United Kingdom: industry on the ground
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.
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. This page explains what to look for in a rugged cell phone for United Kingdom, 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 United Kingdom: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |

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.
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.
About 98 per cent of UK oil and gas production comes from offshore fields, and the services industry in Aberdeen has been a leader in offshore technology.
The Dangerous Substances and Explosive Atmospheres Regulations 2002 require employers to identify and classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment in them.
Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so ATEX-certified products can be sold there without UKCA, while Northern Ireland still requires CE.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In United Kingdom. A UK device lives with rain, salt spray and hosing down rather than fine dust, and coverage can be patchy across a platform, terminal boundary or rural site. IP68 sealing and a rugged build are aimed at that duty, while 4G LTE, Wi-Fi and GNSS help. IP68 is not explosion protection.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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 designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.

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.
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.
