Singapore: geography and layout
Land is scarce, so Singapore stores hydrocarbons underground and builds industry on reclaimed ground: Jurong Island was formed by joining seven islands, and storage caverns free up about 150 acres of surface land.

ATEX and IECEx Mobile Phone in Singapore
The IS-04Z1 is an intrinsically safe Zone 1 and Zone 21 handset for people who work inside classified areas on Jurong Island, at Pulau Bukom and around the Tuas terminals: process operators, inspection and maintenance engineers, turnaround crews and the WSH and IT teams who equip them. This page explains what to look for in an ATEX and IECEx mobile phone for Singapore, and where the IS-04Z1 stands against that list today.

Field notes · Singapore
More about Singapore that matters for portable equipment
Singapore: infrastructure
Natural gas now supplies over 90 percent of Singapore's electricity generation, up from under 20 percent in 2000, and the LNG terminal sends out about 9 million tonnes a year as its average capacity.
Singapore: rules and approvals
The Ministry of Manpower enforces explosive-atmosphere duties under the Workplace Safety and Health Act, while the Singapore Civil Defence Force regulates flammable-materials storage under the Fire Safety Act.
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.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Singapore. A Singapore HSE or procurement reviewer on Jurong Island would expect IECEx evidence, since the sheet names IECEx and IMDA registration as the route in progress. ATEX alongside it helps the multinational operators and EPCs whose global standards already reference both. No certificate has been issued for the IS-04Z1, so any review today concerns the schedule and the datasheet.

Specifying an ATEX and IECEx mobile phone for Singapore
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- 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 ATEX and 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 ATEX and 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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
Are ATEX and IECEx markings both understood in Singapore?
Singapore adopts IEC 60079 as SS EN 60079, and both IECEx and ATEX certificates are built on that technical base. Many operators accept either, but an individual refinery or yard may name one scheme in its specification, so confirm with the operator's HSE or instrumentation team.
Do phones and tablets sold in Singapore need IMDA registration?
Cellular mobile devices are generally registered with IMDA under the Simplified Equipment Registration route, which relies on a supplier's declaration of conformity. The registration is valid for five years, and the registering supplier is typically a local entity. Confirm the exact route for a specific model with IMDA or a local compliance adviser.
How does the IS-04Z1 cope with island and boat-access sites such as Bukom?
The design pairs a 4,000 mAh battery with IP68 sealing so the unit lasts through a shift where a spare may be a boat away. Charging stays in a safe area. Test battery life on a typical round and confirm access rules with the island operator.
