TERM AND DEFINITIOr
For the purposes of this Standard. the following termand definition apply.
3.7
symhol: visually perceptible figure used to transmitinformation independently of language.
NOTE: It may be produced by drawing.printing，or other means.
4GENERAL
4.1
Symbols shall be as shown in succeeding clauses ofthisStandard. However. symbols that are shown inoutline form may. in actual use. be filled for enhancedclarity of reproduction and improved visual perception by the operator, except as otherwisc noted for individualsymbols.
4.2
Limitations inherent in some reproduction and dispiaytechnologies may require increased line thickness orother minor modifications of symbols. Such modifica-tions are acceptabie. proviciedi the symboi remains un-changedi in its basicgraphical elenents ani easilydiscernible by the operator.
4.3
Additionally. to improve the appearance and percepti-bility of a graphical symbol. or to coordinale with thedesign of the equipment to which the symbol is applied.it may be necessary to change the line thickness orround the corners of a symboi. The grapiic designeris nonmally fiee to make sucl chamges,provided thatthe esscntial perceptual characteristics of the symbolare maintained. See ISO 3461-1: 1988,subclause 10.2.
4.4
For actuai use. aii symbois shaii be reproduced largeenough to be easily discernible by the operator. SeeIso 3461-1 for guidelines on the proper sizing ofsynbois. Synbois shaii be used in tie orientation shuwnin this Standard unless otiaer wise noted for individualsymbols.
4.5
Most symbols are constructed using a building blockapproach in which various symbols and symboi elementsare cormbined in a logical manner to produce newsymbols.
4.6
lf a symbol shows a machine or parts of a machinefrom a side view. a machine moving from right to leftacross the symbol grid area shall be assumed. If asymbol shows a inachine or parts of a machine from an overhead view，a machine moving from bottom totop across the symbol grid area shall be assumed.
4.7
Syubols on controls and displays shall have a goodcontrast to their background. A light symbol on a darkbackground is prefered foruost controis. Dispiaysmay usc either a light symbol on a dark backgroundor a dark symbol on a light background，dependingupon which altcrnative provides the best visual percep-tion. When a symbol imagc if reverscd (for example,from black-on-white to whitc-on-black and vice versa),it shall be done for the entire symbol.
4.8
Synbuis shaii be located on or adjacent to the controlor display that is being identified. Where more thanone symboi is required for a control, the symbols shallbe located in relation to the controi such that movementof thc control toward the symbol shall affect the functiondepicted by that symbol.
4.9
Arrows used in symbols shall conform to the require-ments of ISO 4196. 1SO 346l-l shall he. consultedfor the general principles of creating symbols.
