Portugal: background
The Sines hard coal power plant operated from 1985-1989 until January 2021 and coal-fired generation ended in 2021, so former coal sites are being redeveloped.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, aimed at the refining and polymer complex at Sines, the chemical plants at Estarreja and the pulp, cement and mining sites in between. In 2021 Portugal imported 2.8 billion cubic metres of LNG from Nigeria, almost 50% of its gas imports that year, so ship-to-shore LNG operations are central to gas supply. An intrinsically safe mobile phone distributor in Portugal would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Portugal has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Portugal. 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 Portugal market guide.
The Sines hard coal power plant operated from 1985-1989 until January 2021 and coal-fired generation ended in 2021, so former coal sites are being redeveloped.
Oil made up 44% of Portugal's total energy supply in 2023, so fuel storage, port terminals and distribution depots form a large part of the classified-area infrastructure.
The Sines LNG import terminal has three storage tanks with a total capacity of 390,000 cubic metres and regasification capacity of 5.6 million tonnes a year, making Sines Portugal's key gas import site.
In 2000 about 85% of Portugal's energy was imported, so most fuel and gas reaches the country through port terminals rather than domestic fields.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Portugal. Large sites and small crews mean a single operator may cover long rounds across Sines, Estarreja or a pulp mill at Figueira da Foz. An intrinsically safe handheld lets one person log findings, photograph equipment and run a work-order app without returning to a control room for each entry.
A distributor for Portugal would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.

Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Portugal.
Portugal is an EU member, so ATEX Directive 2014/34/EU applies to equipment and Directive 1999/92/EC to workplace zoning. Zone 1 and Zone 2 devices should carry CE and Ex markings with instructions in Portuguese where required. Operators usually add their own permit and registration procedures.
Sines hosts Portugal's LNG import terminal, with three storage tanks totalling 390,000 cubic metres and a regasification capacity of 5.6 million tonnes a year. Terminal and port operators set their own induction and device rules, so confirm them before sending equipment.
Yes, Zone 21 dust protection belongs to the same certification programme as the gas marking. In pulp, cement and mineral processing the powder area is the plant, not a corner of it, so check the final certificate and the site's own dust classification with the operator.
