Graphical symbols -- Test methods for judged comprehensibility and for comprehension
This International Standard specifies:
- the procedure to be used in gathering the information needed to request standardization of graphical symbols;
- the method to be used in testing which variant of a graphical symbol is judged the most comprehensible; and
- the method to be used in testing the extent to which a variant of a graphical symbol communicates its intended message.
The purpose of this International Standard is to ensure that graphical symbols, and signs using graphical symbols, are readily understood. It in no way ensures that prohibitions or warnings using graphical symbols or symbol signs designed in accordance with this International Standard will, once understood, be complied with.
