Location and access
Ankleshwar is about 14 km from Bharuch city, on the Mumbai-Delhi national highway and the Western Railway line.
Ankleshwar, in Bharuch district, Gujarat, hosts a large GIDC industrial estate and chemical cluster of about 1,600 hectares. The Ankleshwar Industrial Association, part of the Gujarat Industrial Development Corporation estate, has over 2,000 industries registered, so a single estate holds a very large number of separate operators. If you are specifying an explosion proof mobile phone for Ankleshwar, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Ankleshwar: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Ankleshwar: Chemical reactors and solvent areas, Dye and dye intermediate plants, Pesticide manufacturing | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Ankleshwar India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Ankleshwar is about 14 km from Bharuch city, on the Mumbai-Delhi national highway and the Western Railway line.
The Gujarat Pollution Control Board regulates industrial pollution, which can add compliance requirements for plant operators.
Heavy monsoon rain often brings flooding to the Narmada basin, with major floods most recently in 2023, although the damming of the river has largely controlled it.
Ankleshwar is a hub of the Indian chemical industry, and its industrial estate produces more than 5 percent of the country's chemical output, including pharmaceuticals and dyes.
The nearby Dahej port has a dedicated liquid handling facility run by the Gujarat Chemical Port Terminal Company that can load or unload up to 25,000 tonnes a day.
Pollution in the estate is regulated by the Gujarat Pollution Control Board, which asks the industrial association to self-enforce among its member units.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Ankleshwar. In a chemical cluster, explosion-proof is a common term but covers different concepts. Flameproof Ex d suits fixed motors and lighting, while a handheld phone uses intrinsic safety. Reactors, dye intermediate plants, pesticide manufacturing and bulk drug solvent areas each need their own classification by the plant operator.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Likely candidates are chemical reactors and solvent areas, dye and dye intermediate plants, pesticide manufacturing, pharmaceutical bulk drug solvent handling. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Many telecom products now need mandatory testing and certification under the telecom authority's scheme, which started in 2019 and requires an authorised Indian representative. Confirm with your supplier whether the specific handset or radio is covered and what documents they hold.
Rain falls mainly from late June to September with around 800 millimetres a season, and April and May are very hot. Choose sealed, water-resistant devices with a suitable temperature range and check the datasheet figures before purchase.
A managed fleet is useful even for small plants, because it lets a supervisor control apps, updates and lost devices. The estate has many member units of varied size. EMM or MDM enrolment suits that. Confirm with each plant which areas are classified before deploying devices.
