Inland site
Mathura is inland and is supplied with crude through the Salaya-Mathura pipeline, a 2,663 km line from the Gujarat coast, so there is no marine terminal.
Mathura in Uttar Pradesh is home to Indian Oil's inland refinery, commissioned on 19 January 1982 and now processing 8 million tonnes of crude a year. Process units and product storage define its Zone 1 areas. This page explains what to look for in an ATEX and IECEx mobile phone for Mathura, Uttar Pradesh, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Mathura, Uttar Pradesh: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Mathura India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
Mathura is inland and is supplied with crude through the Salaya-Mathura pipeline, a 2,663 km line from the Gujarat coast, so there is no marine terminal.
The refinery processes low-sulphur Bombay High and Nigerian crudes and high-sulphur Middle East crude, and supplies BS VI fuels to the Delhi NCR region.
Crude arrives through the Salaya-Mathura pipeline, which also supplies the Panipat and Baroda refineries, so feedstock supply is a shared pipeline network.
It was designed for 6.0 million tonnes a year, expanded to 7.5 million tonnes in 1989 and now processes about 8.0 million tonnes annually.
The refinery is located about 50 kilometres from the Taj Mahal, in the Agra-Mathura part of Uttar Pradesh.
The refinery began producing BS VI standard fuels for Delhi NCR ahead of the April 2020 mandate, showing continuing upgrade work.
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 Mathura, Uttar Pradesh. The inland refinery at Mathura is run by one operator whose HSE and procurement teams set clear requirements, while pipeline and shutdown contractors may bring international expectations. A dual ATEX and IECEx route addresses both. The IS-04Z1 has no certificate yet, and both certification routes are in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are refinery process units, crude and product tank farms, product loading gantries, pipeline pumping stations. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Mathura has a hot semi-arid climate with very hot summers, so check the device's maximum operating and charging temperature on the datasheet and avoid leaving it in direct sun or vehicles.
Process units, tank farms, pump areas and loading gantries have classified areas for flammable gas and vapour. The operator defines these and specifies approved equipment, so request the area classification before entering.
Heat can shorten battery life and dust can work into ports and seals. A sealed IP68 housing helps with dust. Keep devices out of direct sun between uses, and ask the operator about charging and storage arrangements for portable equipment during the hot months.
