EU product rules
Under the Windsor Framework, relevant EU product rules apply in Northern Ireland, so equipment is typically CE marked, with UKNI added where a UK notified body is used.

IECEx Smartphone in Northern Ireland
Machinery and equipment manufacturing, food processing, textile and electronics manufacturing are the leading industries, concentrated mostly in the eastern parts of Northern Ireland around Belfast. Zone 1 work arises at power stations, gas transmission assets and fuel storage. This page explains what to look for in an IECEx smartphone for Northern Ireland, and where the IS-04Z1 stands against that list today.

WhereNorthern Ireland
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Northern Ireland: 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.

Ballylumford, owned by EP UK Investments since 2019, is the region's largest power station and runs on natural gas. Coolkeeragh near Derry is a 400 MW gas-fired plant owned by ESB.
Field notes · Northern Ireland
More about Northern Ireland that matters for portable equipment
Northern Ireland: industry on the ground
Northern Ireland was self-sufficient in food production by 2021 and exported more than half of its meat and crops, so food plants with dust, ammonia refrigeration and flour or feed handling are common.
Northern Ireland: infrastructure
Gas for Greater Belfast arrives through the 24-inch Scotland-Northern Ireland pipeline, and a north-west pipeline from Carrickfergus to Derry opened in November 2004, so gas networks and compressor sites sit across the east and north-west.
Northern Ireland: people and language
Unemployment was about 1.6% in early 2025, so qualified engineering and maintenance contractors can be hard to book at short notice during shutdown periods.
Northern Ireland: infrastructure
The electricity grid is operated by SONI and run by Northern Ireland Electricity, connected to the Republic by interconnectors of up to 1,200 MW and to Great Britain by the 500 MW Moyle interconnector.
The term · IECEx
What “IECEx” means for a smartphone
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 Northern Ireland. Power station and gas pipeline owners such as Mutual Energy and ESB operate across borders, so contractors and visiting specialists may bring IECEx documentation. The aim is a certificate of conformity and a schedule of conditions that can be read against a specific area. It is still in progress and cannot be relied upon yet.

Specifying an IECEx smartphone for Northern Ireland
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Northern Ireland
Frequently asked questions
Can we buy an IECEx smartphone in Northern Ireland today?
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.
What does an IECEx smartphone in Northern Ireland cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Northern Ireland would use it?
Likely candidates are gas-fired power station fuel systems, gas transmission pipeline assets, gas pressure reduction sites, fuel storage. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
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.
Is crossing the Irish Sea a logistics issue for equipment supply?
Goods moving between Great Britain and Northern Ireland pass through post-Brexit customs arrangements, which can add paperwork and lead time. For urgent site equipment, plan stock holding in Northern Ireland or the Republic and confirm the current import documentation with your freight forwarder.
How does the damp maritime climate affect phone selection?
Northern Ireland has a mild but wet and windy climate, with frequent rain and salt air near the coast, so sealing, corrosion resistance and condensation tolerance matter more than extreme temperature ratings. Check ingress protection and gasket quality, and ask the site about its own requirements.
Which marking applies to equipment in Northern Ireland?
Under the Windsor Framework, relevant EU product rules apply in Northern Ireland, so equipment is typically CE marked, with UKNI added where a UK notified body is used. Because rules can change, confirm the current position with the site operator and HSENI guidance.
