The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Mathura, Uttar Pradesh. Mathura's refinery uses specialist contractors for shutdowns, many familiar with international documents. An IECEx certificate of conformity with its schedule of conditions is a reference they compare across projects. SAMS is pursuing IECEx for the IS-04Z1, and nothing has been issued.

Questions · Mathura India
Frequently asked questions
Can we buy an 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 IECEx smartphone in Mathura India 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
