Pollution oversight
The Gujarat Pollution Control Board regulates industrial pollution, which can add compliance requirements for plant operators.
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. Sources report between 1,500 and 2,000 units making chemicals, dyes, pesticides and pharmaceuticals, where solvent handling creates classified areas. If you are specifying an IECEx smartphone 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |
| 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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The Gujarat Pollution Control Board regulates industrial pollution, which can add compliance requirements for plant operators.
The Ankleshwar Industries Association lists 220 chemical, 156 dye and dye intermediate, 11 pesticide and 69 pharmaceutical member units, among others.
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.
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.
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 Ankleshwar. With between 1,500 and 2,000 units reported in the GIDC estate, many making products for export, buyers and auditors from abroad may be familiar with IECEx. A certificate of conformity with its schedule of conditions would be the reference. The IS-04Z1 is designed for the route; nothing is issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
