This Part2 of EN12899 specifies requirements for new transilluminated traffic bollards (TTBs) including their fixing, which may incorporate traffic signs (type1 TTB) or may support traffic signs (type2 TTB) to be used in traffic circulation areas. It covers performance requirements and test methods. Colorimetric and retroreflective properties as well as luminance of transilluminated illuminated portions are specified taking into account CIE recommendations. Structural requirements for TTBs include performance under static and dynamic loading. Provision is made for safety in use, including vehicle impact. Devices of similar function, but without transillumination or less than 600mm in height, are not covered. NOTE Foundations are not specified in this standard but should be adequate to support the loads to be carried. Unless otherwise stated, clauses in this standard apply to both type1 and type2 TTBs.
