Brazil: rules and approvals
An OCP may issue its certificate on the basis of an IECEx test report and quality assessment report if they are equivalent, but only under Model 5, so IECEx work helps without replacing national certification.

ANATEL's CERTIFICA platform requires the local applicant's legal representative to sign a product warranty and technical support declaration, and certification templates need ICP-Brasil digital signatures.

The pre-salt oil fields lie within Brazil's exclusive economic zone and extend along the coast from Espirito Santo to Santa Catarina, with reserves estimated at more than 50 billion barrels.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Brazil. Explosion proof is the common phrase, but in Brazil the compliant answer is a certified product under Portaria INMETRO 115 of 2022, whatever the protection concept. Flameproof Ex d fits fixed equipment in refining at Paulínia or Duque de Caxias; the IS-04Z1 uses intrinsic safety instead. Area classification is the operator's, not SAMS's.

Specifying an explosion proof cell phone for Brazil
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 · Brazil
Frequently asked questions
Can we buy an explosion proof cell phone in Brazil 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 explosion proof cell phone in Brazil 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which sites in Brazil does this cover?
The market guide for Brazil covers Santos Basin pre-salt, Campos Basin, Duque de Caxias, Paulínia, 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.
Where does hazardous-area work concentrate in Brazil?
Typically offshore pre-salt platforms and floating units off the south-east coast, onshore refineries and terminals, petrochemical complexes and ethanol and sugar mills. Each operator issues its own area classification, so request the zone drawing, gas or dust group and temperature class before choosing equipment.
What does ANATEL require for a smartphone sold in Brazil?
Radio equipment needs ANATEL certification through the CERTIFICA platform, using a local legal representative who signs the warranty and technical support declaration, with digital signatures from ICP-Brasil on templates. Requirements change, so confirm current steps with ANATEL or an accredited certification body.
Is an IECEx or ATEX certificate enough for Brazil?
No: certification is compulsory and issued by an OCP accredited by INMETRO, under Portaria INMETRO 115 of 2022. IECEx data normally supports the Brazilian file without replacing it. The IS-04Z1 has no certificate of any kind yet. Check requirements with Petrobras or your contract's equipment specification.
