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 Surabaya and the Gresik industrial area. A marking check around Surabaya would separate gas areas, such as port fuel and chemical plants, from dust areas, such as the cement plant, listed as Zone 21 in the sheet. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, is gas only and unapproved.

Questions · Surabaya
Frequently asked questions
Can we buy an Ex-proof mobile phone in Surabaya today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof mobile phone in Surabaya 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 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 Surabaya and the Gresik industrial area would use it?
Likely candidates are port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas, industrial estate chemical plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Surabaya and the Gresik industrial area?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Surabaya and the Gresik industrial area.
Is the climate in Surabaya hard on handheld equipment?
Temperatures are steady, around 23 to 31 degrees, but the wet season from October to May brings heavy rain and humidity, and coastal air adds salt. Devices typically need good ingress protection and cleaning routines for exposed use.
Which industrial areas around Surabaya matter for hazardous-area equipment?
The wider metropolitan area includes Gresik, Sidoarjo and other satellite cities with port-side and industrial plants. Typical hazards include fuel, chemical and bulk handling, so ask each operator for its zone classification and device approval requirements.
Does Gresik count as part of the Surabaya market?
Yes in practice. Gresik lies about 25 kilometres north-west of Surabaya, and its fertiliser and cement works are major buyers of safety equipment. Requirements are set plant by plant. Confirm with each site operator's safety function.
