This part of GB/T 16903 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 part 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 signs designed in accordance with this part will, once understood, be complied with.
Note: Appropriate attitudes and motivation are required before compliance with any sign will result. A graphical sign is not intended as an easy alternative to surveillance, physical barriers, education or other means of achieving a safe situation.
