IEC 61812-1:2011 applies to time relays for industrial applications (e.g. control, automation, signal and industrial equipment). It also applies to time relays for automatic electrical controls for use in, on, or in association with equipment for residential and similar use. This edition includes the following significant technical changes with respect to the previous edition: - addition of terms and definitions more commonly used by industry; - addition of timing charts to help explain terms and definitions involving a sequence of events; - addition of provisions for residential use.
