sCOPE
This Standard specifies graphical symbols for mea-suremcnt and control functions in diagrams, with thcsame symbols in simple applications possibly represent-ing instead components or devices implementing suchfunctions. Hor graphical symbols for measurement andcontrol components and devices, see ASME Y14.40.5.
For the fundamentai ruies of creation ard applicationof grapicai symbols in diagrams, see ASME Y14.40.0.
For an overview of the ASME Y14.40 scrics, informa-tion on the creation and use of registration numbers foridentifying graphical symbols used in diagrams,rulesfor the presentation and application of these symbols,and examples of their use and application, see ASMEY14.40.1.

3TERMS AND DEFINITION5
For the purposes of this Standard, the following termsand definitions apply.
3.1
control: purposefui action on or in a syste to meeispecified objectives.
NOTE: Control may include monitoring and safeguarding in addi-tion to the control action itself.
3.2
operatior: trarsfer of mechtartical parts.
EXAMPLE:The closing mcmbcr of a shut-off valve or the contactsof an electromechanical switching device.
NOTES;
(1)The transfer direction may be defined as an opening operation,closing operation. ON-operation.OFF-operation.etc.
(2)The lernt has a specific nueanirng in cortjurntior with elextricmeasuring relays. An over/ under-relay is operating when itscharacteristic quantity reaches the set value by increasing/decreasing in value (itC 60050-448).
3.3
manual control: control of an operation by human inter-vention.
