Portugal: who works there
Galp Energia, formed in 1999 from Petrogal, Gás de Portugal and Transgás, is Portugal's largest oil and gas group, with business units covering upstream, refining and midstream, commercial, and renewables.
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. This page explains what to look for in an IECEx mobile phone for Portugal, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Portugal: 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 |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |

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.
Operators and classified areas drawn from the SAMS Portugal market guide.
Galp Energia, formed in 1999 from Petrogal, Gás de Portugal and Transgás, is Portugal's largest oil and gas group, with business units covering upstream, refining and midstream, commercial, and renewables.
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.
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.
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 Portugal. Sines and Estarreja involve international groups such as Repsol and Dow, plus EPC and maintenance contractors, so IECEx offers a shared scheme beside ATEX. Ask for the certificate of conformity and its schedule of conditions, which fix the marking, ambient range and conditions of use. The IS-04Z1 has none yet issued, and the programme is in progress.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
The market guide for Portugal covers Sines, ZILS Alentejo, Estarreja, Matosinhos and Leça, 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.
Atlantic coastal sites are salt-laden and summers can be hot, so check the maximum ambient temperature on the certificate, the water and dust ingress rating and the condition of charging contacts. Sealed connectors and regular cleaning are typically recommended for coastal terminals.
Portugal has a hydrogen strategy aimed at reducing gas imports by 2030, so hydrogen projects may create new classified areas. Hydrogen belongs to a more demanding gas group than propane, so check the gas group marking of a device against the project's area classification.
Sites such as Sines or the Alentejo interior can be far from anyone who services equipment, so a reachable service route matters. SAMS has appointed no distributor yet. Before purchase, ask what repair, replacement and battery support would be available for your plant, and agree it in writing.
