Denmark: logistics and access
Port Esbjerg calls itself the world's largest base port for offshore wind activities and says it has been involved in shipping components to more than 65 offshore wind projects.
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 a rugged cell 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | 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 main operators, industrial areas and sites that the SAMS Denmark market guide covers.
Port Esbjerg calls itself the world's largest base port for offshore wind activities and says it has been involved in shipping components to more than 65 offshore wind projects.
Denmark imports about 12% of its energy but is also an exporter, and its electricity grid is connected by transmission lines to other European countries.
Denmark has North Sea oil and gas but ranked only 57th among net crude exporters in 2023 after ranking 32nd in 2008, so offshore work is mature, with decommissioning and maintenance a larger share.
North Sea natural gas projects began in 1984 and North Sea production made Denmark self-sufficient in energy in 1997, which explains the established offshore supply chain on the west coast.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Denmark. The North Sea and the west coast of Jutland treat weather sealing as a daily test: salt, wind and horizontal rain. IP68 sealing and a rugged build are aimed at exposed working, not at a pocket. IP68 is not explosion protection, which comes from the ATEX certificate and marking.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.

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.
Cold, wet and windy conditions affect battery life and touchscreen use with gloves, particularly offshore and at wind farms. Check the lowest rated ambient temperature on the certificate, the water ingress rating and whether touch input works with wet or gloved hands.
Typically the EU declaration of conformity, the certificate, the Ex marking details and instructions in the local language, which may be Danish or English depending on the operator. Request the site's equipment register template so supplier documents can be matched to it.
The classification of areas into zones comes from the emergency management agency under an executive order, while the employer's duty to assess explosion risk and hold an explosion protection document comes from the Danish Working Environment Authority. SAMS classifies nothing. Confirm the arrangement with the site operator for your plant.
