United Kingdom: rules and approvals
Great Britain applies SI 2016 No. 1107, the UK version of the ATEX rules, so equipment for explosive atmospheres is assessed by UK approved bodies and carries UKCA marking and a body number.
The IS-04Z1 is an intrinsically safe Android smartphone designed for Zone 1 and Zone 21 work, from a North Sea deck to a gas governor kiosk at the end of a street. Historically most UK gas came from Morecambe Bay and the Southern North Sea off East Anglia and Lincolnshire, both now in decline, while oil comes mainly from the Central Graben of the North Sea. An explosion proof smartphone distributor in United Kingdom would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. United Kingdom has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in United Kingdom. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS United Kingdom market guide.
Great Britain applies SI 2016 No. 1107, the UK version of the ATEX rules, so equipment for explosive atmospheres is assessed by UK approved bodies and carries UKCA marking and a body number.
Around 39 billion barrels of oil equivalent have been extracted from the UK Continental Shelf over four decades, and Brent crude from the British North Sea remains a major international price benchmark.
The UK government has legislated to keep recognising CE marking alongside UKCA for a range of product regulations, so check whether the route applies to your product category.
UK crude oil and condensate production had fallen to about 630,000 barrels a day by 2024, so much of the current work is maintenance, life extension and decommissioning of mature installations.
“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 United Kingdom. Explosion-proof is the everyday phrase, but a UK installation holds very different areas, from offshore platforms to St Fergus and Sullom Voe, and gas networks inland. Flameproof Ex d suits fixed enclosures, while the IS-04Z1 uses intrinsic safety to limit the energy of a handheld, which suits permit-controlled entries.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for United Kingdom. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
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.

Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for United Kingdom.
DSEAR places duties on employers to classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment. A site will therefore expect devices used in classified areas to be suitable for the zone, gas group and temperature class stated in its area classification records.
Yes. Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so an ATEX-certified product can be sold there without UKCA, although a UKCA route with a UK approved body also exists. Northern Ireland still requires CE. Check the current rules before shipping.
It combines 4G LTE, Wi-Fi and four-constellation GNSS to hold a position and a connection where one network is not enough. Actual coverage depends on the site, so test the unit on your own route before relying on it.
