IOCL: infrastructure
Indian Oil accounts for about 35% of national refining capacity together with subsidiary Chennai Petroleum, and about 71% of downstream pipeline throughput capacity, giving it a very large pipeline and terminal network.

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: 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.
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.
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 IOCL. In IndianOil refineries and terminals, 'explosion-proof' is everyday shorthand for several concepts. Flameproof Ex d protects fixed motors and switchgear, while intrinsic safety limits the energy of a portable device. A phone carried on refinery or pipeline terminal rounds is a handheld, so the IS-04Z1 is designed around intrinsic safety.

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 explosion proof smartphone 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 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 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.
