Rules for the presentation of graphical symbols for
use on signs - Design principles and requirements for
public information graphical symbols
1 Scope
This standard establishes the rules for the presentation of graphical symbols
for use on signs; specifies the requirements for design procedures, design
template, design principles, specific graphic design of the public information
graphical symbols (hereinafter referred to as graphical symbols); specifies the
rules of forming graphic signs through the graphical symbols.
This standard applies to the design of public information graphical symbols.
This standard does not apply to the design of graphical symbols, which are
used in safety signs and road traffic signs.
2 Normative references
The following documents are essential to the application of this document. For
the dated documents, only the versions with the dates indicated are applicable
to this document; for the undated documents, only the latest version (including
all the amendments) is applicable to this standard.
GB/T 10001 (all parts) Public information graphical symbols
GB/T 15565 Graphical symbols - Terms
GB/T 16900 Rules for the presentation of graphical symbols - General
principles
GB/T 16900.2 Rules for the presentation of graphical symbols - Part 2:
Methods for testing comprehensibility

graphical signs - Part 3: Method for testing perceptibility
3 Terms and definitions
The terms and definitions, which are defined in GB/T 15565, are applicable to
this document.
4 Design procedures
The design of graphical symbols shall adhere to the provisions of GB/T 16900,
as well as the following design procedures:
a) Confirm that the graphical symbols to be designed are NEITHER safety
signs NOR non-sign graphical symbols;
b) Clarify the object to be expressed of the graphical symbol to be designed
AND its meaning;
c) Analyze the expected use environment of the graphical symbols AND
characteristics of user groups;
d) Confirm that the GB/T 10001 (all parts) and other relevant national
standards have no graphical symbols, which are same as the meanings
of the graphic signs to be designed;
e) Give meaning to the graphical symbols to be designed; give descriptions
of functions and application scenario;
f) Search for the possible symbol elements, which are used to present
relevant meaning, the symbol elements in the graphical symbols, the
graphical symbols which can be used as elements, from the current
standards; combine these symbol elements, to form new graphical symbol;
g) If the graphical symbol cannot be formed, by directly using or combining
existing symbols, THEN, use the design template, which is specified in
Chapter 6, to design the graphical symbol, in accordance with the graphic
design requirements specified in Chapter 7;
h) Follow the requirements of GB/T 16900.2 and GB/T 16903.31), to test the
graphical symbols, to evaluate the comprehensibility and perceptibility of
graphical symbols in the use environment;
i) Determine the graphical symbols; fine-tune the graphical symbols, to have
beautiful vision and consistent composition.
1 This standard is proposed to be revised AND re-numbered to GB/T 16900.3 (see Foreword).
the graphics, which are related to popular pattern, as the symbol elements;
e) Make the styles of graphical symbols in the same field consistent;
f) Make the overall length and width ratio of the graphics less than 3:1;
g) Consider the impact on the comprehensibility of symbols, after adding
negation factors (negation slashes);
h) Consist of figurative forms.
7.2 Use of characters
7.2.1 Letters, numbers, punctuation marks, mathematical symbols and other
characters should only be used as symbol elements.
7.2.2 If some letters or punctuation marks have been widely recognized, THEN,
they can be used alone as graphical symbols, such as the letter "P" for parking
lots, the punctuation mark "?" for information query.
7.3 Combination of graphical symbols and/or symbol elements
7.3.1 If a new symbol graphic is the combination of two or more graphical
symbols or symbol elements (see Figure 6), THEN, the meaning of the new
graphical symbol shall be composed of a combination of the original graphical
symbols or the meaning of symbol elements.
7.6 Size of line width, gap, symbol elements in design template
7.6.1 When designing graphical symbols, according to needs, the size of line
width can be selected as 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm; the gap size can
be selected as 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm; in special cases (such as the
gap between the humanoid arm and body), it may use the gap size of 1.5 mm.
7.6.2 In order to ensure that the graphical symbol, which is designed in the
template, can still maintain visual clarity, when it is reduced to 10 mm x 10 mm
(see Figure 11b)], the minimum line width in the graphical symbol shall not be
less than 2.5 mm; the minimum gap between symbol details should not be less
than 2.0 mm [see Figure 11a)].
7.6.3 For graphical symbols, which are composed of two or more symbol
elements, the gap between symbol details within the symbol element shall be
smaller than the gap between the symbol elements.
7.6.4 The size of the smallest symbol element in the graphical symbol shall not
be less than 3.0 mm x 3.0 mm (see Figure 12).
