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.
The IS-04Z1 is an explosion proof mobile phone designed for Zone 1 and Zone 21, from a wet deck 225 km west of Esbjerg to a fermentation building at Kalundborg and a biogas upgrading skid on Lolland. If you are specifying an explosion proof mobile phone for Denmark, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Denmark: Esbjerg, The Danish North Sea, Fredericia | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Denmark. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Denmark market guide.

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.
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.
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.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Denmark. Explosion proof is the everyday phrase, but a salt-water deck, a warm wet fermentation hall and an unmanned biogas yard need different thinking. Flameproof Ex d suits fixed equipment; the IS-04Z1 uses intrinsic safety for handhelds. Zone classification here comes from the emergency management agency's executive order. SAMS does not classify areas.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
The market guide for Denmark covers Esbjerg, The Danish North Sea, Fredericia, Kalundborg, among others. Site-level pages are linked below.
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.
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.
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.
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.
