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.

Supplier approval · ONGC
How suppliers reach 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.

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.
The route · supply
Sourcing the IS-04Z1 for ONGC

- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04

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?
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.
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.
How will SAMS supply ONGC?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Which standards apply to Ex equipment on Indian oil and gas sites?
India generally relies on Indian standards aligned with IEC explosive-atmosphere standards, with certification commonly through recognised Indian test bodies and regulation by the petroleum and explosives safety authorities. Confirm with ONGC and the certifying body which certificate it will accept before supply.
Does ONGC have a single supplier registration process?
ONGC runs its own procurement through vendor registration and tendering, and individual assets or contractors may buy equipment too. There is no public approved list for hazardous-area devices, so confirm current registration and certification requirements with the relevant ONGC procurement office.
Will a handset cope with Mumbai High offshore conditions?
Offshore decks mean salt spray and damp air. IP68 protects against dust and immersion but not against ignition; the Ex marking, still in progress, governs hazardous use. Ask the platform HSE team how handheld devices are controlled on deck, and test battery behaviour in local heat before any fleet purchase.
