More about Rio de Janeiro that matters for portable equipment
Rio de Janeiro: who works there
Petrobras has its headquarters in downtown Rio de Janeiro, which is why many supplier registrations, tender offices and engineering teams for the whole Brazilian oil sector are in the city.
Rio de Janeiro: projects and investment
Petrobras' refining plan includes the Boaventura Energy Complex in Rio de Janeiro state and a revamp of the Duque de Caxias refinery, so project activity remains close to the city.
Rio de Janeiro: background
Petrobras was created in 1953; its Reduc refinery started up near Rio in 1961 and its Cenpes research centre was founded in 1963, giving the city a long record in refining and technology.
Rio de Janeiro: geography and layout
The 2007 and 2008 Santos Basin pre-salt discoveries (Tupi, Jupiter and Sugar Loaf) lie about 300 km off the coast of Rio de Janeiro, tying the city to deepwater supply and service work.
The term · IECEx
What “IECEx” means for a smartphone
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 Rio de Janeiro. With decision-making and many service companies concentrated in downtown Rio, international contractors visit headquarters before going to plants. IECEx, with a certificate of conformity and schedule of conditions, is a common language for them. The IS-04Z1 IECEx route is in progress.

Questions · Rio de Janeiro
Frequently asked questions
Can we buy an IECEx smartphone in Rio de Janeiro 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 an IECEx smartphone in Rio de Janeiro 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Rio de Janeiro would use it?
Likely candidates are refinery process units (duque de caxias), shipyards and fpso yards, tank terminals, offshore support bases. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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 Rio humidity a concern for stored equipment?
Rio's coastal setting is warm and humid, so spare devices are best kept in dry cases with desiccant and checked for condensation before use. Confirm storage guidance in the warehouse or base procedures.
Does the city of Rio itself contain hazardous areas?
Mostly in the port, fuel terminals and refining sites around Guanabara Bay rather than in the central city. Check the exact location with the project, because zones are set by each facility's classification study.
Which nearby sites might a Rio-based team visit?
Reduc at Duque de Caxias, about 17 km from downtown, Guanabara Bay shipyards such as Brasa at Niteroi, Angra dos Reis and Itaborai. Each has its own classification and rules. Confirm approvals and documentation requirements with the site operator.
