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 Johor Bahru and Pasir Gudang. Johor's heavy industry sits at Pasir Gudang and Pengerang, where international contractors and EPCs often arrive with European and international documentation. A reviewer there would look for ATEX and IECEx evidence side by side for a handheld, and a dual route reduces duplicated paperwork. IS-04Z1 certification is in progress and no certificate has been issued.

Questions · Johor Bahru
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Johor Bahru 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 ATEX and IECEx mobile phone in Johor Bahru 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.
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 Johor Bahru and Pasir Gudang would use it?
Likely candidates are port liquid bulk terminals, petrochemical and oleochemical plants, refinery and petrochemical process units (pengerang), fuel and chemical storage. 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 Johor Bahru and Pasir Gudang?
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 Johor Bahru and Pasir Gudang.
How does Johor Bahru's climate affect handheld devices outdoors?
An equatorial climate with high humidity, around 2,350 mm of rain a year and steady warm temperatures means moisture ingress and condensation are the main concerns. Devices typically need good sealing and cleaning routines, subject to the plant's rules.
Is Johor Bahru a good base for supplying Singapore and Johor sites?
Its position beside Singapore, the Iskandar special economic zone and the Causeway make cross-border supply practical, though customs procedures and border queues apply. Confirm duty treatment, radio type approval and site gate requirements with your freight agent.
Are Pasir Gudang and Pengerang the same site rules?
No. Pasir Gudang is an industrial estate with a port and many plants, while Pengerang is a separate complex east of Johor Bahru. Each operator sets its own procurement, HSE and classification rules, so ask the specific plant for its requirements.
