Integrated site
Bukom is linked by subsea pipeline to chemical units on Jurong Island, so contractors may work across both locations.

IECEx Mobile Phone in Pulau Bukom Refinery
Singapore's equatorial climate gives consistent heat and humidity with frequent heavy showers, which affects open-air process plant, tank farms and jetties year round. Since April 2025 the complex has been owned by CAPGC and operated as the Aster Energy and Chemicals Park, so process units create Zone 1 areas. If you are specifying an IECEx mobile phone for Pulau Bukom, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Pulau Bukom that matters for portable equipment
Pulau Bukom: geography and layout
Pulau Bukom is a restricted-access island of about 145 hectares, roughly 5 km south of mainland Singapore in the Singapore Strait, with a small companion islet to its south.
Pulau Bukom: industry on the ground
Singapore's energy and chemicals sector is its second-largest manufacturing sector, so the island's refinery and cracker sit within a national cluster of more than 100 chemicals companies.
Pulau Bukom: infrastructure
The Bukom and Jurong Island sites are joined by a 5 km subsea pipeline, which carries product between islands and reduces ship-to-shore transfers.
Pulau Bukom: background
Pulau Bukom has been the site of Singapore's first oil refinery since 1961, and the island has hosted refining, trading and related services for more than six decades.
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 Pulau Bukom. Bukom is now run as an integrated energy and chemicals park, so international EPCs and visiting contractors may bring their own equipment rules. The IECEx route is meant to give them one certificate of conformity and a schedule of conditions to read. For the IS-04Z1 both documents are still pending, and no issue date exists.

Questions · Pulau Bukom Refinery
Frequently asked questions
Can we buy an IECEx mobile phone in Pulau Bukom Refinery 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 IECEx mobile phone in Pulau Bukom Refinery cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 areas at Pulau Bukom would use it?
Likely candidates are refinery process units, ethylene cracker, crude and product tank farms, jetties. 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.
Is the Bukom site connected to Jurong Island?
Yes. A 5 km subsea pipeline links Aster Bukom to Aster's chemical complex on Jurong Island, so the two sites run as one integrated operation. Expect shared safety standards between sites, but confirm site-specific rules with each location.
What process areas are on Bukom?
Aster describes Bukom as a fully integrated site focused on refining and ethylene production. That means crude units, cracker furnaces, tank farms and jetties, where Zone 1 and Zone 2 gas areas are typical. Exact zoning is set by the operator's area classification.
How does island access affect bringing handhelds to Bukom?
The site restricts access to personnel with security passes, and staff travel by ferry, so equipment is usually checked before the crossing. Ask the operator's security and HSE teams what device checks apply, and plan enrolment and charging before travel. Confirm the current process with the site operator.
