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 Edinburgh, Leith and the Forth. Leith's offshore wind foundation handling and Grangemouth's petrochemical operations attract international contractors who often work to IECEx documentation. The target is a certificate of conformity and a schedule of conditions that a project engineer can read against the specific area. That paperwork does not exist yet and must be confirmed once issued.

Questions · Edinburgh
Frequently asked questions
Can we buy an IECEx smartphone in Edinburgh today?
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.
What does an IECEx smartphone in Edinburgh cost?
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.
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 Edinburgh, Leith and the Forth would use it?
Likely candidates are port and offshore wind foundation handling, petrochemical process units at grangemouth, fuel import and storage terminal at grangemouth, ethane import and 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.
How does Edinburgh's wind and sea fog affect equipment used outdoors?
Edinburgh is known for wind, and easterly haar brings damp sea fog, so devices used on the waterfront need good ingress protection and cleaning. Typically workers also note reduced visibility, so check screens, torches and alarms against site conditions.
Do UK explosive-atmosphere rules apply in Scotland?
Yes. The Dangerous Substances and Explosive Atmospheres Regulations apply across Great Britain, and the Health and Safety Executive enforces them with local authorities. Employers must classify areas and control ignition sources, so ask sites for their hazardous-area records.
What is changing at Grangemouth that affects buyers?
Petroineos ended crude processing at the Grangemouth refinery in 2025, and the site is becoming a fuels import, storage and distribution terminal. The adjacent INEOS complex still operates the UK's last ethylene cracker. Contractor needs may therefore differ from a few years ago, so ask the operator for current requirements.
