Brazil: rules and approvals
Certification is carried out by an INMETRO-accredited product certification body, called an OCP, and Model 5 certificates, which include a quality system audit and surveillance, are valid for six years.

More about Brazil that matters for portable equipment
Brazil: background
Petrobras was created in 1953 under the slogan The Oil Is Ours, was given a legal monopoly, and is headquartered in Rio de Janeiro; its REDUC refinery began operating in 1961.
Brazil: rules and approvals
Portaria INMETRO No. 115 of 21 March 2022 sets the conformity assessment rules for electrical equipment in explosive atmospheres, and it replaced Portaria No. 179/2010 from 1 April 2022.
Brazil: rules and approvals
ANATEL's warranty declaration rule rests on Resolution 715/2019, Act 3939/2021 and the Consumer Protection Code, so the local representative takes on legal responsibility for after-sales support.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Brazil. Brazil's classified areas run from offshore pre-salt fields and FPSOs through coastal refining at Paulínia, Suape and Camaçari to inland mining and cane mills. Dust is significant: bagasse and sugar, grain at export terminals, and ore handling. Operators such as Petrobras classify their own areas, and SAMS does not.

Specifying a hazardous area 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 a hazardous area cell phone in Brazil today?
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.
What does a hazardous area cell phone in Brazil cost?
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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
Is the Brazilian Ex certificate tied to the importer?
Under Portaria 115/2022 the manufacturer or the importer can apply to an INMETRO-accredited certification body, and the certificate carries the INMETRO seal. Who holds the certificate and how the factory is audited depend on the model chosen, so confirm the details with an OCP.
Does Brazil accept IECEx or ATEX certificates for hazardous-area equipment?
Not directly. INMETRO requires certification by an accredited OCP under Portaria 115/2022, although an OCP may base its certificate on an IECEx test report and quality report under Model 5. ATEX and IECEx certificates alone do not give market access, so confirm the route with a Brazilian OCP.
Will the interface and paperwork be in Portuguese?
Android 16 runs the interface in Brazilian Portuguese, and Portuguese documentation is part of the launch package. That matters for training records under NR-20 and NR-10, which auditors expect in the working language. Certification is still in progress, so documentation is not yet final. Ask the supplier for sample pages.
