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 a hazardous area 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.
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.

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.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Spain. Spanish classified areas are dense, widely separated islands: the Repsol complexes, Moeve at Huelva and Campo de Gibraltar, BP at Castellón, the Tarragona chemical belt and a large network of regasification terminals. Each operator classifies its own areas. SAMS does not classify any area and designs only for a stated one.
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.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.

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.
