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.

IECEx Mobile Phone for IOCL
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. It operates 11 of India's 23 refineries and a cross-country pipeline network of over 13,000 km. This page explains what to look for in an IECEx mobile phone for IOCL, and where the IS-04Z1 stands against that list today.

Supplier approval · IOCL
How suppliers reach 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: 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.
IOCL: logistics and access
Aviation fuel is supplied at major airports, and the company has subsidiaries such as Lanka IOC in Sri Lanka, so airport fuel farms and hydrant systems are also hazardous-area workplaces.
IOCL: who works there
Its interests cover refining, pipelines, marketing, exploration and production, natural gas and petrochemicals, and it is organised in seven major business divisions, so the buyer depends on which division owns the site.
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 IOCL. IndianOil runs a large refinery network, and international licensors and EPCs working on its projects often use IECEx documents. A certificate of conformity with its schedule of conditions gives IndianOil reviewers and these contractors a shared reference. The IS-04Z1 is designed for IECEx, still in progress. Indian requirements may apply separately.

Specifying an IECEx mobile phone for IOCL
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.

- 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

Questions · IOCL
Frequently asked questions
Can IOCL 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 IECEx mobile phone for IOCL 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 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.
