1.1 This Part 1 of EN 13706 establishes a data block system for the designation of pultruded profiles made from fibre reinforced plastics composites. 1.2 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). 1.3 This European Standard is applicable to pultruded profiles made from fibre reinforced plastics composites only. It applies to materials ready for use in the form of straight lengths of section, or in coils, for structural applications (see clause 3.3 EN 13706-2:2002). This European Standard does not apply to the following types of pultruded profile : - profiles designed primarily for their electrical properties ; - profiles which are classified as non-structural, that is having properties below the minimum required to conform to the grade E17 (see Table 1 of clause 4.4, EN 13706-3:2002). 1.4 This Part 1 of EN 13706 does not provide engineering data, performance data or data on service conditions which can be required to specify a profile for a particular application. If such additional properties are required, when ever possible, they shall be determined in accordance with the test methods specified in Part 2 of EN 13706.
