EN 13923:2005 (E) 4 Introduction This European Standard specifies two design methods for filament wound GRP pressure vessels. In this European Standard only the winding is consi

23、dered in the calculation of the strength and the stiffness of the shell. Method A, describes the calculation of the reinforcement of the cylindrical shell and the end domes based on netting theory. The design is verified by prototype testing. Method B, describes the calculation of the reinforcement

24、of the cylindrical shell and the end domes based on laminate theory. The design and manufacture of filament wound GRP pressure vessels involve a number of different materials, such as resins, thermoplastics and reinforcement fibres. It is implicit that vessels conforming to this European Standard sh

25、ould be made only by manufacturers and operators who are competent and suitably equipped to fulfil all requirements, using materials manufactured by competent and experienced material manufacturers. This European Standard specifies stress and strain limits and the requirements for the acceptance tes

26、ting. EN 13923:2005 (E) 5 1 Scope This European Standard specifies the requirements for the design including raw materials, calculation, manu-facturing including composite materials, and testing of seamless Glass Reinforced Plastic (GRP) pressure vessels with protective layer, using only multi-direc

27、tional filament winding, made in a factory and for use above ground and for storage and processing of fluids. This European Standard covers vessels subject to pressures below 20 MPa and temperatures between 30 C and 120 C. Excluded from this European Standard are transportation vessels, double wall

28、vessels, vessels under nega-tive pressure, vessels which are subjected to the risk of explosion or failure of which may cause an emission of radioactivity. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
