19、nical Committee CEN/TC 210 “GRP tanks and vessels”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2006, and conflicting national standards shall be w
20、ithdrawn at the latest by May 2006. This European Standard falls under the Pressure Equipment Directive (PED) and supports essential require-ments of this EC Directive. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. According to
21、the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Den-mark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Lux

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.
