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 Pohang. A reviewer at a steelworks would expect clear evidence for any handheld used near process gas systems, and international suppliers and plant-engineering contractors often bring ATEX or IECEx documents. The IS-04Z1 certification is in progress, so only a datasheet is available. POSCO decides which evidence it accepts.

Questions · Pohang
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Pohang 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 Pohang cost?
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.
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 Pohang would use it?
Likely candidates are steelworks process gas systems, coke-making and by-product gas, steel plant dust 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 Pohang?
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 Pohang.
Is Pohang humid or cold enough to affect equipment?
Winters are mild by Korean standards, with a January mean near 2 degrees, while summers reach about 26 degrees with the heaviest rain in August. Sea air and humidity are the main concerns, so devices typically need good sealing and routine cleaning.
How do I get equipment to Pohang?
Pohang is on the East Sea coast with a shipping port and road links, and most equipment arrives by road from other Korean ports or airports. Allow time for customs clearance and for site gate checks on electronic devices at the steelworks.
Do steelworks gases need a different marking from oil and gas sites?
They can. Coke-making and by-product gas systems may contain gases such as hydrogen or carbon monoxide, which affect the gas group needed, and plant dust areas need a dust classification. The IS-04Z1 has no certificate yet. Ask POSCO which gas and dust groups apply.
