20、EN 13923:2005) has been prepared by Technical 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 c

21、onflicting national standards shall be withdrawn at the latest by May 2006.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

22、of this European Standard. According to 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

24、ard specifies two design methods for filament wound GRP pressure vessels. In this European Standard only the winding is considered 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 ba

25、sed on netting theory. The design is verified by prototype testing. Method B, describes the calculation of the reinforcement 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,

26、 such as resins, thermoplastics and reinforcement fibres. It is implicit that vessels conforming to this European Standard should be made only by manufacturers and operators who are competent and suitably equipped to fulfil all requirements, using materials manufactured by competent and experienced

27、material manufacturers. This European Standard specifies stress and strain limits and the requirements for the acceptance testing. Licensed Copy: Wang Bin, na, Tue May 09 02:38:12 BST 2006, Uncontrolled Copy, (c) BSIEN 13923:2005 (E) 5 1 Scope This European Standard specifies the requirements for th

28、e 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-directional filament winding, made in a factory and for use above ground and for storage and pr

29、ocessing 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 vessels, vessels under nega-tive pressure, vessels which are subjected to the risk of expl

30、osion 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.
