DESIGN PROCEDURES TO ENSURE THE LEGIBILITY OF SYMBOLIC SIGNS HAVE NOT BEEN DEVELOPED TO THE EXTENT THAT SIMILAR PROCEDURES HAVE FOR VERBAL SIGNS. THE THREE PARAMETERS OF LUMINANCE, CONTRAST AND SIZE ARE CONSIDERED IN THE LIGHT OF RECENT RESEARCH INTO THE VISIBILITY OF SYMBOLIC SIGNS AND A PROCEDURE IS DEVELOPED WHICH WILL ENSURE THAT SIGNIFICANT DETAIL, NECESSARY FOR THE COMPREHENSION OF THE SYMBOLIC IMAGE INCORPORATED IN THE SIGN, IS SUFFICIENTLY LEGIBLE FOR DEFINED POPULATIONS UNDER THE INTENDED CONDITIONS OF USE. THE PROCEDURE HAS BEEN INCORPORATED INTO STANDARDS FOR THE DESIGN AND USE OF GRAPHIC SYMBOLS AND PUBLIC INFORMATION SYMBOL SIGNS BY THE STANDARDS ASSOCIATION OF AUSTRALIA AND SIMILAR METHODS ARE UNDER CONSIDERATION BY THE INTERNATIONAL STANDARDS ORGANISATION (A). THE NUMBER OF THE COVERING ABSTRACT OF THE CONFERENCE IS IRRD NO 255423.
