Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Japan: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about Japan that matters for portable equipment
Japan: rules and approvals
As of July 2026 the Ministry of Health, Labour and Welfare lists eight registered examination bodies for this equipment, including TIIS and several bodies outside Japan.
Japan: rules and approvals
Since a January 2017 notice an IECEx test report can be submitted as the applicant's prior test results, and a certificate is valid for three years.
Japan: logistics and access
The Port of Nagoya in Ise Bay is described as Japan's largest and busiest trading port, handling about 10% of the country's trade by value, and has been run by the Nagoya Port Authority since 1951.
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 Japan. A Japanese reviewer at a coastal petrochemical complex would expect TIIS evidence, which the sheet lists as in progress, and IECEx. ATEX evidence also helps international contractors and global groups. A dual route lets one pack serve the complex's own review and visitors. No certificate has been issued.

Specifying an ATEX and IECEx mobile phone for Japan
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Japan
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Japan 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 Japan 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 sites in Japan does this cover?
The market guide for Japan covers Kashima, Mizushima, Chiba / Sodegaura, Yokkaichi, among others. Site-level pages are linked below.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
What radio approval does a phone need in Japan?
Radio equipment is covered by the Telec technical conformity scheme, and the certified-products database can be searched to check a model. Requirements depend on the radio technologies in the device, so confirm with a registered certification body before importing.
Can an IECEx report speed up approval in Japan?
Since 2017 an IECEx test report can be submitted as the applicant's prior test results, which can reduce testing, but the Japanese type examination certificate is still required, and it is valid for three years. Confirm the reports accepted with the chosen examination body.
Will a handset cope with typhoon-season humidity and salt air?
The IS-04Z1 has IP68 sealing, which helps with water, dust and salt-laden air. That is an ingress rating only. Ask for the datasheet's operating ranges and test a unit during a humid season round at a coastal site.
