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.

More about IOCL that matters for portable equipment
IOCL: people and language
As of 31 March 2024 the company had 30,321 regular employees, of whom 18,570 were executives, and attrition was reported at around 1.5%, indicating a stable, long-serving workforce.
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.
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.
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.

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?
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.
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.
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.
