KazMunayGas: who works there
Two noted producing fields operated within the group are Uzenmunaigas and Embamunaigas, both in western Kazakhstan, which gives a practical picture of where field-level contractor work is concentrated.

IECEx Smartphone for KazMunayGas
Its upstream arms include KazMunaiGas Exploration Production for onshore fields and KazMunayTeniz for offshore oil and gas, so site rules can differ between the land and Caspian offshore businesses. It has upstream, transport and refining interests, including the Atyrau and Pavlodar refineries, a 50% stake in the Shymkent refinery and a 20% stake in Tengizchevroil. This page explains what to look for in an IECEx smartphone for KazMunayGas, and where the IS-04Z1 stands against that list today.

WhereKazMunayGas
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for KazMunayGas: 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Supplier approval · KazMunayGas
Supplier registration at KazMunayGas
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

More about KazMunayGas that matters for portable equipment
KazMunayGas: infrastructure
KazTransGas handles gas transportation inside the group, which means compressor stations and gas pipeline sites form a separate hazardous-area workforce from the oilfield and refinery operations.
KazMunayGas: logistics and access
In January 2023 the company signed a strategic partnership with Abu Dhabi Ports Company on marine fleet and coastal infrastructure in the Caspian and Black Seas, pointing to growing port and vessel activity.
KazMunayGas: background
KazMunayGas was created by presidential decree in February 2002 by merging Kazakhoil and Oil & Gas Transportation, so it combines upstream production with pipeline and transport operations in one national group.
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 KazMunayGas. KazMunayGas has a joint-venture refinery and interests alongside international partners, so international contractors and licensors often arrive with IECEx documents. Reviewers there would look for a certificate of conformity with its schedule of conditions. IECEx is a target for the IS-04Z1 and is in progress, so treat it as a planned route and not a held approval.

- 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.

Questions · KazMunayGas
Frequently asked questions
Can KazMunayGas buy the IS-04Z1 today?
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.
What does an IECEx smartphone for KazMunayGas cost?
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.
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.
How does KazMunayGas approve suppliers?
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
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.
Does a partnership with Tengizchevroil change what equipment buyers should expect?
Tengizchevroil is a joint venture with international partners, so its contractors usually work to its own standards and induction process rather than to KazMunayGas rules alone. Treat the joint venture and the national company as separate customers and check each one's approved equipment requirements.
Is the Atyrau refinery a likely place for Zone 1 handheld devices?
Refineries typically contain Zone 1 and Zone 2 gas areas around process units, loading and tank farms. Because a large modernisation programme added new units, area classification may have changed. Confirm the current zoning and permit-to-work practice with refinery HSE before deploying phones.
How do Kazakh winters affect a handheld phone?
Very cold weather reduces battery capacity and can slow screens, while snow and dust are handled by IP68 sealing, which is not an explosion rating. Test the device at the lowest temperatures on your sites, keep spares warm and charge in safe areas. Check the operating range on the datasheet.
