India: rules and approvals
Telecom approvals involve TEC's MTCTE scheme, WPC Equipment Type Approval for radio equipment, BIS registration for electronics, and trusted-source designation for equipment connected to licensed networks.
The IS-04Z1 is designed for people who work inside classified areas at Indian refineries, gas plants, LNG jetties and API blocks: field operators, inspection engineers, shift in-charges, and the HSE and materials teams whose sign-off a device has to survive. Buyers searching for an explosion proof smartphone supplier for India can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An explosion proof smartphone for India cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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 |
|---|---|---|
| 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 | India: Mumbai and the offshore basin, Panipat and Mathura, Jamnagar, Gujarat | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS India market guide covers.
Telecom approvals involve TEC's MTCTE scheme, WPC Equipment Type Approval for radio equipment, BIS registration for electronics, and trusted-source designation for equipment connected to licensed networks.
The Jamnagar refinery in Gujarat, commissioned in July 1999, now has installed capacity of 1.24 million barrels a day, the most at any single location in the world.
A July 2025 PESO procedure accepts an IECEx certificate with test report for all manufacturers, and EU-type examination certificates only from EU-based manufacturers.
PESO approval from the Chief Controller of Explosives is required for Ex electrical apparatus at petroleum, gas cylinder and pressure vessel premises, under rules such as the Petroleum Rules 2002.
“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 India. Explosion-proof and flameproof are used loosely in India, but the real choice is between concepts: flameproof Ex d for enclosures and intrinsic safety for a handset moved around plant. At refineries, gas plants and LNG jetties the IS-04Z1 is designed around intrinsic safety rather than a heavy flameproof housing.
Nothing can be bought for India today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you at launch.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
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.
The market guide for India covers Jamnagar, Gujarat, Dahej and the Gujarat PCPIR, Hazira and Surat, Vadodara, Koyali, Ankleshwar, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Supplier guides list TEC's MTCTE scheme, WPC Equipment Type Approval for radio equipment, BIS registration and trusted-source designation for network equipment, each with its own scope. Which ones apply depends on the device, so check current requirements with the Department of Telecommunications or an agent.
A July 2025 procedure accepts an IECEx certificate of conformity with its test report from all manufacturers, and EU-type examination certificates from EU-based manufacturers only. Edition lists and document requirements change, so check the current PESO notice or ask a consultant before applying.
The IS-04Z1 has IP68 sealing, which helps with water and dust. That is an ingress rating only, and battery behaviour in heat and humidity is worth testing. Ask for the datasheet's operating ranges and trial a unit on a coastal site round.
