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. If you are specifying an intrinsically safe cell 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.
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 classified areas, operators and sites below are the ones covered in the SAMS Kazakhstan market guide.
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.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Kazakhstan. Crews at Tengiz, Kashagan and Karachaganak work across large plants and long distances, and a replacement is far away. An intrinsically safe handheld lets operators record readings and photograph issues at the point of work. That is the design intent, pending certification and operator approval.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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 circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
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.
