CNPC: projects and investment
In July 2013 CNPC and Eni signed a 4.2 billion dollar deal for a 20% stake in an offshore natural gas block in Mozambique, an example of its overseas gas investments.

IECEx Mobile Phone for CNPC
In March 2014 the chairman announced that six business units would be opened to private investors, which means some service and equipment purchasing may sit with newer mixed-ownership entities. Its Changqing field in the Ordos Basin is reported as China's largest oil and gas field. This page explains what to look for in an IECEx mobile phone for CNPC, and where the IS-04Z1 stands against that list today.

Supplier approval · CNPC
Becoming an approved supplier to CNPC
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.
Field notes · CNPC
More about CNPC that matters for portable equipment
CNPC: who works there
Its subsidiary Great Wall Drilling Company provides drilling services, so rig crews and service contractors are an important group of hazardous-area users within the CNPC family.
CNPC: infrastructure
In 2018 the company announced gas storage facilities with a total capacity of 55.6 billion cubic metres in northern Henan province, to ease winter supply bottlenecks, adding underground storage and compression sites.
CNPC: projects and investment
CNPC reports around 30 international exploration and production projects, with operations in countries such as Azerbaijan, Canada, Indonesia, Oman, Peru and Thailand, so some staff work under foreign site rules.
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 CNPC. CNPC operates in China and overseas, so international contractors and joint-venture partners are part of its supply chain, and many use IECEx documents. A certificate of conformity with its schedule of conditions gives them and CNPC reviewers a shared reference. The IS-04Z1 is designed for IECEx, still in progress. Chinese rules may apply separately.

Specifying an IECEx mobile phone for CNPC
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 · CNPC
Frequently asked questions
Can CNPC buy the IS-04Z1 today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an IECEx mobile phone for CNPC 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 CNPC 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.
How do northern Chinese oilfields affect device choice?
Fields in northern and north-western China can see very cold winters and dusty, dry summers, so battery performance in cold, dust ingress protection and screen visibility in glare matter. Ask the oilfield for its operating temperature limits and any site restrictions on portable electronics.
What explosion-protection certificate do Chinese sites normally require?
China has its own explosion-protection certification scheme and marking, and operators usually expect equipment to carry the Chinese certificate in addition to any international ones. Confirm with the site and its certification body which approvals they accept before offering handheld devices.
Is a handset suited to wide inland fields like Changqing?
It can be, if the marking matches the area classification, battery capacity covers long shifts and the fleet can be managed centrally. Dust and winter cold need checking. IP68 is not explosion protection. The IS-04Z1 is not yet certified, so confirm with the site operator.
