IECEx Smartphone 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. This page explains what to look for in an IECEx smartphone for Singapore refineries, and where the IS-04Z1 stands against that list today.

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.

- 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 smartphone in Singapore Refinery today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an IECEx smartphone in Singapore Refinery cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 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.
