Energy and water security
JTC states that the island also hosts power generation and desalination plants and supports Singapore's natural gas supply, so work there covers utilities as well as process plants.

ATEX and IECEx Mobile Phone in Jurong Island
Jurong Island is Singapore's integrated energy and chemicals park of about 3,000 hectares, formed from seven small islands and developed by JTC. It hosts over 100 global companies in refining, olefins and chemical manufacturing, so gas and vapour (Zone 1) areas are widespread. This page explains what to look for in an ATEX and IECEx mobile phone for Jurong Island, and where the IS-04Z1 stands against that list today.

Dense cluster
Many operators sit close together, so contractors often move between plants that each run separate permit and approval systems.
Field notes · Jurong Island
More about Jurong Island that matters for portable equipment
Jurong Island: industry on the ground
Singapore Refining Company runs a refinery on Jurong Island able to process 290,000 barrels of crude a day, producing fuel products and chemical feedstocks for domestic and export markets.
Jurong Island: industry on the ground
Singapore produces no crude oil or feedstock of its own, so Jurong Island plants run on imported material delivered by sea, which makes jetties, tank farms and transfer lines a constant feature of the site.
Jurong Island: infrastructure
The caverns hold about 9.2 million barrels across five isolated storage caverns and store crude oil, condensate, naphtha and gasoil, so vapour-handling surface facilities sit above a very large underground inventory.
Jurong Island: logistics and access
Visitors enter through the Jurong Island Checkpoint, where they exchange an identity card or passport for a Jurong Island visitor pass before travelling on to the plant they are visiting.
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 Jurong Island. Jurong Island hosts over 100 energy and chemicals companies, including operators such as ExxonMobil, Shell and BASF, so reviewers differ by plant. Many would expect certificate evidence for both ATEX and IECEx because their parent companies operate internationally. The IS-04Z1 has no certificate yet; certification is in progress.

Questions · Jurong Island
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Jurong Island today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an ATEX and IECEx mobile phone in Jurong Island 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 areas at Jurong Island would use it?
Likely candidates are refinery and cracker process units, chemical and petrochemical plants, lng storage and loading, underground rock cavern storage. 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.
Can I bring a mobile phone into a plant on Jurong Island?
Usually not into process or classified areas unless the equipment is approved for the zone and the operator permits it. One refinery on the island publishes a ban on phones and other electronic equipment in those areas. Ask your site sponsor which devices are accepted and whether a permit is needed.
How large is refining activity on Jurong Island?
One refinery on the island states a crude processing capacity of 290,000 barrels a day, and other chemical and refining operators share the same island. Because feedstock arrives by sea, expect busy jetty, tank and pipeline areas where Zone 1 and Zone 2 conditions are common.
Can contractors move one device between plants?
Not automatically. Each plant runs its own contractor and equipment approvals and permit system, so a device accepted at one plant may need separate approval at another. Ask each plant's HSE team for its process, and plan enrolment and permits per client.
