The organisation · Sinopec
Working with China Petroleum & Chemical Corporation (Sinopec): sites and classified areas
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
Sites and areas
- Zhenhai refinery and petrochemical base (Ningbo)
- Maoming refining and chemical company
- Shengli Oilfield (Shandong)
Classified areas
- Refinery process units
- Petrochemical plants
- Oil and gas production facilities
Supplier approval · Sinopec
How suppliers reach Sinopec
Sinopec buys largely through its own EPEC.com procurement portal, and only suppliers certified by Sinopec can sell on it; confirm current certification steps with Sinopec. 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 Sinopec that matters for portable equipment
Sinopec: who works there
Sinopec Group is a Beijing-based state-owned enterprise, administered by SASAC for the State Council.
Sinopec: industry on the ground
The Jiujiang Petrochemical Complex was first built in 1975, has been upgraded repeatedly and processes about 8 million tonnes of crude oil a year, so old and modern plant sit together on one site.
Sinopec: projects and investment
A joint-venture ethylene plant in Wuhan was completed at the end of 2012 with a South Korean partner, designed to provide about 800,000 tonnes a year of ethylene.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 Sinopec. Large refinery and petrochemical sites such as Zhenhai in Ningbo involve long inspection routes and turnaround campaigns with photographing, tag reading and permits. A handheld designed as intrinsically safe could carry that on one device. The IS-04Z1 is designed for this use, though certification is still in progress.
The route · supply
Sourcing the IS-04Z1 for Sinopec
Supply of the IS-04Z1 to Sinopec starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · Sinopec
Frequently asked questions
Can Sinopec 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 intrinsically safe smartphone for Sinopec 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
How does Sinopec approve suppliers?
Sinopec buys largely through its own EPEC.com procurement portal, and only suppliers certified by Sinopec can sell on it; confirm current certification steps with Sinopec.
How will SAMS supply Sinopec?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do chemical industry parks such as Shanghai add extra rules for contractors?
Large chemical industry parks usually apply park-wide safety rules, access control and contractor induction on top of each plant's own permit system. Check with both the plant operator and the park management what training and equipment approvals are needed before bringing devices on site.
How does coastal humidity in eastern China affect phone selection?
Eastern coastal plants are often hot and humid in summer with salt-laden air near the coast, which stresses seals, connectors and batteries. Look for good ingress protection and corrosion resistance, and ask the plant about its environmental limits for portable electronics.
Can a supplier sell a handset to Sinopec through EPEC.com?
Only suppliers certified by Sinopec can sell on its EPEC.com portal, so certification comes first. Confirm the current steps with Sinopec. The IS-04Z1 has no certificate yet and SAMS has appointed no distributor, so no sales route is open. A datasheet and schedule can be shared now.
