18、 13473-312001 1 Scope This Part 3 of EN 13473 is a specification of multi-axial multi-ply fabrics made from reinforcement yarns, tows, rovings, fibre fleeces, films, foams or other materials which are intended to provide reinforcement in composite materials and which is bound to a multi-ply construc
19、tion. This specification defines those parameters which are required for a particular application or processing method. The parameter specifications do not define absolute or nominal values for any parameter. The values for specified parameters are defined by the application. This specification defi
20、nes the test methods which shall be used to determine the values and tolerances for each specified parameter to be controlled by the textile manufacturer. The parameters which shall be defined in the technical specification of multi-axial multi-ply fabrics are defined in clause 4 of this Part. 2 Nor

25、minal values of the parameters shall be defined in accordance to the following division into three groups: The parameters and tolerances in group 1 shall be designated and controlled by the textile manufacturer. The parameters in group 2 shall be designated but not controlled by the textile manufact
26、urer. The parameters of group 3 neither have to be designated nor controlled by the textile manufacturer, but can be optionally agreed. 4.2 Parameters to be designated and controlled (group 1) Table 1 describes the test methods of the parameters which need to be designated and controlled. In additio
27、n the tolerances for the single parameter are defined. Parameters for special applications may differ from the tolerance values and have to be agreed.

29、eters (e.9. filament diameter, sizing or finish, .) and other physical properties (see EN 13473-2:2001, 4.1, Table 1) are depending on the application. The tolerances and the values of these optional parameters and properties can be defined and agreed between the textile manufacturer and the custome
30、r. In case of any agreement, the additional parameters and properties have to be designated, too. 5 Example For the typical application in a windmill rotor blade the following example of a multi-axial multi-ply fabric is explained : - E-glass reinforcement yarn, filament diameter 17 pm, UP/EP compat
