Field notes · Portugal
More about Portugal that matters for portable equipment
Portugal: logistics and access
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.
Portugal: industry on the ground
Sines on the Atlantic coast hosts an important oil refinery and several petrochemical industries.
Portugal: projects and investment
Portugal aims to cover 80% of electricity consumption with renewables by 2030 and has developed a hydrogen strategy to reduce gas imports, which may add hydrogen-classified areas.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Portugal. A marking check in Portugal compares II 2 G Ex ib IIC T4 with the plant classification. Sines and Estarreja are the gas and vapour Zone 1 case. Pulp, cement and mineral processing make dust the defining zone, and a gas-only device is the wrong tool there, which is why the Zone 21 target matters.
The route · specification
Specifying an Ex-proof mobile phone for Portugal
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 · Portugal
Frequently asked questions
Can we buy an Ex-proof mobile phone in Portugal 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 Ex-proof mobile phone in Portugal cost?
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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which sites in Portugal does this cover?
The market guide for Portugal covers Sines, ZILS Alentejo, Estarreja, Matosinhos and Leça, 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 Portugal follow ATEX for handheld devices?
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.
Why is Sines important for hazardous-area work in Portugal?
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.
Is dust protection part of the programme?
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.
