The IS-04Z1 is an intrinsically safe Zone 1 and Zone 21 handset for people who work inside classified areas on Jurong Island, at Pulau Bukom and around the Tuas terminals: process operators, inspection and maintenance engineers, turnaround crews and the WSH and IT teams who equip them. An IMDA equipment registration is valid for five years, renewal is filed through the GoBusiness portal at least two months before expiry, and suppliers must keep test reports and technical files for five years. Distribution partners for Singapore are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Singapore has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.

| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Singapore market guide covers.
Energy and chemicals is Singapore's second-largest manufacturing sector, with more than 100 global chemicals companies operating here, which keeps a steady flow of maintenance and turnaround work in classified areas.
Singapore adopts the IEC 60079 series as SS EN 60079, and area classification drawings are expected for dangerous-goods premises and Major Hazard Installations, so a zone drawing is the starting point for equipment selection.
Land is scarce, so Singapore stores hydrocarbons underground and builds industry on reclaimed ground: Jurong Island was formed by joining seven islands, and storage caverns free up about 150 acres of surface land.
Natural gas now supplies over 90 percent of Singapore's electricity generation, up from under 20 percent in 2000, and the LNG terminal sends out about 9 million tonnes a year as its average capacity.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Singapore. A marking check in Singapore turns on gas group. Hydrogen and acetylene (IIC) are handled on Jurong Island alongside ethylene oxide (IIB), so a device marked only IIB is unusable on parts of the island. The target II 2 G Ex ib IIC T4 is read against that, with Zone 21 evidence for powder and cement.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Singapore yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
The market guide for Singapore covers Jurong Island, Pulau Bukom, Seraya and Merbau, Pulau Sebarok and Pulau Busing, among others. Site-level pages are linked below.
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.
The Ministry of Manpower covers workplace safety duties for explosive atmospheres, and the Civil Defence Force covers flammable-material storage and dangerous-goods premises. In practice the site operator's own hazardous-area drawings and equipment standard decide what may enter a zone, so check them before shipping anything.
Visitors normally collect a Jurong Island visitor pass at the checkpoint, then receive a separate site pass from the plant they visit. One refinery's published rules ban phones in process and classified areas and ask visitors to declare electronic equipment. Expect similar screening and ask your sponsor in advance.
Hydrogen and acetylene, both gas group IIC, are handled on the island next to ethylene oxide in IIB, so a handset rated only to IIB cannot be used in some areas. The IS-04Z1 target is Ex ib IIC. Certification is in progress, so check the final certificate.
