on the experience of the chemical and petrochemical industry and providesrequirements additional to those found in valve product standards.The user of the standard is free to decide to which valves it applies.Licensed Copy:FELIX HERZING,TUV RHEINLAND BERLIN BRANDENBURG 5954918,12 March 2004,Uncontrolled Copy,(c)BSIPage 4EN 12569:1999 BSI 06-20011ScopeThis European Standard applies to valves of DN15 and greater,made of metallic materials for chemical andpetrochemical plants.It contains additional requirements to those contained in the relevant Europeanproduct standards.Two levels of quality are included.All valves shall meet the requirements of level I.Valves shall meet therequirements of level II only when required by the order.NOTE:It is assumed that the essential safety requirements of the PED(satisfied by Europeanproduct standards)and safety requirements from other standards are satisfied.2Normative referencesThis European Standard incorporates,by dated or undated reference,provisions from other publications.These normative references are cited at the appropriate places in the text and the publications are listedhereafter.For dated references,subsequent amendments to or revisions of any of these publications apply tothis European Standard only when incorporated in it by amendment or revision.For undated references,thelatest edition of the publication

dot?indicate requirements to be specified by the purchaser.4.1GeneralThe design of the shell shall meet the requirements of prEN 12516-3:1999 or other accepted calculationmethods.The following additional force shall allow for the undefined external moments and forces that areproduced by the adjoining piping of the vessel:The additional force,FADD,shall be calculated from:FADD =ps x Awhere:ps is the allowable pressure,in newtons per square millimetre;A is the cross-sectional area(D x?/4),in square millimetres;D is the value of DN,in millimetres.Licensed Copy:FELIX HERZING,TUV RHEINLAND BERLIN BRANDENBURG 5954918,12 March 2004,Uncontrolled Copy,(c)BSIPage 6EN 12569:1999 BSI 06-2001It is assumed that the section modulus of the valve is equal to or greater than the adjacent pipe and that thematerials strengths are equal.Under these conditions it is assumed that correct function is preserved.For the visual inspection and the non-destructive tests,all pressure retaining parts shall have a surface finishwhich makes it possible to conduct the tests in accordance with table 1.?When fire test certification is required it shall be specified by the purchaser.Certification shall be inaccordance with prEN ISO 10497:1996 or other standard by agreement.The valve shall be asbestos free.?If the subcontractors are not certified in accordance with EN ISO 9000 series,(EN ISO 9001,EN ISO 9002,EN ISO 9003,as appropriate),the purchasers can require to be informed about the change ofsubcontractors for main parts of a valve(e.g.castings,forgings for valves).The purchaser shall be informedabout the use of subcontractors for complete valves.The manufacturer shall ensure in every case theinterchangeability of parts.4.2Quality assurance4.2.1Semi-product manufacturer(e.g.foundry,forge,welding shop)Semi-product manufacturers shall have suitable equipment and qualified personnel for proper manufacture oftheir materials and products.They shall have test equipment for tests according to applicable standards orother required technical specifications.These manufacturers shall ensure the proper manufacture andprocessing of the materials and products by means of a quality assurance system,in accordance withEN ISO 9000 series,(EN ISO 9001,EN ISO 9002,EN ISO 9003,as appropriate)audited at regular intervalsby an authorized representative(e.g.notified body).The documentation for materials or semi-products shall be made available to the purchaser on request.4.2.2Valve manufacturerThe valve manufacturer shall have suitable equipment and qualified personnel for the further processing ofthe materials or semi-products used.He shall operate a quality assurance system,in accordance withEN ISO 9000 series,(EN ISO 9001,EN ISO 9002,EN ISO 9003,as appropriate),audited at regular intervalsby an authorized representative(e.g.notified body).The purchaser has the right to witness the quality tests at the manufacturers and/or suppliers premises andto carry out quality audits.Documentation shall be made available to the purchaser on request.4.3Design4.3.1GeneralValves shall meet the design requirements of their specific product standards,if such exist.Where no applicable product standard exists safe and sound engineering practice,including the applicationof basic standards for industrial valves,shall apply.The following requirements concerning design shall apply to all valves.Licensed Copy:FELIX HERZING,TUV RHEINLAND BERLIN BRANDENBURG 5954918,12 March 2004,Uncontrolled Copy,(c)BSIPage 7EN 12569:1999 BSI 06-20014.3.2Anti-blow-out shaft/stemThe design of the shaft/stem shall be anti-blow-out type in accordance with EN 736-3.4.3.3GasketsGaskets of the shell shall be radially retained against the pressure,except in the case of body bonnet jointsup to and including PN 25(or Class 150)valves.Spiral wound gaskets sealing the body/cover connection shall be fully retained or provided with outer andinner guide rings.The sealing face of spiral wound gaskets and metallic ring-joint gaskets shall not be interrupted by bolts,ringsetc.4.3.4Fugitive emission control?When required,valves shall be fitted with a stem seal specifically designed to prevent fugitive emissions tothe atmosphere.If requested by the purchaser a type qualification test shall be carried out.The testprocedure and the acceptance criteria shall be as agreed.Where bellows and diaphragms are used as primary seals,they shall be provided with a secondary packingin case of rupture.4.3.5Anti-static protectionThe electrical resistance between body and obturator/stem of the valve shall not exceed106 ohms.4.3.6Screwed connectionsAll screwed connections,e.g.body/cover connections or screwed in parts of valves,shall be properly secured(e.g.by friction or locking)against accidental loosening.Screwed body/cover connections that rely on thethread to seal are not acceptable.The valve shall be designed so that the risk of media induced crevice corrosion will be avoided.4.3.7Wafer and lug type valvesWafer and lug type valves shall not require an increase in flange bolt load above that which is necessary toseal the valve/flange joints.4.3.8Position of the obturator/actuator in quarter turn valvesThe position of a lever or indicator shall be in the direction of the pipeline when the valve is open andperpendicular to the pipeline when the valve is close
