Wikipedia records three seasons (winter, summer, monsoon) with 250 to 300 cm of rain a year, so handsets used outdoors need good ingress protection.

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 Vapi, Gujarat. The IECEx scheme matters in Vapi mainly where a plant supplies or is audited by international customers. The certificate of conformity and its schedule of conditions are the documents a reviewer would read. For the IS-04Z1 they are targets, not issued papers, so nothing should be specified on them yet.

Questions · Vapi India
Frequently asked questions
Can we buy an IECEx mobile phone in Vapi 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 Vapi 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 Vapi, Gujarat would use it?
Likely candidates are solvent storage and handling, chemical reactors and process areas, dye and pesticide manufacturing, effluent and tank areas. 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.
Why is Vapi's rainfall relevant for equipment?
Vapi gets 250 to 300 centimetres of rain a year, mostly in the monsoon season. Choose sealed, water-resistant devices with a suitable ingress rating, and keep spares and chargers in dry storage.
How do I reach Vapi?
Vapi is on National Highway 48 and the Mumbai-Ahmedabad railway, about 185 kilometres from Mumbai. Most visitors fly into Mumbai or Surat and continue by road.
Who decides whether a handset may enter a Vapi solvent or reactor area?
The plant owner decides, normally through its safety or maintenance manager, based on its own classification. The estate has many small units, so rules differ plant to plant. Ask each plant for its zone drawings and permit procedure before bringing any device on site.
