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 Jamnagar, Gujarat. A refinery of this size draws international engineering and licensor contractors working to project specifications. IECEx certificates of conformity and schedules of conditions are the shared language for many of them. The IS-04Z1 is being assessed on this route, and no certificate has been issued.

Questions · Jamnagar India
Frequently asked questions
Can we buy an IECEx mobile phone in Jamnagar India today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an IECEx mobile phone in Jamnagar 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.
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 Jamnagar, Gujarat would use it?
Likely candidates are refinery process units, petcoke gasification, refinery off-gas cracker and petrochemical units, crude and product tank farms. 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.
Is Vadinar part of Jamnagar?
Vadinar is a separate coastal town in Devbhumi Dwarka district with its own refinery and crude oil terminals, about 47 kilometres from Jamnagar airport. Many contractors serve both sites, but access arrangements are separate.
What is the Jamnagar climate like for equipment?
It is hot semi-arid, with a very hot and humid season from March to May and an irregular monsoon. Cyclones occasionally occur, so look for sealed devices with a suitable temperature range.
Does one approval cover the whole Jamnagar complex?
Not automatically. The complex has many unit types, and each area has its own classification and permit regime. A device may be acceptable in one and not in another. Confirm with Reliance's site safety team which areas an approved handheld may be used in.
