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.

Supplier approval · IOCL
Becoming an approved supplier to 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.

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.

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 smartphone for IOCL cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
How will SAMS supply IOCL?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Which Indian Oil sites typically need intrinsically safe phones?
Typical sites are refinery process units, tank farms, pipeline pumping stations, bulk terminals and loading gantries, plus retail forecourts and aviation fuel installations. Zone classification is site-specific, so ask the location's safety department for area drawings and its portable-electronics policy.
How do heat and monsoon affect devices in Indian refineries?
Plains and coastal refineries are hot and humid, with a heavy monsoon season that brings rain and condensation. For handheld devices check operating temperature range, ingress protection and corrosion resistance, and ask the site about its environmental limits.
How does a supplier join IndianOil's vendor list?
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 IS-04Z1 is not yet certified, so no approval can be claimed.
