IEC 80416-1 pdf downoad – Basic principles for graphical symbols for use on equipment
1 scope
International Standard 80416 series provides principles and guidelines for the creation ofsymbol originals and the application of graphical symbols for use on equipment prepared withiniso and lEc.
This Part 1 of the standard specifies the key principles for the creation of symbol originals foruse on equipment. In accordance with the intended meaning of the symbol originals, it containsrules for design such as shape and size, and also for preparation of the accompanying texts.
This standard applies to graphical symbols used:
– to identify the equipment or a part of the equipment (for example, a control or display);- to indicate functional states or functions (for example, on, off,alarm);
– to designate connections (for example, terminals, filling points);
to provide information on packaging (for example,identification of content,instructionsfor handling);
– to provide instructions for the operation of the equipment (for example,limitations of
This standard does not apply to symbol originals for:- safety signs;
use on drawings and diagrams;
use in technical documentation of products and in technical product documentation;- use for public information.

3 Definitions
For the purpose of this International Standard, the following definitions apply.
graphical symbol
visually perceptible figure with a particular meaning used to transmit information independentlyof language
graphical symbol element
part of a symbol original with a particular meaning
NOTE 1 Letters,numerals,punctuation marks and mathematical symbols may be used as graphical symbolelements (see lso31 and lEC60027).
NOTE 2 A graphical symbol element with a specific meaning may be used to provide a common concept in theconstruction of a symbol family.
symbol original
drawing of a graphical symbol,prepared in accordance with this standard,used for referenceor reproduction purposes
corner marking
part of a symbol original, four of which define the frame of the symbol original; see 7.3 andfigure 8
unique name by which a graphical symbol is identified and spoken of
NOTEThe title should be as short as possible; it is only intended to provide a unique name for the graphicalsymbol and not to describe its application.
normative text attached to the graphical representation of the symbol original which defines thepurpose, the application and the use of the symbol original
The meaning assigned to each symbol original is the result of associating a title, a graphicalrepresentation and a description of the application. The assigned meaning should be un-ambiguous and independent of terms related to a special technique or discipline.
4.2 Orientation of graphical symbols Graphical symbols should normally be used in the orientation specified by the symbol originals. Care should be taken to avoid ambiguity during creation of symbol originals and subsequent use of graphical symbols whose meaning is dependent on their orientation. Such ambiguity could occur, for instance, when graphical symbols are placed on rotary knobs. Symbol originals should whenever possible be created so as to preserve their meaning in any orientation as the example a) in figure 1. However, when the meaning of a graphical symbol does depend on its orientation, as in the case of the examples b) in figure 1, this shall be explicitly stated in the description of the symbol original.
5 Combination of graphical symbols To represent certain concepts, graphical symbols or graphical symbol elements may be com- bined to form a new symbol original. The meaning assigned to the new symbol original shall be consistent with the meanings of the individual graphical symbols or graphical symbol element used as shown in figure 2.
