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.

WhereONGC
Short answer. An explosion proof mobile phone for ONGC cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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.

More about ONGC that matters for portable equipment
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.
ONGC: projects and investment
A 2015 offshore contract for the Bassein development project and a 2016 plan to invest in Tripura gas wells and surface facilities show continuing offshore and north-eastern activity.
ONGC: industry on the ground
ONGC accounts for around 70% of India's domestic crude oil and around 84% of its natural gas, so a large share of the country's upstream hazardous-area work sits with this one operator.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In ONGC. On ONGC platforms and onshore fields people say explosion-proof loosely, but the real protection concepts differ. Flameproof Ex d contains an internal ignition inside a strong housing, while intrinsic safety limits electrical energy so ignition cannot occur. A phone used on Mumbai High decks or in Cambay production areas is normally an intrinsic safety question, and the IS-04Z1 is designed around that concept.
The route · supply
Sourcing the IS-04Z1 for ONGC
Supply of the IS-04Z1 to ONGC starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 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
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · ONGC
Frequently asked questions
Can ONGC buy the IS-04Z1 today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an explosion proof 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
