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.

Questions · Singapore Refinery
Frequently asked questions
Can we buy an IECEx mobile phone 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 mobile phone in Singapore Refinery 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.
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.
How do I become a SAMS distributor for Singapore refineries?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Singapore refineries.
Can I use a phone inside a Singapore refinery?
One refinery on Jurong Island publishes a ban on mobile phones and other electrical or electronic equipment in its process plant and classified hazardous areas. Devices certified for the zone may be allowed only with prior approval, so ask your sponsor before the visit.
What does a refinery visit involve in practice?
Typically a visitor pass at the island checkpoint, a plant security pass, an indemnity form, security screening, declaration of electronic equipment and an escort by a named sponsor for the whole visit. Allow extra time at the gate and arrive with approved paperwork.
Do hydrogen units change the marking needed?
Hydrogen is a Group IIC gas, so any unit handling it can call for IIC equipment, whereas many fuels fall in IIA or IIB. The IS-04Z1 target marking includes IIC but is not yet issued. Ask the refinery which units hold hydrogen.
