The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Pekanbaru and the Rokan block, Riau. A marking check on the Rokan block would compare a label with zones at gathering stations, treatment and storage. Crude and associated gas vapours are typically IIA or IIB, so IIC is conservative. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not approved.

Questions · Pekanbaru Oil Field
Frequently asked questions
Can we buy an Ex-proof mobile phone in Pekanbaru Oil Field 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 Ex-proof mobile phone in Pekanbaru Oil Field 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Pekanbaru and the Rokan block, Riau would use it?
Likely candidates are gathering stations, wellheads and flowlines, oil treatment and storage, steam generation and power facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Why does steamflood production matter for equipment used at Duri?
Steamflood means hot steam lines and wells operate close to oil and gas handling, so surface temperatures can be higher than at conventional wells. Handheld devices should respect the site's temperature limits and classification, so ask the operator for its rules on portable electronics.
Which company operates the large oil fields around Pekanbaru today?
The Rokan block, including the Minas and Duri fields, has been run by Pertamina Hulu Rokan since August 2021. Contractors and suppliers typically register through Pertamina's vendor processes and follow the site's own induction and permit rules, so confirm current requirements.
Who approves suppliers for the Rokan block?
Suppliers are normally approved by the operator and its contractors, following Pertamina group processes since the 2021 operator change. Ask PT Pertamina Hulu Rokan about current registration requirements before offering any equipment. Confirm with the site operator.
