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.

Intrinsically Safe Mobile Phone Supplier for IOCL
IndianOil is a government-owned Indian oil and gas company working across refining, pipelines and petroleum marketing. 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. Buyers searching for an intrinsically safe mobile phone supplier for IOCL can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.

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: 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: 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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In IOCL. Rounds across refinery process units, product pipeline terminals and loading gantries involve reading gauges, photographing equipment and filing permits, and shutdowns add large crews. A handheld designed as intrinsically safe could carry those tasks on one device. The IS-04Z1 is designed for this use, though certification is still in progress.
The route · supply
Sourcing the IS-04Z1 for IOCL
There is no stock to order for IOCL yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.

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 intrinsically safe 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
