Supply and climate
Crude arrives by pipeline from the Gujarat coast. Summers are generally hot and dusty, with cold foggy winters.
Paraxylene and purified terephthalic acid units were commissioned in June 2006, and a naphtha cracker complex next door makes ethylene and propylene for polymers. Process units, a naphtha cracker and tank farms create Zone 1 areas. This page explains what to look for in an IECEx mobile phone for Panipat, Haryana, 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 Panipat, Haryana: 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. 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 |
|---|---|---|
| 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 | Panipat, Haryana: Refinery process units, Naphtha cracker and petrochemical units, Product tank farms | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Panipat 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.
Crude arrives by pipeline from the Gujarat coast. Summers are generally hot and dusty, with cold foggy winters.
Alongside the refinery, Indian Oil runs a naphtha cracker and PX-PTA units producing ethylene, propylene, paraxylene and purified terephthalic acid.
The city is also known as the city of weavers and a textile centre, with wool and cotton milling, glass and electrical appliance manufacturing.
The refinery produces ultra-low sulphur diesel under BS VI norms and has four ambient air monitoring stations that predate its start-up.
Panipat is 95 kilometres north of Delhi and 169 kilometres south of Chandigarh on NH-44.
A diesel hydrodesulphurisation unit was commissioned in 1999 to produce low-sulphur diesel.
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 Panipat, Haryana. Expansion work at Panipat brings project contractors, some international, who work to project specifications. An IECEx certificate of conformity with its schedule of conditions is a reference they commonly compare. SAMS is pursuing IECEx for the IS-04Z1, and nothing has been issued.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are refinery process units, naphtha cracker and petrochemical units, product tank farms, loading gantries. 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 refinery has process units, hydrogen and cracker areas, tank farms and loading facilities, and the naphtha cracker complex adds ethylene and propylene handling. The operator defines classified areas, so request the drawings before visiting.
Yes, the refinery has paraxylene and PTA units and a naphtha cracker complex alongside it. The units may have different operators and rules, so ask each site.
Cold can reduce battery capacity and fog adds moisture, so sealing and warm storage between uses help. An IP68 housing handles moisture ingress. Ask the operator about its rules for portable equipment outdoors in winter and where devices may be kept warm.
