GB/T 2099.5-2008

This standard specifies technical requirements, test methods, and inspection rules for fixed switched socket-outlets with interlock mechanisms used in household and similar environments. It applies to permanently installed electrical accessories that prevent plug insertion or removal when the switch is in the "on" position, ensuring safety in applications like kitchens, workshops, or industrial settings where controlled power disconnection is critical. The standard is used by manufacturers and testing laboratories to verify compliance with Chinese national safety and performance criteria for these specialized socket-outlets.
