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: 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 · 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 ONGC. An ONGC procurement or HSE reviewer would expect certificate evidence before any handheld goes onto an offshore platform or into a gas processing plant such as Hazira or Uran. A dual ATEX and IECEx route also suits international contractors and EPCs bidding for work on Mumbai High, Assam or Cambay. No certificate has yet been issued for the IS-04Z1; certification is in progress.
The route · specification
Specifying an ATEX and IECEx mobile phone for ONGC
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · ONGC
Frequently asked questions
Can ONGC 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 ONGC 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 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.
