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.

WhereKazakhstan
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.
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.

Field notes · Kazakhstan
More about Kazakhstan that matters for portable equipment
Kazakhstan: industry on the ground
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.
Kazakhstan: rules and approvals
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.
Kazakhstan: background
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.
The term · IECEx
What “IECEx” means for a smartphone
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.

Specifying an IECEx smartphone for Kazakhstan
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Kazakhstan
Frequently asked questions
Can we buy an IECEx smartphone in Kazakhstan today?
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.
What does an IECEx smartphone in Kazakhstan cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which sites in Kazakhstan does this cover?
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.
Is intrinsically safe the same as explosion proof?
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.
What climate range should devices cope with at Caspian sites?
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.
Why is hydrogen sulphide relevant to phone selection in Kazakh fields?
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.
Can a handset cope with steppe winters?
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.
