Poland: background
Poland produced 78 megatonnes of hard coal and 57 megatonnes of brown coal in 2009, and a plan agreed in September 2020 aims to phase out coal by 2049.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for the refinery, fertiliser and gas terminal work where Polish teams actually meet an explosive atmosphere. If you are specifying an IECEx mobile phone for Poland, 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 Poland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Poland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Poland market guide covers.
Poland produced 78 megatonnes of hard coal and 57 megatonnes of brown coal in 2009, and a plan agreed in September 2020 aims to phase out coal by 2049.
Poland's energy sector is the fifth largest in Europe, with an installed electricity capacity of about 61 GW at the end of 2024, so power plants and mines are large sources of classified areas.
In 2020 coal made up 69.5% of national energy production and 68.5% of electricity generation, so coal handling, bunkers and mills create combustible dust zones at many power sites.
PKN Orlen was created in 1999 by merging the state fuel retailer CPN with Petrochemia Płock, the firm running the Płock refineries, and has since grown into a multinational refiner and gas trader.
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 Poland. Poland hosts large national operators and international contractors working inside operating plant fences. IECEx gives foreign partners a common reference alongside ATEX, the main product route here. Ask for the certificate of conformity and its schedule of conditions, which record the marking and conditions of use. The IS-04Z1 has none yet issued.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.

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.
Coal-fired power stations, including large brown coal plants such as Bełchatów, along with coal-using industry, handle bulk fuel that creates dust zones such as Zone 21 and Zone 22. Check that a device's dust group and temperature class match the site classification drawings.
ATEX separates Group I equipment for mining from Group II for surface industries, and underground methane and coal dust conditions differ from surface plant. Check the group marking on any device against the area and the mine operator's own approval procedure.
No. It is designed as Group II surface equipment, and underground coal mining is Group I, with a separate certificate for methane and coal dust. Do not take a Group II device underground. Refineries, fertiliser plants and gas terminals are the intended areas, subject to the site operator's classification.
