30、and definitions given in EN ISO 472 and the following apply. 3.1 pultrusion continuous production process for the manufacture of composite profiles, by pulling layers of fibrous materials, impregnated with a synthetic resin, through a temperature controlled die, and by curing and/or cooling the resi

32、BSI EN 13706-2:2002 (E) 5 3.3 structural area of application of pultruded profiles where the load bearing characteristic is the major criterion of design and where the product is part of a load bearing system. For the purposes of this standard the minimum mechanical properties for a profile to be cl
33、assified as structural is one which meets the minimum properties of grade E17 as defined in Table 1 of 4.4 in EN 13706-3:2002 3.4 reinforcement layer discrete layer of reinforcement comprising of one type of fibre format, such as unidirectional rovings, mat or fabric 3.5 transverse reinforcement rei
34、nforcement included to provide the required level of properties in the direction transverse to the pultrusion axis (e.g. mat, fabric) 4 General requirements 4.1 Appearance The pultrusion shall meet the requirements given in annex A, “Visual Defects: Descriptions and Acceptance Levels”. 4.2 Dimension
35、al tolerance The pultrusion shall meet the requirements given in annex B, “Dimensional Tolerances for Pultruded Profiles”. 4.3 Workmanship The pultrusion shall meet the requirements given in annex C, “Workmanship”. 5 Sampling 5.1 General The properties of pultruded profiles shall be measured by the
36、manufacturer in accordance with a recognised quality control scheme and documented in the form of a certificate of conformity. 5.2 Certificate of Conformity Where required by the customer a certificate of conformity shall be issued identifying both the obligatory properties as defined in EN 13706-3,
37、 plus other optional tests as may be agreed between customer and supplier. The certificate shall comply with the requirements of EN 10204. 5.3 Resolution of quality issues In the case when issues of quality arise between customer and supplier, re-testing of the material is necessary. The sampling an
38、d tests shall be undertaken as agreed between customer and supplier. 6 Preparation of plates and test specimens Test specimens shall be cut from the profile where the dimensions of the profile permit (see 6.2.2). In other cases, a test plate can be used to simulate the pultrusion for the determinati
39、on of the laminate properties for design or qualification purposes.

40、flat strip die. For test specimens cut only in the direction of production, the flat strip shall be a minimum of 50 mm wide. If properties perpendicular to the direction of production are required, the flat strip shall be a minimum of 250 mm wide. The thickness of the flat strip shall be the same as
41、 the profile being simulated. The raw materials used, the laminate construction and the production parameters (die temperature, pull speed, etc.) of the test plate shall match as closely as possible the intended production conditions of the profile being simulated. 6.2 Preparation of specimens 6.2.1
42、 Dimensions Test specimens shall be cut to the dimensions and tolerances given in the individual test methods. 6.2.2 Cutting of test specimens Test specimens shall not be taken closer than 10 mm to the edges or change in section of a profile. The cutting of test specimens shall be undertaken in such
43、 a way that any resultant edge defects do not adversely affect the test results. One of the following three procedures may be used. 6.2.2.1 Milling Test specimens may be cut from the test plaque using a duplicating or CNC milling machine. 6.2.2.2 Sawing Test specimens may be cut from the test plaque
44、 using a circular saw fitted with a hardened metal or diamond edged saw blade. Alternative techniques such as laser or water jet cutting are also acceptable if meeting the above quality requirements. 6.2.2.3 Pre-cutting Test specimens may be cut by any convenient means to a minimum of 5 mm over the
45、specified width of the test specimen. 5 or 10 test specimens may then be packed together and milled to size as a block. 6.3 Profile full section test specimens A profile full section test shall be used to determine the effective full section flexural modulus as required in clause 4 of EN 13706-3:200
46、2 using the test method described in annex D. Samples for the profile full section test shall be selected in accordance with the criteria given in clause 5 of this Part 2. The samples selected shall be cut square at the ends and of sufficient length for the intended test (see annex D of Part 2), and
47、 free from obvious production or other defects as listed in annexes B and C.
