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. Buyers searching for an Ex-proof smartphone supplier for United Kingdom 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 Ex-proof smartphone for United Kingdom 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.
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.

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.
The classified areas, operators and sites below are the ones covered in 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.
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.
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.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In United Kingdom. A UK marking check reads II 2 G Ex ib IIC T4 and compares it with the zone on the permit. Zone 1 and Zone 2 areas at gas networks, water and waste sites are common inland, and the IS-04Z1 target covers Zone 21 dust as well. The gas group needed depends on the process on site.
There is no stock to order for United Kingdom yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.

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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
The market guide for United Kingdom covers Aberdeen, St Fergus, Sullom Voe, Grangemouth, 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.
Offshore installations typically add their own permit-to-work, helicopter-transport and zone rules on top of UK law, and operators often keep lists of approved portable devices. Ask the duty holder or contractor for its approved-equipment procedure before sending devices offshore.
Equipment for Great Britain can be placed on the market under UKCA, using SI 2016 No. 1107 and a UK approved body, or under CE. Manufacturers usually keep both routes open if they sell in the EU too. Confirm the current labelling and importer details requirements with a UK approved body.
The 50 MP camera with PDAF is designed to give photographs sharp enough to act on, and GNSS can record where each was taken. Whether they are accepted as permit evidence is a matter for your duty holder and permit-to-work procedure.
