Example yard
PT Batamec in Tanjung Uncang was founded in 1986, was acquired by PT Teknologi Global Indonesia in March 2024, and occupies a 97-hectare site with a graving dock and slipways.
Batam, in the Riau Islands, has a large cluster of shipyards and offshore fabrication yards, concentrated around Tanjung Uncang on the western side of the island. Batam has five ferry terminals, Harbour Bay, Nongsapura, Sekupang, Waterfront City and Batam Centre, with ferries linking the island to Singapore, Bintan and Johor Bahru in Malaysia. If you are specifying an explosion proof smartphone for Batam shipyards, Riau Islands, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Batam shipyards, Riau Islands: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Batam shipyards, Riau Islands: Vessel tank and cargo spaces, Paint and coating shops, Fuel and gas storage | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Batam Shipyard. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.

Hot, humid equatorial climate with frequent rain.
Batam has a tropical rainforest climate with heavy rainfall all year, so yard equipment faces constant humidity and frequent downpours rather than a dry season.
Two thirds of Batam's population are migrants, and Indonesian is the common working language, with Malay widely understood by visiting contractors from Singapore and Johor.
Shipbuilding and electronics manufacturing are the island's main industries, and proximity to Singapore's ports speeds the movement of goods and spare parts to the yards.
Batam is a free trade zone under a 2007 law with a 70-year term, and BP Batam manages the industrial complex and land, so yard investors deal with that authority as well as national regulators.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Batam shipyards, Riau Islands. In a shipyard, explosion-proof is a broad label. A vessel tank during gas freeing or hot work is a temporary hazardous space, where a handheld needs intrinsic safety rather than a flameproof enclosure. Fixed equipment in fuel stores is a different case. The yard's safety procedure decides which protection concept applies.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Likely candidates are vessel tank and cargo spaces, paint and coating shops, fuel and gas storage, offshore module fabrication areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
They can. Repair and offshore conversion often involve ships that have carried fuel or chemicals, which raises the chance of residual vapours, so gas testing and permit-to-work control are usually stricter. Ask the yard for its tank-entry and hot-work procedures.
Heavy rainfall all year and a tropical rainforest climate mean constant moisture, so devices typically need good ingress protection, sealed charging contacts and regular drying and cleaning. Check the rating and charging method against the yard's safety rules.
Not always, but during painting, tank cleaning, gas freeing or hot work the space is usually treated as hazardous. The yard's gas-free procedure and permit decide. Do not take a non-Ex device into such a space unless the permit explicitly allows it.
