Dense urban setting
The refineries sit in the Mahul-Chembur area within the metropolitan region, which Wikipedia notes is surrounded by a number of chemical plants, so site access and security controls are normally strict.

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 Mumbai, Maharashtra. Mumbai's refineries sit in a dense urban area, so security teams and corporate HSE departments both review what enters site. A dual ATEX and IECEx route helps international contractors who work on BPCL and HPCL projects. The IS-04Z1 has no certificate yet, and both routes are in progress.

Questions · Mumbai India
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Mumbai India today?
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.
What does an ATEX and IECEx smartphone in Mumbai India cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 Mumbai, Maharashtra would use it?
Likely candidates are refinery process units, petroleum storage terminals, marine oil handling, chemical plants. 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 do I ship equipment to Mumbai?
Jawaharlal Nehru Port is the main container port for the region, with 30 container freight stations and links to inland depots. Use an experienced freight forwarder and confirm customs documents in advance.
How does the Mumbai monsoon affect equipment and logistics?
Rain is heavy from June to September, peaking in July, and monsoon floods can disrupt roads and ports. Plan deliveries and site visits outside the peak monsoon where possible, and transport devices in waterproof cases.
What should be planned for the monsoon at Mumbai sites?
Intense rain from June to September makes water and corrosion protection important for outdoor work. A sealed IP68 design helps, but users should still check seals and dry the device. Ask the operator how outdoor handheld use is managed during heavy rain.
