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 Visakhapatnam (Vizag), Andhra Pradesh. Checking a marking at Visakh would mean reading the zone assigned to a process unit, tank farm or berth, then matching gas group and temperature class. Crude and product vapours are typically in the IIA or IIB groups, so IIC is conservative. The target marking is II 2 G Ex ib IIC T4, unapproved.

Questions · Visakhapatnam India
Frequently asked questions
Can we buy an Ex-proof mobile phone in Visakhapatnam India 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 Visakhapatnam India 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 Visakhapatnam (Vizag), Andhra Pradesh would use it?
Likely candidates are refinery process units, crude and product tank farms, underground strategic crude storage, port petroleum berths and single point mooring. 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 Visakhapatnam (Vizag), Andhra Pradesh?
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 Visakhapatnam (Vizag), Andhra Pradesh.
Does monsoon weather affect handheld equipment used outdoors at Vizag?
Yes. Rainfall of roughly 1,100 mm a year, mostly in the monsoons, plus coastal humidity and salt air, mean outdoor users usually want good ingress protection, sealed ports and regular cleaning of connectors. Check the rating against your site specification.
Which hazardous-area industries are concentrated in Visakhapatnam?
The main clusters are the HPCL Visakh refinery, the port with its bulk cargo handling, the steel plant and its coal and ore supply chain, and the shipyards. Gas, vapour and combustible dust zones all arise, so confirm the classification with each site.
Can a contractor bring any new handset into the Visakh refinery?
Not by default. Entry of electronic devices is governed by the operator's permit and equipment approval rules, which contractors must follow. A device in certification would normally need operator acceptance first. Confirm with the site operator's HSE team before planning any trial.
