Ownership has changed
Petrobras has sold some refineries (for example RLAM in Bahia and Reman in Manaus), so procurement rules differ by owner.
The Abreu e Lima refinery in Ipojuca, Pernambuco, is being expanded with a new production line to refine heavy crude from the pre-salt region. Petrobras operates about ten refineries in Brazil, including Replan at Paulinia (415,000 barrels a day), Revap at Sao Jose dos Campos and Reduc at Duque de Caxias, each with classified process, storage and loading areas. If you are specifying an IECEx smartphone for Brazilian refineries, 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 Brazilian refineries: 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 |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |
| Where it applies | Brazilian refineries: Flare and wastewater areas, Refinery process units, Crude and product tank farms | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Brazil Refineries. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Petrobras has sold some refineries (for example RLAM in Bahia and Reman in Manaus), so procurement rules differ by owner.
Refineries sit in the south-east, south, north-east and elsewhere, so logistics differ by site.
Of eight refineries once offered for sale, only two were sold (Mataripe and the Manaus refinery), and Petrobras later resumed investing in the rest of its refining park.
The same plan allocates 2.1 billion dollars to remove logistics bottlenecks, including expanding and optimising terminals and transport infrastructure that serve the refineries.
Revamp projects are under way at the Presidente Bernardes (RPBC), Paulinia (Replan) and Duque de Caxias (Reduc) refineries, with hydroprocessing units planned at Revap and Refap.
Under the Strategic Plan 2024-28+ Petrobras budgets 16.7 billion US dollars across refining, transport and marketing, with 9 billion dollars earmarked for refining, which implies a long pipeline of shutdown and revamp work.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Brazilian refineries. Some refinery projects bring foreign EPCs and licensors into Brazil, where an IECEx certificate of conformity and schedule of conditions are widely understood. Ownership has also changed at some sites, so procurement rules differ. The IS-04Z1 IECEx route is in progress, not complete.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are refinery process units, crude and product tank farms, loading racks and jetties, hydrotreater and hydrogen units. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Refinery contractors typically check Ex certification marking, temperature class and gas group against the area classification, plus local radio approval. The detail varies by site and contractor, so confirm the requirement with the refinery safety group and your contractor induction pack.
Often. During shutdowns and revamps, work shifts between live and isolated units, and permits define which areas are gas-tested. Many sites keep the same Ex requirement for the whole fence line to avoid errors, so confirm with the operator and the turnaround contractor.
Maintenance shutdowns are a natural point, because large contractor workforces enter classified areas, and Reduc has shutdowns scheduled in 2026. Plan MDM enrolment and charging well before mobilisation. Confirm timing and rules with the site operator, as schedules change.
