适用范围：This British Standard specifies tests and performance requirements, and produces photometric ratings, for microprismatic retroreflective sheeting material for use in vertical road traffic signs. It is not applicable to materials based on glass bead technology (microspheric) or materials intended for use in microprismatic transilluminated signs. NOTE 1 The retroreflective performance of microprismatic materials can be affected if the sign is tilted; the photometric rating method presumes vertically. NOTE 2 This standard complements BS EN 12899-1, which specifies requirements for other components of vertical road traffic signs. NOTE 3 Although the requirements of this British Standard are for the manufacturer of sign sheeting and the sign maker, Annex G and Annex I give guidance to the specifying road authority on the selection of, respectively, entrance angularity subclasses and sheeting.
