IECEx Mobile Phone in Singapore Refinery
The refinery's published rules state that mobile phones and other electrical or electronic equipment must not be used in the process plant area or other classified hazardous areas. Process units, tank farms and jetties create Zone 1 and Zone 2 areas. If you are specifying an IECEx mobile phone for Singapore refineries, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Singapore refineries that matters for portable equipment
Singapore refineries: people and language
Staff and visitors reach Jurong Island by bus from Lakeside MRT or Jurong East, with some employers running private shuttles from the checkpoint to their premises.
Singapore refineries: industry on the ground
Singapore Refining Company operates a Jurong Island refinery capable of processing 290,000 barrels of crude oil a day, supplying fuel products and chemical feedstocks to domestic and export markets.
Singapore refineries: logistics and access
The refinery's main entrance is reached via Merlimau Road along Jurong Island Highway, after a stop at the Jurong Island Checkpoint where visitors collect a visitor pass.
Singapore refineries: background
Pulau Bukom has been home to Singapore's first oil refinery since 1961, and Aster's Bukom complex continues to refine crude alongside ethylene production.
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 refineries. Three refineries on Jurong Island and Pulau Bukom share a contractor pool that includes international EPCs. IECEx offers them one certificate of conformity with a schedule of conditions to compare across sites. The IS-04Z1 has neither document yet, because certification is in progress.

Specifying an IECEx mobile phone for Singapore Refinery
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 Refinery
Frequently asked questions
Can we buy an IECEx mobile phone in Singapore 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 Singapore 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 Singapore refineries would use it?
Likely candidates are refinery process units, crude and product storage, jetties, utility and cogeneration areas. 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.
How large are the refineries on Jurong Island?
One refinery states a crude capacity of 290,000 barrels a day, and other operators share the island. The scale means many contractors, so expect formal induction, permits and equipment checks for any portable electronics.
Who should a supplier contact at a refinery?
Refineries usually route equipment queries through procurement and the process safety or HSE function, with reliability and maintenance teams as end users. Ask your sponsor for the correct contacts and the current approved-equipment procedure.
Do all Singapore refineries accept the same devices?
No. The refineries use their own approval and contractor systems, so acceptance at one does not carry over to another. The IS-04Z1 has no certificate yet. Send the datasheet to each operator's procurement and HSE teams and confirm with the site operator.
