Supplier approval · CNPC
How suppliers reach 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.

More about CNPC that matters for portable equipment
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.
CNPC: background
CNPC originated as a government department after 1949, when a Fuel Industry Ministry was formed, and the group was restructured in 1998 along upstream and downstream lines.
CNPC: who works there
CNPC is the government-owned parent of listed PetroChina, created in 1999, which holds most of the group's exploration, refining, marketing, chemicals and natural gas businesses, so site buyers are often PetroChina units.
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.

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 smartphone for CNPC cost?
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.
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.
How will SAMS supply CNPC?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What language is expected on documentation for Chinese sites?
Chinese is the working language, so labelling, safety instructions and training for hazardous-area devices are normally expected in Chinese, with English accepted for some engineering discussion. Confirm the documentation language with the site's procurement and safety departments.
Is CNPC or PetroChina the right contact for supplying Ex phones?
PetroChina holds most of the operating assets, including refining, chemicals and gas, while CNPC is the parent group with other businesses such as drilling services. The right contact depends on the site, so ask the local oilfield or refinery safety and procurement teams which entity places the order.
Does CNPC accept IECEx documents for equipment approval?
CNPC runs its own supplier registration and equipment approval, so the answer depends on its current requirements and any national rules. IECEx documents help comparison. The IS-04Z1 has no certificate yet. Confirm requirements with CNPC's procurement and HSE teams before planning an evaluation.
