IEC 62744:2014 provides generic rules for the representation of states of objects by graphical symbols standardized in IEC 60617, ISO 14617, IEC 60417, for example, and for future graphical symbols included in these standards. It also provides operational states of an object as examples that typically occur and which need to be represented by standardized graphical symbols and defines generic rules to be applied. It specifies which types of presentation facilities are recommended to present the different operational states to humans.
