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 Chennai (Manali and Ennore industrial area). A marking check around Manali would read the gas group and temperature class against the unit being visited. Hydrocracker areas can involve hydrogen, which points towards the most demanding gas group, while fuel storage often sits in lower groups. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, subject to certification.
