Kazakhstan: rules and approvals
Kazakhstan applies TR CU 012/2011, the Eurasian Economic Union technical regulation, to equipment for explosive atmospheres; certification is mandatory and self-declaration is not allowed.
A Zone 1 / Zone 21 smartphone for crews at Tengiz, Kashagan and Karachaganak, the Atyrau, Pavlodar and Shymkent refineries and the coal and metals industry of Karaganda and Ekibastuz. If you are specifying an Ex-proof mobile phone for Kazakhstan, 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 Kazakhstan: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Kazakhstan: Tengiz, Atyrau region, Atyrau, Kashagan and Bolashak, North Caspian | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Kazakhstan. 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 Kazakhstan market guide.
Kazakhstan applies TR CU 012/2011, the Eurasian Economic Union technical regulation, to equipment for explosive atmospheres; certification is mandatory and self-declaration is not allowed.
Atyrau, 350 kilometres north of Tengiz, is the main transport hub for Tengiz oil, so road, rail and air links through Atyrau shape logistics for the western fields.
Under TR CU 012/2011 the applicant must be registered in a member state, testing is done by bodies in the union's unified register, and ATEX or IECEx certificates are not accepted in place of it.
Telecommunications matters, including radio-frequency conversion procedures, are handled by the Telecommunications Committee within the ministry responsible for digital development.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Kazakhstan. A Kazakh marking check would compare gas group, dust capability, category and temperature class with the zone plan. Sour gas plants, refineries and coal sites, which add dust, can differ. The IS-04Z1 marking target is II 2 G Ex ib IIC T4; it remains a target, and EAC Ex is still to come.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.

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.
Equipment for explosive atmospheres falls under the Eurasian Economic Union regulation TR CU 012/2011, where certification is mandatory, self-declaration is not accepted and ATEX or IECEx certificates do not replace it. The applicant must be registered in a member state. Confirm requirements with an accredited EAEU certification body.
Telecommunications matters, including radio-frequency procedures, are handled by the Telecommunications Committee under the ministry responsible for digital development. Whether a specific phone needs notification or registration depends on its radio technologies, so check current requirements with the committee or a local representative before importing.
The market guide says EAC Ex certification under TR CU 012/2011 is required and planned after IECEx. It has not been granted. Ask the operator which approvals it needs, and check the current certification status before placing any order.
