Bacton
Bacton is a complex of six gas terminals operated by Shell, Eni, Perenco and National Grid, plus the Interconnector and BBL terminals linking to continental Europe.
Norwich is a cathedral city and service centre for East Anglia, not a heavy-industry site. Nearby hazardous-area work centres on the Bacton gas terminal complex on the north Norfolk coast, which receives North Sea gas, and the offshore energy port at Great Yarmouth. If you are specifying an ATEX and IECEx smartphone for Norwich and the Norfolk coast, 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 Norwich and the Norfolk coast: 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. 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 |
|---|---|---|
| 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 | Norwich and the Norfolk coast: Gas terminal process areas, Gas receipt and blending, Interconnector terminals | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Norwich. 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.
Bacton is a complex of six gas terminals operated by Shell, Eni, Perenco and National Grid, plus the Interconnector and BBL terminals linking to continental Europe.
Three of the terminals receive gas from Southern North Sea and some Central North Sea fields, including Leman, Hewett and Cygnus.
Norwich is the county town of Norfolk, lying on the River Wensum about 100 miles north-east of London and 65 miles east of Peterborough, and is the largest settlement in East Anglia.
Regional industry bodies have described the offshore wind supply chain in East Anglia as a growing cluster, with ScottishPower Renewables and Vattenfall wind farms off the coast driving demand for coastal contractors.
Norwich Airport is home to major offshore energy helicopter transport operations alongside corporate and general aviation and the East Anglian Air Ambulance, and KLM Engineering runs six maintenance bays across three hangars there.
The Norwich City Council area had an estimated population of about 144,000, so engineers and technicians are drawn from a sizeable local labour pool as well as from the wider county.
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 Norwich and the Norfolk coast. A reviewer at Bacton would expect certificate evidence matched to each terminal operator's DSEAR assessment, and the interconnector terminals linking to continental Europe bring contractors used to international documentation. That is why a dual ATEX and IECEx route is designed. Both remain in progress for SAMS, and nothing has been issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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 gas terminal process areas, gas receipt and blending, interconnector terminals, offshore support port facilities. 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.
In Great Britain, equipment for explosive atmospheres is normally supplied under UK regulations with UKCA marking, and CE-marked ATEX equipment has been widely accepted under transitional rules. Check the current position with the site operator and certification body before ordering handheld devices.
Great Yarmouth is about 20 miles east, so road transfers of equipment and engineers are short, but offshore access depends on vessel and helicopter schedules and weather. Plan equipment delivery and testing onshore at the port base ahead of crew changes, and confirm timings with the operator.
No. It is a cathedral city and service centre for East Anglia. Nearby hazardous-area work centres on the Bacton gas terminal complex on the north Norfolk coast and the offshore energy port at Great Yarmouth. Confirm requirements with the site operator for the specific terminal.
