IECEx Smartphone in Denmark
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. This page explains what to look for in an IECEx smartphone for Denmark, and where the IS-04Z1 stands against that list today.

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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Denmark
More about Denmark that matters for portable equipment
Denmark: logistics and access
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: geography and layout
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.
Denmark: background
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.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Denmark. Danish acceptance rests on ATEX, so IECEx is useful where international contractors and engineering firms working out of Esbjerg bring a global specification, or where Danish operators have assets elsewhere. The certificate of conformity and schedule of conditions are read alongside the ATEX file. Neither is issued, and certification is in progress.

Specifying an 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 IECEx smartphone in Denmark today?
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.
What does an 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
Does Denmark's cool, windy climate matter for Ex handheld devices?
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.
What documentation is needed for an Ex phone in Denmark?
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.
Who classifies hazardous areas in Denmark?
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.
