JTC and EDB describe Jurong Island as a hub for refining, olefins production and chemical manufacturing, with over 100 global companies.
Singapore's petrochemical sector is concentrated on Jurong Island, a roughly 3,000-hectare park with over 100 companies, and on Pulau Bukom. Refining, olefins and chemical plants, tank farms and polymer handling create Zone 1 and Zone 21 areas. This page explains what to look for in an ATEX and IECEx smartphone for Singapore petrochemical sector, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Singapore petrochemical sector: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | Singapore petrochemical sector: Cracker process units, Chemical derivative plants, Tank farms | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore Petrochemical. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
JTC and EDB describe Jurong Island as a hub for refining, olefins production and chemical manufacturing, with over 100 global companies.
ExxonMobil states that its 592,000-barrel-per-day Singapore refinery is fully integrated with its Singapore Chemical Plant.
Jurong Rock Caverns store crude oil, condensate, naphtha and gasoil underground, giving petrochemical plants on Jurong Island a large buffer of feedstock close by.
Aster's Bukom complex produces ethylene and refined products and is linked to its Jurong Island chemical complex by a 5 km subsea pipeline.
A world-scale renewable diesel plant using palm oil as feedstock was completed in Tuas in 2010, showing that petrochemical-type processing also exists outside Jurong Island.
Singapore produces no crude oil or feedstock of its own, so the petrochemical complex depends on imported feedstock arriving through jetties and tank farms.
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 petrochemical sector. With several international plant owners on Jurong Island, a reviewer would expect ATEX and IECEx evidence for handhelds used in cracker units, derivative plants and tank farms. The IS-04Z1 certification is in progress and only a datasheet is available now. Each plant decides which certificates it accepts, and policies can differ between neighbours.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are cracker process units, chemical derivative plants, tank farms, polymer handling and dust areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Common examples include cracker and reactor areas, pump and compressor houses, tank farms, jetties and polymer or powder handling, where dust zones can also arise. Zone 1 is common around seals and vents, but classification is set per plant, so ask for the area drawing.
Singapore has no crude oil or feedstock of its own, so material arrives by sea, is stored in tank farms and caverns, and is sent through pipelines. This creates busy jetty and transfer areas where equipment control is strict.
Not safely. Each plant runs its own contractor and equipment approvals, so acceptance at one plant does not carry over to a neighbour. Prepare a datasheet pack for each. Confirm requirements with the site operator at every plant.
