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.

Petrobras began processing oil shale in 1953 with its Petrosix technology, and in 2006 its industrial retort could treat 260 tonnes of shale an hour.
Brazil: rules and approvals
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 · 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 Brazil. A marking check on a Brazilian jetty, deck or unit would read the temperature class against the drawing, since T4 is the figure usually checked, along with gas group and the INMETRO mark. Heat and salt-laden air at Suape, Santos and Camaçari are common. The marking target is II 2 G Ex ib IIC T4, still in progress.

Specifying an Ex-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 Ex-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 Ex-proof cell phone in Brazil 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.
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 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.
