IOCL: climate and equipment wear
Retail outlets range from city forecourts to Kaza in Himachal Pradesh, at 3,740 m the world's highest outlet under the company, so equipment may face mountain cold as well as coastal heat.

Supplier approval · IOCL
Supplier registration at IOCL
IndianOil runs an online vendor registration and empanelment portal, by goods, services or works category, and tenders are submitted electronically with a Class III digital signature certificate; confirm current rules on the IndianOil website. 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.
Field notes · IOCL
More about IOCL that matters for portable equipment
IOCL: rules and approvals
Indian Oil is under the administrative control of the Ministry of Petroleum and Natural Gas and has about 51% government ownership, so procurement follows public sector tendering norms.
IOCL: industry on the ground
The Indian Oil Group owns and operates 11 of India's 23 refineries, with a combined refining capacity of 80.7 million tonnes a year, so refinery shutdown and turnaround work is frequent and large.
IOCL: geography and layout
Indian Oil Corporation is registered in Mumbai and headquartered in New Delhi, while its refineries, pipelines and terminals are spread across the country, so site contacts are normally local rather than at head office.
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 IOCL. An IndianOil reviewer assessing a handset for Panipat, Mathura, Koyali, Haldia, Paradip or Barauni would expect a certificate of conformity, schedule of conditions and marking. ATEX and IECEx evidence helps international licensors, contractors and EPCs working on its refineries. The IS-04Z1 certification is in progress and nothing has been issued.

Specifying an ATEX and IECEx mobile phone for IOCL
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 · IOCL
Frequently asked questions
Can IOCL 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 ATEX and IECEx mobile phone for IOCL 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 IOCL approve suppliers?
IndianOil runs an online vendor registration and empanelment portal, by goods, services or works category, and tenders are submitted electronically with a Class III digital signature certificate; confirm current rules on the IndianOil website.
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 does supplier registration work at Indian Oil?
As a public sector company, Indian Oil buys through formal tendering and vendor registration, often via its e-procurement portal, and divisions may set their own technical requirements. Confirm the current registration process and required certificates with the relevant division's procurement office before bidding.
What standards apply to Ex equipment in India?
India applies Indian standards based on IEC explosive-atmosphere standards, and oil and gas sites are overseen by the petroleum and explosives safety authorities. Certification is normally through recognised Indian test bodies, so confirm which certificate Indian Oil's site will accept.
Do monsoon and heat affect a handset at Haldia or Panipat?
Yes. Panipat sees dust and high summer heat, while Haldia and Paradip face humidity and monsoon rain. Check the device's operating temperature range and battery plan. IP68 helps with water and dust but is not explosion protection. The IS-04Z1 is in certification. Confirm with IndianOil's HSE team.
