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 Mumbai, Maharashtra. A marking check at Mumbai should relate the device to refinery process units, petroleum storage terminals, marine oil handling and nearby chemical plants. Different streams can sit in different gas groups. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, and the operator's classification decides.
