LNG terminal
Petronet LNG reported the Dahej terminal expanded from 17.5 to 22.5 million tonnes a year, with the additional capacity commissioned by 31 March 2026. A third jetty for LNG, ethane and propane is being built.
Dahej is a cargo port and industrial area in Bharuch district on the Gulf of Khambhat, Gujarat. It hosts Petronet LNG's terminal and petrochemical and liquid-handling operations, so gas, LNG and chemical handling create Zone 1 areas. If you are specifying an ATEX and IECEx smartphone for Dahej, Gujarat, 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 Dahej, Gujarat: 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 |
|---|---|---|
| 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 |
| Where it applies | Dahej, Gujarat: LNG storage and regasification, Ethane and propane handling, Marine jetties | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Dahej 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.
Petronet LNG reported the Dahej terminal expanded from 17.5 to 22.5 million tonnes a year, with the additional capacity commissioned by 31 March 2026. A third jetty for LNG, ethane and propane is being built.
Dahej is a deep-water cargo port handling LNG, chemicals, coal and petroleum products, with a large Special Economic Zone in its hinterland and rail and road links.
The chemical port terminal can handle liquid cargo at up to 25,000 tonnes a day, and a bulk facility unloads up to 30,000 tonnes a day, so liquid and dust hazards both occur on the waterfront.
Tides at Dahej are large: high water can rise 10 to 11 metres, and vessels anchor about 5.5 kilometres from the old port, so marine work depends on tide tables.
Dahej has two LNG jetties, the first for Q-Flex vessels and the second for Q-Max carriers, and had handled 3,538 cargoes by 30 September 2024.
The surrounding Bharuch district has a tropical savanna climate, with average maxima of about 40 degrees Celsius in April and May and around 800 millimetres of monsoon rain by September.
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 Dahej, Gujarat. Dahej combines an LNG terminal, a chemical port and petrochemical plants, so a reviewer may meet evidence requests from different operators. Offering ATEX and IECEx routes helps international contractors who work across the terminal, jetties and chemical plants. The IS-04Z1 has no certificate yet, and both routes remain in progress.
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.
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 lng storage and regasification, ethane and propane handling, marine jetties, petrochemical plants. 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.
The nearest airports are Ahmedabad, Surat and Vadodara, with Bharuch about 45 kilometres from the port. Road transfer is the norm, and sites usually require advance gate passes and induction.
April and May are very hot, and the monsoon brings about 800 millimetres of rain between June and September. Choose water-resistant devices with a wide operating temperature range and check the datasheet.
New jetties, storage and process areas will carry their own classification once designed, and these may differ from existing ones. Treat each area on its own record. Confirm the zone, gas group and temperature class with the terminal operator for any new or modified area.
