The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Singapore marine and shipyard sector. A marking check for vessel tank and cargo spaces, described as Zone 1, would compare gas group and temperature class with the cargo history of the tank. Paint and coating vapours add solvent atmospheres. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued, and the yard decides.

Distributing the IS-04Z1 in Singapore Marine
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Singapore marine and shipyard sector yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Singapore marine and shipyard sector.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Singapore Marine
Frequently asked questions
Can we buy an Ex-proof smartphone in Singapore Marine 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 Ex-proof smartphone in Singapore Marine 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Singapore marine and shipyard sector would use it?
Likely candidates are vessel tank and cargo spaces, repair and conversion work, paint and coating areas, offshore unit conversion. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Singapore marine and shipyard sector?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Singapore marine and shipyard sector.
Does bunkering create hazardous areas around the port?
Fuel transfer between barges and ships can create temporary vapour zones around connections and vents, depending on the fuel. Port and operator procedures control ignition sources during transfer. Ask the barge operator or ship's officer what equipment may be used on deck.
Which Singapore yards handle gas carriers and floating production units?
Seatrium lists LNG and LPG carriers and floating production vessels among the vessels it repairs and converts at its Singapore yards. These ship types generally bring the strictest hazardous-area controls, so confirm yard and vessel rules with the project team.
Does one approval cover every shipyard in Singapore?
No. Yards and vessel owners set their own device rules, and the yard list here is not exhaustive. A device accepted at one yard may still need separate agreement at another. Confirm requirements with the yard safety team where the work will happen.
