IECEx Mobile Phone in Singapore Shipyard
Pioneer Yard has a 1,400 metre quay with 8 to 10 metres of depth, with a second quay of 350 metres, giving long alongside berths for repair work. Repair, conversion and newbuild work brings Zone 1 conditions into tanks, cargo spaces and paint areas. This page explains what to look for in an IECEx mobile phone for Singapore shipyards, and where the IS-04Z1 stands against that list today.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Singapore shipyards: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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 Singapore shipyards. With a mix of local yards and visiting vessels, many yard safety teams have seen IECEx certificates before. They would expect the certificate of conformity and the schedule of conditions to be shown together. The IS-04Z1 has neither document yet, because the IECEx programme is still in progress.

Questions · Singapore Shipyard
Frequently asked questions
Can we buy an IECEx mobile phone in Singapore 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 Singapore Shipyard 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 Singapore shipyards would use it?
Likely candidates are vessel tank spaces, dry dock and repair work, paint and coating shops, offshore conversion. 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 large docks create special conditions?
Large graving docks hold very big vessels and many contractors at once, so crowding, crane lifts and hot work overlap. Hazardous-area controls are managed per vessel by the yard's safety team and the owner's representative.
Which Singapore shipyards are major sites for Zone 1 work?
Seatrium's yards at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard are the large repair and conversion sites, and other yards operate in the Jurong area. Zone 1 conditions arise inside tanks and pump rooms during repair and coating work.
Do gas-free procedures replace the need for certified equipment?
Not automatically. Tank entry and hot work normally follow per-vessel gas-free and permit procedures set by the yard, and some yards still require certified equipment in certain spaces. The IS-04Z1 has no certificate yet. Ask the yard safety department which rule applies.
