June, adding new deepwater activity on India's east coast. It operates onshore basins such as Assam, Cambay and the East Coast, the Mumbai High offshore field, and gas processing plants at Hazira and Uran. This page explains what to look for in an IECEx mobile phone for ONGC, and where the IS-04Z1 stands against that list today.

Supplier approval · ONGC
Supplier registration at ONGC
ONGC buyers register through its e-tender portal (user ID obtained via the new-bidder access authorisation link), and bidders need a digital signature certificate; confirm current rules with ONGC. 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 ONGC that matters for portable equipment
ONGC: who works there
In January 2018 ONGC completed the acquisition of a 51.11% stake in Hindustan Petroleum Corporation, so refining and fuel distribution sites are now linked to the ONGC group.
ONGC: who works there
ONGC Videsh, the international arm renamed in 1989, holds overseas oil and gas projects, so some ONGC contractors also work to foreign operators' rules.
ONGC: geography and layout
The headquarters is Deendayal Urja Bhawan on Nelson Mandela Road in Vasant Kunj, Delhi, while the working assets are in Assam, Gujarat, Mumbai offshore, the Cauvery and Krishna Godavari regions.
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 ONGC. ONGC is a national producer, yet its projects draw visiting contractors and engineering firms used to the international scheme. For them, IECEx evidence means a certificate of conformity together with its schedule of conditions, which records any special conditions of use. IECEx is a target for the IS-04Z1 and is in progress, so reviewers should treat it as a planned route, not a held approval.

Questions · ONGC
Frequently asked questions
Can ONGC buy the IS-04Z1 today?
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.
What does an IECEx mobile phone for ONGC cost?
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.
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.
How does ONGC approve suppliers?
ONGC buyers register through its e-tender portal (user ID obtained via the new-bidder access authorisation link), and bidders need a digital signature certificate; confirm current rules with ONGC.
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 monsoon and heat affect devices on Indian sites?
Western offshore and Gujarat sites are hot and humid, with a heavy monsoon season, while Assam is very humid and rainy. For handheld devices that means good sealing, corrosion resistance and thermal limits; ask the asset about its environmental requirements.
Where would intrinsically safe phones be used at ONGC?
Typical uses are offshore platforms off Mumbai, onshore well sites and group gathering stations in Assam and Gujarat, and the gas processing plants at Hazira and Uran. Classification is set per installation, so ask each asset's HSE team for area drawings and its rules on portable electronics.
Do I need to register with ONGC before offering a device?
ONGC buyers are reported to register through its e-tender portal, and bidders need a digital signature certificate. That process is separate from product certification. The IS-04Z1 has no certificate yet, so any approach should begin with the datasheet and a safe-area evaluation. Check current rules with ONGC procurement before bidding.
