1.6.62 Means of Illumination
Examples of means of illumination of signs are as follows:
(a) A light within or behind the sign face, illuminating the main message or symbol, or the sign background or both, through a translucent material.
(b) An attached or independently mounted light source in front of the sign. designed to direct adequate illumination over its entire face.
NOTE Stray light from such a source should not be allowed to become a glare source for traffic approaching from the opposite direction.
(c) Electronic presentation of legend and other sign elements (signs prohibiting turns and speed limit signs are permitted to have a black background under this option).
1.6.6.3 Means of reflectorization
Reflectorization is achieved by using retroreflective materials conforming with AS/NZS 1906.1 and rellectorizing all elements of a sign except black.
Except in a few limited cases in the AS 1742 series where a performance Class from AS/NZS 1906.1 is specified for a particular sign or class of signs, the user selects an appropriate performance Class according to the sign location, positioning and any environmental or other relevant factors.
Advice on the selection and use of retroreflective sheeting is given in AS/NZS 1906.1.
1.7 Sign size
As indicaied áfl( ,IU’L 1.S.l(d)mostofthesigns are provided in a range of sizes designated AA(sniallest) up to A, B, C, D or E. Guidance in the selection of the size of sign for use In a particular location is given in the part of the Standard covering the use of the sign.
1.8 Non-standard signs
Authorities responsible for the erection of signs are not encouraged to develop signs for their own particular use. However, there will he instances where there is no suitable standard sign. In such cases, the sign developed should conform to the design requirements specified in this document for the particular sign classification, and with the requirements of Clause 1.6.5 If use of symbols is proposed. lilt is considered that the sign could be required by other authorities, contact should be made with Standards Australia, which constantly reviews road signs to ensure that the needs of road and traffic authorities and local government are met, and to minimize the proliferation of signs with differing designs of legend or symbol. Where an authority develops its own sign, it is recommended that it identifies the jurisdiction by its relevant prefix before the sign number. For example, in Victoria, a typical sign number could be “W3.V123.
