This part 3 Of ENxxxx defines the specification of pultruded profiles. The specification defines those properties which shall be specified and the level to be obtained for each grade of profile. The specification defines grades where the short-form code, Exx, is related to the Young's modulus of the material measured by testing a length of the full section profile. Two grades; E23 and E17 are defined. Note: Other grades may be introduced at future revisions of the standard. The properties which shall be achieved for each class of profile are given in Table 1. Other properties that may be reported are listed in Table 2.
