Denmark: rules and approvals
Manufacturers who apply the ATEX provisions and affix CE and Ex markings may sell equipment anywhere in the EU without further requirements for those risks, so Danish buyers can use EU-wide certificates.

WhereDenmark
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Denmark: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Denmark
More about Denmark that matters for portable equipment
Denmark: projects and investment
Denmark expects to remain self-sufficient in oil until 2050 according to the cited article, so existing offshore and onshore oil facilities are likely to need maintenance work for years to come.
Denmark: industry on the ground
Coal supplied less than 11% of electricity in 2019 and coal-fired generation was scheduled to end by 2028, so biomass and gas plants are replacing coal sites.
Denmark: projects and investment
A target of 100% renewable electricity by 2030 and a wind turbine industry dating from the 1970s mean wind and green-energy projects are a large share of current construction work.
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 Denmark. Denmark is inside the EU, so ATEX is the product-side requirement and nothing national follows it. A reviewer would ask for the notified body certificate and CE marking, with an IECEx route helping offshore groups such as TotalEnergies EP Danmark and BlueNord, and contractors like Semco Maritime, who work across borders. Certification is in progress.

Specifying an ATEX and IECEx smartphone for Denmark
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 · Denmark
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Denmark today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an ATEX and IECEx smartphone in Denmark 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 sites in Denmark does this cover?
The market guide for Denmark covers Esbjerg, The Danish North Sea, Fredericia, Kalundborg, 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.
Do Danish offshore platforms require ATEX equipment?
Denmark applies ATEX Directive 2014/34/EU as an EU member, and the directive explicitly covers equipment used on fixed offshore platforms. Operators typically add their own approval, helicopter and survival-suit procedures. Confirm the platform operator's device rules well ahead of a trip.
Is the Danish North Sea still an active market for hazardous-area devices?
Yes, though the sector is mature. Oil and gas production began scaling in the 1980s and continues, with maintenance and decommissioning work. Other hazardous-area work comes from biogas, power and industrial plants. Confirm current projects with operators rather than relying on past production figures.
Is the phone suitable for biogas plants and offshore support work?
It is designed for Zone 1 gas and Zone 21 dust, with four-constellation GNSS and 4G LTE for lone working, but certification is in progress and no certificate exists. Suitability depends on the area classification and gas group at each plant. Check with the plant operator and request the datasheet.
