Conspicuity is enhanced by high contrast between the vest ambient background and the work environment. This standard provides performance requirement of conspicuous materials to be used in high-visibility public safety vests and specifies minimum areas and placement of the materials. This standard specifies minimum amounts of retroreflective materials, colors and placement of materials, for vests used to enhance the visibility of public safety workers. Performance requirements are included for color, retroreflection and minimum areas, as well as the suggested configuration of highly visible materials used in the construction of high-visibility public safety vests. Test methods are provided in the standard to ensure that a minimum level of visibility is maintained when items are subjected to ongoing care procedures.
