Specifies performance requirements for two types of discrete retroreflectors which have higher photometric performance than sheet materials specified in AS/NZS 1906.1. The first type of device is intended to provide roadside delineation at night. The dimensions specified make them suitable for attachment to 100 mm wide guideposts. The second type of device is intended for use as sign legend buttons.

This standard specifies in general terms the performance requirements of retroreflective devices (known as 'retroreflectors') intended for use as roadside delineators and as road sign button reflectors. It also specifies in specific terms the performance requirements where retroreflectors are of the corner-cube variety. It applies to retroreflectors which are located above or to one side of the carriageway, displaying a vertical or near vertical face to traffic, and excludes devices which are placed directly on the pavement surface.
