Kazakhstan: climate and equipment wear
At the offshore Kashagan field, temperatures range from minus 35 to 40 degrees Celsius, with winter sea ice, very shallow water and high hydrogen sulphide levels.
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. This page explains what to look for in an IECEx mobile phone for Kazakhstan, and where the IS-04Z1 stands against that list today.
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.
The main operators, industrial areas and sites that the SAMS Kazakhstan market guide covers.
At the offshore Kashagan field, temperatures range from minus 35 to 40 degrees Celsius, with winter sea ice, very shallow water and high hydrogen sulphide levels.
The Tengiz field in Atyrau Region was discovered in 1979 and covers a licence area of 2,500 square kilometres on the low-lying wetland shore of the Caspian Sea.
Certificates for series production under the regulation can be valid for up to five years and carry the EAC mark together with an Ex marking, so supplier paperwork should show both.
Kashagan was discovered in 2000 in the northern Caspian near Atyrau and holds recoverable reserves of about 13 billion barrels, making it one of the largest discoveries of recent decades.
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 Kazakhstan. Kazakhstan's large fields, such as Tengiz, Kashagan and Karachaganak, work with international consortia and contractors who know IECEx. A certificate of conformity names the equipment, and its schedule of conditions sets conditions of use. IECEx certification for the IS-04Z1 is in progress; EAC Ex follows it.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
The market guide for Kazakhstan covers Tengiz, Atyrau region, Atyrau, Kashagan and Bolashak, North Caspian, Karachaganak, West Kazakhstan, among others. Site-level pages are linked below.
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.
Sites such as Kashagan see temperatures from about minus 35 to 40 degrees Celsius, with winter sea ice, so check the operating temperature range, battery behaviour in cold and heat, and enclosure ingress protection. Confirm site limits with the operator before shipping devices.
High hydrogen sulphide levels at fields such as Kashagan mean sites usually apply strict gas-detection, personal monitor and escape-equipment rules, and may restrict what can be carried into process areas. Ask the operator for its induction requirements and approved portable-device list before arrival.
The IS-04Z1 has IP68 sealing, but cold affects any lithium battery. Ask for the datasheet's operating range and trial a unit on a winter round at a remote site. Site rules on charging and storing devices in safe areas still apply.
