The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
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 Surabaya and the Gresik industrial area. A reviewer at Tanjung Perak, Gresik or the Rungkut estate would expect certificate evidence matched to the marking, with its schedule of conditions. The IS-04Z1 evidence is in progress. A dual ATEX and IECEx route helps because the area mixes port, chemical, fertiliser and cement operators.

Questions · Surabaya
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Surabaya today?
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.
What does an ATEX and IECEx smartphone in Surabaya cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Surabaya and the Gresik industrial area would use it?
Likely candidates are port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas, industrial estate chemical plants. 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 Surabaya and the Gresik industrial area?
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 Surabaya and the Gresik industrial area.
Is the climate in Surabaya hard on handheld equipment?
Temperatures are steady, around 23 to 31 degrees, but the wet season from October to May brings heavy rain and humidity, and coastal air adds salt. Devices typically need good ingress protection and cleaning routines for exposed use.
Which industrial areas around Surabaya matter for hazardous-area equipment?
The wider metropolitan area includes Gresik, Sidoarjo and other satellite cities with port-side and industrial plants. Typical hazards include fuel, chemical and bulk handling, so ask each operator for its zone classification and device approval requirements.
Does Gresik count as part of the Surabaya market?
Yes in practice. Gresik lies about 25 kilometres north-west of Surabaya, and its fertiliser and cement works are major buyers of safety equipment. Requirements are set plant by plant. Confirm with each site operator's safety function.
