Heat and temperature class
Pilbara summers push site ambients past 45 degrees, where a handset that throttles at midday is no use. The marking target is II 2 G Ex ib IIC T4, with the ambient range on the certificate.
A Zone 1 / Zone 21 smartphone for crews on Australian LNG trains, offshore facilities, processing plants and remote mine sites. It is pre-launch: the IECEx certification program is under way, with ANZEx from the same test reports. Often searched for as an “explosion proof phone”, the IS-04Z1 uses intrinsic safety as its protection concept.
Launching Q4 2026 · IECEx and ANZEx certification program in progress
Australian classified area work sits in a few very large sites, far apart. The North West Shelf and the Pilbara are thousands of kilometres from the eastern seaboard, Darwin serves the Browse Basin, and Curtis Island anchors the Queensland coal seam gas chain.
Operators and contractors such as Woodside Energy, Chevron Australia and INPEX need an explosion proof mobile phone they can carry into classified areas at Karratha and the Burrup Peninsula, Onslow, Western Australia and Darwin. The IS-04Z1 is designed for Zone 1 and Zone 21 duty there.
Each specification below is a design target mapped to a condition Australian crews meet as routine. Certification will confirm the marking and the ambient range.
For evaluators in Australia, the IS-04Z1 explosion proof mobile phone is designed around these points: Heat and temperature class; Dust as well as gas; Remote sites and roster length; Gloves, drops and vibration; Connectivity across the site; Fleet management for rostered crews.
Pilbara summers push site ambients past 45 degrees, where a handset that throttles at midday is no use. The marking target is II 2 G Ex ib IIC T4, with the ambient range on the certificate.
Coal dust and some mineral-processing and grain dusts make Zone 21 a live classification here; iron ore and alumina are not normally combustible. The device is designed for Zone 21 dust as well as Zone 1 gas, sealed to IP68.
Where the nearest replacement is a flight away, a twelve hour shift is the normal case. The 4,000 mAh battery is sized for a full roster day with radio, camera and GNSS running.
Designed for glove operation and built rugged for drop, shock and vibration, which is what a device meets in a light vehicle on a haul road.
4G LTE, Wi-Fi, Bluetooth and NFC cover the plant and carrier networks, and four constellation GNSS holds a position down in a pit. Push to talk runs on the same device.
Android 16 with EMM and MDM support gives enrolment, remote lock, remote wipe and controlled updates, which matters when handsets rotate between crews and contractors.
Australia is in the IECEx system and AS/NZS 60079 is harmonised with IEC 60079, so an IECEx Certificate of Conformity is what sites work from. ANZEx uses the same test reports. Both in progress.
What your HSE and electrical teams will ask for is the certificate, not the brochure. Australia participates directly in the IECEx system and AS/NZS 60079 is harmonised with IEC 60079, so an IECEx Certificate of Conformity is the practical basis for equipment in a classified area. The ANZEx scheme issues a national certificate from the same test reports, and TestSafe Australia is the best known certification body. Because the handset carries radios, the program also covers ACMA requirements and the RCM mark.
Underground coal is the exception. Coal mine safety is regulated at state level through Resources Safety and Health Queensland and the NSW Resources Regulator, and underground coal equipment is Group I, a different regime from the Group II surface certification this device targets. A device accepted in a Zone 1 surface area is not automatically accepted underground, so confirm the group. Offshore facilities in Commonwealth waters sit under NOPSEMA, so the handset must also appear in the safety case.
Typical Zone 1 and Zone 21 duty for the IS-04Z1 explosion proof mobile phone in Australia includes: Turnaround and simultaneous operations on an LNG train; Surface mining and mineral processing plants; Offshore platforms, FPSOs and supply vessels; Refineries, import terminals and tank farms.
On a Karratha or Curtis Island shutdown the critical path is information, not steel. A permitted handset lets a technician photograph a flange, confirm an isolation and reach the coordination room from the work front.
Crushing, screening and materials handling carry combustible dust classification, and fuel farms add gas zones. Crews in the Pilbara and the goldfields carry one device for the work order, the photograph and the call.
Facilities in the Carnarvon, Browse and Bonaparte basins run long rotations with limited bandwidth and strict device rules. A Zone 1 handset supports handover notes, defect photographs and permit closeout on deck.
Geelong, Lytton and the import terminals that replaced the closed refineries run tank farms, loading gantries and vapour recovery in classified areas. Gauging and loading checks get logged where they are taken.
Nothing ships before certification completes, so the useful work now is specification and evaluation. Four steps take an Australian site from enquiry to pilot without any claim that cannot be supported.
Send the zone, gas group, temperature class and ambient range you work to, and say whether the fleet goes offshore, underground or both. That is enough to tell you whether this device fits.
You get the technical datasheet and a schedule of which certifications are in progress, what each covers and the expected sequence, written to drop into a tender response.
Evaluation units go out once certification allows it. One crew, one roster, on your own site network and your own MDM, tests more than a specification comparison ever does.
Supply for Australia and New Zealand is being built around distributors who hold site access, carry spares and turn repairs around locally. Pre-launch pricing is on request.
Send your site, zone and gas group, and we will answer for your plant rather than in general.
Ask about Australia →Not yet. The device is pre-launch and every certification, IECEx included, is in progress. Nothing should be planned into a classified area until the Certificate of Conformity is issued.
For surface and process industry work, in practice yes. Australia is in the IECEx system and AS/NZS 60079 is harmonised with IEC 60079. An ANZEx certificate is issued where a specification names it.
No. Underground coal is Group I equipment, regulated by the states through Resources Safety and Health Queensland and the NSW Resources Regulator. This device targets Group II for Zone 1 and Zone 21.
Zone 1 and Zone 21, gas and dust. The ATEX marking target is II 2 G Ex ib IIC T4, with NEC 500 Class I Division 1 also in the program.
It is designed for that, with a rugged build and IP68 sealing. The figure that matters for compliance is the ambient temperature range printed on the certificate.
Launch is Q4 2026. Until then you can request the datasheet, register a requirement for the first allocation, or join the pilot program for an evaluation unit.
Warranty and service run through the Australian partner SAMS is appointing. Repair of certified Ex equipment must be done by a facility recognised for that work.
There is no list price while certification is in progress. Pricing is quoted in writing against quantity and configuration, and for Australian sites the questions that usually decide a tender are service related: who holds stock in country, the turnaround on a replacement, and the repair route for certified equipment.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Australia. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
We are appointing distributors with mining and industrial supply relationships, site access, and the ability to hold stock and turn repairs around in country. Talk to us before the Q4 2026 launch.
