Large chemical cluster
The Ankleshwar Industries Association lists 220 chemical, 156 dye and dye intermediate, 11 pesticide and 69 pharmaceutical member units, among others.
Ankleshwar, in Bharuch district, Gujarat, hosts a large GIDC industrial estate and chemical cluster of about 1,600 hectares. Sources report between 1,500 and 2,000 units making chemicals, dyes, pesticides and pharmaceuticals, where solvent handling creates classified areas. This page explains what to look for in an ATEX and IECEx mobile phone for Ankleshwar, and where the IS-04Z1 stands against that list today.
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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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 |

| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |

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.
The Ankleshwar Industries Association lists 220 chemical, 156 dye and dye intermediate, 11 pesticide and 69 pharmaceutical member units, among others.
Ankleshwar is about 14 km from Bharuch city, on the Mumbai-Delhi national highway and the Western Railway line.
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.
Since 2019 India's telecom authority has rolled out mandatory testing and certification of telecom equipment, and the registration must be handled by an authorised Indian representative.
A bridge built in 1881, the Golden Bridge, still connects Ankleshwar and Bharuch across the Narmada, and a newer bridge carries the highway, so river crossings are well established.
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 Ankleshwar. A reviewer at an Ankleshwar chemical unit would expect certificate evidence matched to solvent handling, reactors and bulk drug areas. A dual ATEX and IECEx route helps firms that export to or work with international customers. The IS-04Z1 has no certificate issued, and certification is in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
