Field notes · Singapore
More about Singapore that matters for portable equipment
Singapore: logistics and access
Singapore sold 56.775 million tonnes of marine fuel in 2025, making it the largest bunkering port in the world by a wide margin and keeping fuel handling and barge work active around the clock.
Singapore: projects and investment
SLNG plans a second LNG terminal offshore, slated to operate by the end of the decade, in addition to the existing Jurong Island terminal, so new gas-handling sites are expected over the coming years.
Singapore: rules and approvals
IMDA registers telecommunications equipment under a supplier's declaration approach. Cellular mobile devices, including 5G and LTE, fall under Simplified Equipment Registration, while base stations and similar higher-risk products need a recognised certification body.
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. IECEx is the reference scheme for the international operators on Jurong Island, including ExxonMobil, Singapore Refining Company and Aster Chemicals and Energy, and for visiting turnaround contractors. Reviewers would read the certificate of conformity together with its schedule of conditions. The IS-04Z1 IECEx certificate is in progress and, with IMDA registration, is needed before any use.

- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Singapore
Frequently asked questions
Can we buy an IECEx mobile phone in Singapore 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 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.
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 sites in Singapore does this cover?
The market guide for Singapore covers Jurong Island, Pulau Bukom, Seraya and Merbau, Pulau Sebarok and Pulau Busing, among others. Site-level pages are linked below.
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.
Which Singapore authorities matter for hazardous-area equipment on site?
The Ministry of Manpower covers workplace safety duties for explosive atmospheres, and the Civil Defence Force covers flammable-material storage and dangerous-goods premises. In practice the site operator's own hazardous-area drawings and equipment standard decide what may enter a zone, so check them before shipping anything.
What should a visitor expect when bringing a handheld device onto Jurong Island?
Visitors normally collect a Jurong Island visitor pass at the checkpoint, then receive a separate site pass from the plant they visit. One refinery's published rules ban phones in process and classified areas and ask visitors to declare electronic equipment. Expect similar screening and ask your sponsor in advance.
Why does gas group IIC matter for Jurong Island?
Hydrogen and acetylene, both gas group IIC, are handled on the island next to ethylene oxide in IIB, so a handset rated only to IIB cannot be used in some areas. The IS-04Z1 target is Ex ib IIC. Certification is in progress, so check the final certificate.
