Spain: background
REPESA was incorporated in 1948 to build a refinery in the Escombreras valley at Cartagena, so Cartagena is among Spain's oldest refining and chemical locations.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for the refineries, chemical parks and LNG terminals from Bilbao to the Campo de Gibraltar. If you are specifying an intrinsically safe smartphone for Spain, 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 Spain: 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.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Spain. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Spain market guide.
REPESA was incorporated in 1948 to build a refinery in the Escombreras valley at Cartagena, so Cartagena is among Spain's oldest refining and chemical locations.
In 2020 Spain's primary energy came from petroleum (42.3%), natural gas (19.8%), coal (11.6%), nuclear (12%) and renewables (14.3%), so refining, gas and power sites all matter.
Renewables supplied 46.7% of power consumption in 2021 and Spain was the first country to rely on wind as its top energy source for a full year, so wind and solar construction is a large workload.
The Port of Tarragona has doubled its bulk-liquid storage area to 36 hectares, holds over 900,000 cubic metres of storage and serves chemical plants through a common pipeline rack, the Dixquimics Rack, with 71 lines.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Spain. Intrinsic safety suits the long walking routes within the complexes at Tarragona, Huelva and Cartagena and the rounds at regasification terminals. A handheld that limits ignition energy lets operators photograph, record and communicate in the area. The complexes are widely separated, so one configured handset per crew is practical.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.

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.
Cartagena's Escombreras valley is among the oldest refinery locations, and Repsol and other operators run refining and chemical sites on the coasts. Details change, so confirm the current site list and each operator's contractor requirements before planning work.
Gas entry points, regasification plants and compressor stations are likely Zone 1 or Zone 2 areas, so check the device's gas group and temperature class against the site's classification drawings. Operators typically also require device registration and induction, so allow time before a shutdown.
It is designed with IP68 sealing and a rugged build for heat, salt and wash-down. The T4 target is judged against the ambient range on the certificate, which is in progress. Check that range against peak August temperatures at your plant before specifying.
