T/CEEIA 268-2017 Explosion-proof safety device for equipment used in explosive environments

Scope

Scope: This standard specifies the requirements for electrical safety devices that eliminate ignition sources for equipment used in explosive environments. This standard also applies to safety devices installed in safe areas to protect equipment used in explosive environments. Note 1: This standard also applies to the design and evaluation of safety devices for protection systems. The safety of electrical equipment used in explosive environments relies on the correct operation of safety devices within a specific range. For example: control devices and motor safety devices (used for temperature monitoring) for positive pressure equipment. Control or monitoring devices can be used to eliminate ignition sources. Therefore, these devices should implement appropriate measures within a proper response time, such as issuing warnings or automatic shutdown. Note 2: Some ignition sources cannot be protected by safety devices, such as static electricity and mechanical sparks caused by impact. Some explosion-proof measures are not necessary.
