1 Scope
This standard specifies the classification, technical requirements, test method, inspection rules, marking, packaging, transportation and storage of retroreflective sheeting for traffic control (hereafter referred to as “retroreflective sheeting”).
This standard is applicable to retroreflective sheeting used in traffic management and operation facilities such as road traffic signs, delineator, traffic cones, traffic columns, crash barrels (cushions), road fences, etc., and retroreflective sheeting used in other transportation such as water transport, aviation and railway can be implemented with reference.
