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.
The IS-04Z1 is an Ex mobile phone for people working inside classified areas on Brazilian platforms, refineries, petrochemical units, mills and terminals. If you are specifying an explosion proof cell phone for Brazil, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Brazil: Santos Basin pre-salt, Campos Basin, Duque de Caxias | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Brazil. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

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.
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.
“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.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
The market guide for Brazil covers Santos Basin pre-salt, Campos Basin, Duque de Caxias, Paulínia, among others. Site-level pages are linked below.
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.
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.
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.
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.
