This part of ENxxxx establishes a data block system for the designation of pultruded profiles made from fibre reinforced plastic composites. The types of pultruded profiles are differentiated from each other by a classification system based on information about type of polymer matrix used, the reinforcement material, the type of reinforcement and the additional in-service performance features (e.g.fire retardancy, UV stability). This European Standard is applicable to pultuded profiles made from fibre reinforced plastic composites only.
