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 Keppel Shipyard (now Seatrium yards), Singapore. Ship owners, classification bodies and visiting contractors at the yards are international, so IECEx is a convenient reference for gas-free work on tanks and cargo spaces. The certificate of conformity and schedule of conditions would be reviewed. For the IS-04Z1 these remain targets, as certification is in progress.

Questions · Keppel Shipyard
Frequently asked questions
Can we buy an IECEx mobile phone in Keppel Shipyard today?
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.
What does an IECEx mobile phone in Keppel Shipyard 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 Keppel Shipyard (now Seatrium yards), Singapore would use it?
Likely candidates are vessel tank and cargo spaces, offshore unit conversion, paint and solvent areas, dry dock work. 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.
Does the work differ between FPSO conversion and ordinary repair?
Conversion projects involve large process and tank systems that become classified areas when commissioned, while repair work is more tank-by-tank and short term. Expect tighter control of electronics on conversion hulls close to hydrocarbon systems. The vessel owner and yard HSE team set the rules for each project.
Is Keppel Shipyard still operating under the Keppel name?
Keppel's offshore and marine yards are now part of Seatrium, formed in 2023 from Sembcorp Marine and Keppel Offshore and Marine. Former Keppel yard sites in Singapore are now listed under Seatrium, so use that name when registering for contractor access or supplier approval.
Are older Keppel yard references still correct?
No. Seatrium was formed in 2023 and Keppel's yards now operate under it, and the Gul yard was sold to ST Engineering. Use current names when contacting yards. Details of individual Seatrium yards were not verified, so ask the company which yard serves your project.
