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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Singapore shipyards. Yards bring in large subcontractor gangs for each project. A managed pool of phones under EMM or MDM helps limit apps and access, and devices should be enrolled before they reach the yard. Charging belongs outside tanks in a safe area, and each yard sets its own network rules.

Questions · Singapore Shipyard
Frequently asked questions
Can we buy an industrial mobile phone in Singapore Shipyard 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 industrial mobile phone in Singapore Shipyard cost?
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.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
