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.

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 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.

Questions · Mathura India
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Mathura India 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 ATEX and IECEx smartphone in Mathura India 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.
Which areas at Mathura, Uttar Pradesh would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
How hot does Mathura get for handsets?
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.
What hazardous areas are at a refinery like Mathura?
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.
How does hot, dusty summer weather affect handhelds at Mathura?
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.
