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.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Brazil: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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 · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Brazil. An offshore rotation in the Santos Basin or Campos Basin is measured in weeks, and a broken handset waits for the next boat. An intrinsically safe handheld is designed for that pattern, with a 4,000 mAh battery, platform Wi-Fi and Bluetooth pairing to gas detection, so inspection rounds continue without a replacement.

Specifying an intrinsically safe mobile 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 intrinsically safe mobile 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 intrinsically safe mobile 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 does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
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.
