IECEx Smartphone in Wales
Two LNG terminals, South Hook on a former refinery site and Dragon LNG on a former Gulf refinery site, were built from 2006 and could eventually supply about 25% of the UK's gas needs. It hosts Valero's Pembroke refinery and the South Hook and Dragon LNG terminals, so Zone 1 work arises at process units, tank farms and gas handling areas. If you are specifying an IECEx smartphone for Wales (Milford Haven Waterway), this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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 Wales (Milford Haven Waterway). The Pembroke refinery and the South Hook and Dragon LNG terminals work with international engineering and turnaround contractors, many of whom hold IECEx-based paperwork. The aim is a certificate of conformity plus a schedule of conditions that an engineer can read against a particular area. It is not yet available.

Questions · Wales
Frequently asked questions
Can we buy an IECEx smartphone in Wales 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 Wales 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 Wales (Milford Haven Waterway) would use it?
Likely candidates are refinery process units, lng storage and regasification, crude and product jetties, tank farms. 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.
Do Welsh sites follow the same Ex marking rules as the rest of Great Britain?
Yes, Wales is within Great Britain's product rules, where equipment for explosive atmospheres is normally supplied with UKCA marking and CE-marked ATEX equipment has been widely accepted under transitional arrangements. Check the current position and any site-specific rules with the operator before supplying handheld devices.
How does the Welsh climate affect devices used outdoors?
Wales is mild but wet and windy, with salt spray at coastal terminals such as Milford Haven. Ingress protection, corrosion resistance and condensation tolerance are more important than extreme temperature ratings. Ask the site about its own environmental requirements for portable electronics.
What hazardous-area work is there in Wales?
The Milford Haven Waterway in Pembrokeshire hosts Valero's Pembroke refinery, which began operating in 1964, and the South Hook and Dragon LNG terminals. Zone 1 work arises at process units, tank farms and gas handling areas. Confirm requirements with each operator's HSE and procurement teams.
