Refinery cluster
Replan alone accounts for about 20 per cent of Brazil's refining; Revap is 252,000, RPBC 170,000 and Recap 53,000 barrels a day.
Sao Paulo is Brazil's largest city and an industrial state. The city itself is not a refinery site, but the state hosts four Petrobras refineries: Replan at Paulinia (415,000 barrels a day), Revap, RPBC at Cubatao and Recap at Capuava. If you are specifying an ATEX and IECEx mobile phone for Sao Paulo state, 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 Sao Paulo state: 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | Sao Paulo state: Refinery process units, Tank farms, Pipeline terminals | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in São Paulo. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Replan alone accounts for about 20 per cent of Brazil's refining; Revap is 252,000, RPBC 170,000 and Recap 53,000 barrels a day.
Sites are connected by an extensive road network, which helps delivery and service.
Replan at Paulinia, in Sao Paulo state, is Petrobras' largest refinery at 434,000 b/d, and the 2024-28 plan includes new units and upgrades there.
Petrobras plans revamps at the Presidente Bernardes refinery and Replan, an aviation bio-kerosene plant at RPBC and a combustion boiler at the Capuava refinery, all in Sao Paulo state.
Sao Paulo is Latin America's largest urban economy, representing around 10 percent of Brazil's GDP, and is home to the B3 stock exchange, so many contractors and procurement teams are based there.
São Paulo has a humid subtropical climate, and heavy storms can bring more than 140 mm of rain in 24 hours, so outdoor and plant-yard work needs weather protection for portable equipment.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Sao Paulo state. Sao Paulo state hosts Petrobras refineries at Paulinia, Cubatao and Capuava, plus Revap, so reviewers at those plants will want evidence that fits Brazil's Inmetro-accredited route. A dual ATEX and IECEx route is designed to help international contractors. The IS-04Z1 has no certificate yet.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are refinery process units, tank farms, pipeline terminals, fuel storage and loading. 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.
Imports usually clear through Santos and travel by highway, but customs and radio approval can add time, so allow a margin. Confirm clearance steps with a local agent early in the project.
Typically a gate induction, a permit system and equipment checks at one of Brazil's largest refineries. Confirm with the contractor which zones you will enter and whether your devices need Ex certification and local radio approval.
Not by assumption. Each plant has its own classification and procedures, and purchasing is usually through registered-supplier processes. Ask each operator for its Ex equipment policy and obtain the area classification for the specific unit before ordering.
