3767-1:2016(E) 3.1 symbol graphical symbol visually perceptible figure used to transmit in formation independent o f language Note to entry: It may be produced by drawing, printing or other means Letters, numerals and mathematical symbols may be used as symbols or symbol elements For some specific applications, groups o f letters (for example, AUTO, STOP) are used as symbols or symbol elements Note to entry: Letters and numerals are not registered by ISO/TC 145/SC or published in ISO 7000 unless they are symbol elements embedded in graphical symbols 3.2 icon digital display icon digitized (pixelated) representation o f a graphical symbol, usually used on a reconfigurable electronic display screen or graphical user inter face (GUI) Note to entry: A single symbol can be represented by multiple icons, each o f a di fferent size, pixel count or colorization 4.1 General Except where indicated in subsequent clauses, symbols shall be used as shown in this document 4.2 Selected symbols, which are shown in outline form in this document, may be filled in actual use for enhanced clarity o f reproduction and improved visual perception by the operator, except as otherwise specified for individual symbols, and in accordance with IEC 80416-3 Limitations inherent in some reproduction and display technologies can require increased line width or other minor modifications o f symbols Such modifications are allowed, provided that the symbol remains conceptually unchanged in its basic graphical elements and is easily discernible by the operator 4.3 4.4 To improve the appearance and perceptibility o f a graphical symbol, or to coordinate with the design o f the equipment to which it is applied, it can be necessary to modi fy the symbol as indicated in IEC 80416-3 (for example, to change the line width or to round the corners o f the symbol) Such modifications are allowed, provided that the essential perceptible characteristics o f the symbol are maintained 4.5 For actual use, all symbols shall be reproduced large enough to be easily discernible by the operator Follow IEC 80416-1 for the proper sizing o f symbols Symbols grouped together in a display or on a set o f controls should be scaled to the same degree relative to the corner marks o f the symbol original as shown in this document in order to maintain the correct visual relationship among the symbols Symbols shall be used in the orientation shown in this document, unless rotation or mirror imaging is specifically allowed for individual symbols Most symbols are constructed using a building block approach in which various symbols and symbol elements are combined in a logical manner to produce a new symbol 4.6 In some cases, symbols may be used in conjunction, without being combined into a composite symbol, to convey the same meaning as the composite symbol 4.7 4.8 Symbols are generally intended to replace a word or words with a graphical image that has the same meaning for all operators, regardless of their native language However, the use of a graphical symbol to identi fy a control or display does not preclude the use o f words in conjunction with that control or display © ISO 2016 – All rights reserved ISO 3767-1:2016(E) I f a symbol shows a machine or parts o f a machine from a side view, a machine moving from right to le ft across the symbol area shall be assumed I f a symbol shows a machine or parts o f a machine from an overhead view, a machine moving from bottom to top across the symbol area shall be assumed 4.9 Symbols on controls and displays shall have a good contrast to their background A white or lightcoloured symbol on a black or dark-coloured background is pre ferred for most controls Displays may use either a white or light-coloured symbol on a black or dark-coloured background or a black or darkcoloured symbol on a white or light-coloured background, depending upon which alternative provides the best visual perception When a symbol image is reversed (for example, from black-on-white to whiteon-black or vice versa) this reversal shall be done for the entire symbol 4.10 4.11 I f symbols are cast, moulded, embossed or stamped into a surface, the symbols shall be visually distinct from that surface without dependence on colour Symbols shall be located on or adjacent to the control or display that is being identified Where more than one symbol is required for a control, the symbols shall be located in relation to the control such that movement o f the control towards the symbols shall e ffect the function depicted by that symbol 4.12 4.13 Arrows used in symbols shall form to the requirements o f ISO 80416-2 IEC 80416-1 shall be consulted for the general principles for creating symbol originals IEC 80416-3 should be consulted for guidelines for the application o f symbols 4.14 ISO/IEC registration numbers are shown for symbols which are registered in ISO 7000 or IEC 60417 NOTE Symbol originals are approved and registered either by ISO/TC 145/SC and published in ISO 7000 or by IEC/SC 3C and published in IEC 60417 In some cases, modified or application symbols, rather than the registered symbol originals, are standardized in this document 4.15 When letters or numerals are used in a symbol, the font shown shall not be considered definitive Other fonts may be used so long as the letters and numerals remain legible 4.16 Symbols in this document are shown within marks that delimit the corners o f the 75 mm square basic pattern from IEC 80416-1 Corner marks are not part o f the symbol, but are provided to ensure consistent presentation o f all symbol graphics 5.1 Colour When used on illuminated displays, the following colours shall have the meanings indicated: — red denotes a failure, serious malfunction or operating condition that requires immediate attention; — yellow or amber denotes a condition outside normal operating limits; — green denotes a normal operating condition 5.2 In addition, certain colours shall be used for specific applications: — blue is used for the high beam, upper beam display (see 15.1); — red is used for the hazard warning display and for the hazard warning control (see 15.6); — green is used for the turn signal display (see 15.10) 5.3 I f colour is used on or in association with symbols for heating and cooling systems, the colour red shall be used to indicate hot and the colour blue shall be used to indicate cold © ISO 2016 – All rights reserved ISO 3767-1:2016(E) Development of new symbols 6.1 Prior to developing a new symbol, a search should be conducted for previously standardized symbols with the same or similar meaning to what is needed ISO 7000 and IEC 60417 (both available in database form) are compilations o f internationally standardized symbols which can be use ful both for finding appropriate symbols that not appear in ISO 3767 and for generating concepts that can be used in the development o f new symbols New symbols shall be developed in accordance with the principles o f Annex A of this document IEC 80416-1 should be consulted for general principles for the creation o f symbols Arrows shall be in 6.2 accordance with ISO 80416-2 Different arrow forms have different meanings according to ISO 80416-2 Care should be taken to use the correct arrow form Following the guidelines of Annex A of this document makes possible the development o f symbols appropriate in graphical form and content for international standardization and ISO 7000 registration Symbols proposed for standardization in this document shall include a short explanation o f the unction or expected use o f the symbol 6.3 f NOTE IEC 80416-1 uses the term “description” for this type o f in formation and provides guidelines for writing descriptions for symbols intended for standardization in ISO 7000 or IEC 60417 The descriptions for symbols standardized in this document can serve as examples Adaptation of symbols as digital display icons Symbols can be adapted for use as digital display icons on visual display units, reconfigurable displays or other electronic displays Such adaptations should follow the principles o f ISO 80416-4 Special care should be taken to ensure that digital display icons preserve the visual impression o f the symbol from which the icon is adapted The same principles regarding use o f colour with symbols apply to the use o f colour with digital display icons Base symbols No 8.1 Graphical symbol ISO/IEC registration number Symbol title and description O i l ; f l u i d To indicate oil or other

provides guidelines for the development and evaluation o f graphical symbols intended for inclusion in ISO 3767 and for registration in ISO 7000 The guidelines are necessarily flexible, because it is impossible to anticipate all potential graphical limitations in their application However, following these guidelines is expected to result in graphical symbols that satis fy the requirements o f IEC 80416-1 and ISO 80416-2 and thereby quali fy for potential standardization and registration in ISO 7000 A.2 Basic principles A.2.1 Symbols should be as simple, clear, distinct and logical as possible to enhance recognition and reproduction A.2.2 Symbols should incorporate base symbol elements which can be used alone or combined as necessary into a logical graphical arrangement to form a symbolic language which, i f not immediately obvious, can at least be learned A.2.3 Graphical clarity should prevail when graphical limitations conflict with logical consistency, because no graphical symbol is recognizable, no matter how logical it might be, i f the symbol cannot be distinguished from other graphical symbols or i f the individual symbol elements cannot be distinguished from each other A minimum o f detail should be included in individual graphical elements and composite symbols Only details which enhance recognition should be included, even i f other details are accurate renditions A.2.4 of the machine or component The key consideration is the essential message that the graphical symbol is trying to convey It is critically important to know what happens when a control is activated, but o ften o f little or no importance A.2.5 to know how the functional result is achieved A.3 Fundamental symbol elements A.3.1 General Symbol elements can be divided into a number o f fundamental types, including those described in this clause A.3.2 Operational system symbols Symbol elements representing operational systems (for example: engines, transmissions, hydraulics, brakes) or functional equipment (for example: dozer blades, loader buckets, grapples) A.3.3 Vital fluid symbols Symbol elements representing vital machine fluids (for example: oil, fuel, coolant, air) © ISO 2016 – All rights reserved 85 ISO 3767-1:2016(E) A.3.4 Functional condition or operational status symbols Symb ol elements repre s enti ng the s tatu s o f vita l fluid s (for example: pre s s u re, temp eratu re, level) or the fu nc tiona l cond ition o f op erationa l s ys tem (for e xa mple: lo ck, u n lo ck, ma l fu nc tion) A.3.5 Movement or location symbols A.3.5.1 Symb o l elements rep res enting s p atial movement, s ettings o r lo catio n o f machines , p arts o r A.3.5.2 Symb o l elements rep res enting ro tatio nal movement o f machine p arts o r co mp o nents components (for example: direction of movement arrows) A.3.6 Continuous operation symbols Symb ol elements repre s enti ng conti nuou s op eration o f mach i ne p ar ts , comp onents or fu nc tion s A.4 Base composite symbols When ne ce s s a r y, s ymb ol s repre s enti ng vita l mach i ne fluid s s hou ld be combi ne d with s ymb ol s repre s enti ng op erationa l s ys tem s to c re ate b a s e comp o s ite s ymb ol s For exa mple, the oi l (flu id) s ymb ol shou ld b e pl ace d with i n the engi ne s ymb ol to repre s ent engi ne oi l, with i n the tran s m i s s ion s ymb ol to repre s ent tran s m i s s ion oi l, with i n the hyd rau l ic s ys tem to repre s ent hyd rau l ic oi l a nd with i n the bra ke s ymb ol to repre s ent bra ke flu id A.5 Vital status composite symbols A.5.1 General C omp o s ite s ymb ol s repre s enti ng the s tatu s o f vita l flu id s or the shou ld b e forme d func tion i ng o f op erationa l s ys tem s b y combi n i ng mu ltip le s ymb ol elements i n lo gic

relative may vary as p o s itio n needed o f fluid fo r s tatus grap hical symb o ls clarity Fo r b as e co mp o s ite symb o ls fo r o p eratio nal examp le: co mp o s ite symb o ls fo r mo nito ring and fluid temp erature s ho uld co mb ine the thermo meter (the temp erature symb o l element) with the b as e co mp o s ite symb o l, with the thermo meter p laced to the right- hand s ide o f the b

e fo r mo nito ring the s tatus o f fluid filters s ho uld p lace the filter symb o l element b elo w the b as e co mp o s ite symb o l A.5.2.3 Fo r ap p licatio n in p ractice, the vital s tatus symb o l elements can als o be us ed in a s eries p res entatio n, with the b as e co mp o s ite symb o l lo cated to the le ft o r ab ove the p res entatio n o f vital s tatus symb o l elements Fo r examp le: the engine o il symb o l may b e fo llo wed by p res s ure, level o r temp erature symb o l elements This ap p ro ach, however, is generally les s des irab le than develo p ing and us ing individual co mp o s ite symb o ls 86 © ISO 2016 – All rights reserved ISO 3767-1:2016(E) A.5.3 Failure or malfunction symbols Composite symbols representing failure or mal function o f an operational system should place the mal function symbol element within the symbol for the operational system For example: the brake system failure symbol should place the exclamation mark (the mal function symbol element) inside the bake system symbol In some cases, the shape o f a symbol for the operational system does not permit inside placement o f the mal function symbol element In such cases, the mal function symbol element should be placed alongside the symbol for the operational system; to avoid fusion with the temperature symbol element, the mal function symbol element should be placed to the le ft-hand side o f the symbol for the operational system A.6 Movement or location symbols A.6.1 Controlled spatial movement symbols Composite symbols representing controlled spatial movement o f equipment or machine elements, whether visible or invisible to the operator, should show both the final position o f the equipment or machine element e ffected by actuation o f the controls and an arrow to indicate the direction o f movement experienced by that equipment or machine element A.6.1.1 A.6.1.2 For example: symbols on a control for raising a boom should show the boom it its raised position and a movement arrow pointing up Symbols on a control for lowering a boom should show the boom it its lowered position and a movement arrow pointing down The arrows should be located such and the location of the arrows that the two alternative motions o f the boom are clearly di fferentiated by both the location o f the boom A.6.2 Incremental adjustment symbols Composite symbols representing controls for incremental adjustment o f component position or operating parameters rather than significant changes in location or orientation should use dimension lines and dimension arrows to indicate adjustments A.7 Rotational movement symbols Composite symbols representing direction o f rotational movement should combine a symbol element for the equipment or machine element with arrows that differentiate clockwise or anti-clockwise rotation A.8 Symbols for component actuation Where symbols are associated with controls that actuate a functional component, it is recommended to use indicator lights, symbols for engage and disengage, or comparable means in association with the symbol representing the machine component being activated or deactivated A.9 International Standards on symbol development and arrow usage A.9.1 The development o f new symbols should form to the basic principles for the creation o f symbols for use on equipment (re ference IEC 80416-1) and to the principles for the use o f arrows (reference ISO 80416-2) A.9.2 As a general principle, there should be only one symbol for a given function As a practical matter, however, alternative symbols are permitted, in particular when there are multiple existing and wellestablished standard symbols or when a new symbol is needed and should be harmonized with other symbols for the same type o f © ISO 2016 – All rights reserved 87 ISO 3767-1:2016(E) Bibliography [1] [2] [3] [4] [5] [6] [7] ISO 3767-2, Tractors, machinery for agriculture and forestry, powered lawn and garden
