Sao Paulo is Brazil's largest city and an industrial 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. If you are specifying an explosion proof smartphone 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.
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.
| 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 | 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.

Sites are connected by an extensive road network, which helps delivery and service.
Many industrial buyers and distributors keep offices in the city, while the plants are in other municipalities.
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.
Replan serves the interior of Sao Paulo state (about 55 percent of its output) and parts of Mato Grosso, Mato Grosso do Sul, Rondonia, Acre and southern Minas Gerais.
The Port of Santos is 79 km from Sao Paulo city and is reached by the Anchieta and Imigrantes highways, which carry most import and export freight for the region.
Replan started operating in 1972 on about 9.1 km2, with capacity of 66,000 m3/d, and makes gasoline, diesel, LPG, aviation kerosene, asphalt, petrochemical naphtha and propane.
“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 Sao Paulo state. The city itself is not a refinery site, so explosion-proof applies at state refineries: process units, tank farms, pipeline terminals and fuel storage and loading. Fixed gear may be flameproof Ex d, while a portable handset relies on intrinsic safety. The IS-04Z1 is designed for that, pending certification.
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.
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.
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.
