簡介：發(fā)泡聚苯乙烯歐盟強制CE認證

簡介：發(fā)泡聚苯乙烯歐盟強制CE認證發(fā)泡聚苯乙烯(EPS)CE認證–需要符合的產(chǎn)品指令和協(xié)調(diào)標準A．產(chǎn)品指令：建筑產(chǎn)品法規(guī)CPR(ConstructionProductRegulation)305/2011/EUB．歐洲協(xié)調(diào)標準：EN14309建筑設(shè)備和工業(yè)裝置用隔熱產(chǎn)品-工廠制發(fā)泡聚苯乙烯(EPS)產(chǎn)品Thermalinsulationproductsforbuildingequipmentandindustrialinstallations.Factorymadeproductsofexpandedpolystyrene(EPS).Specification;根據(jù)EN14309標準，發(fā)泡聚苯乙烯（EPS）CE認證需要做以下測試項目：燃燒性能測試：評估產(chǎn)品在火災(zāi)發(fā)生時的燃燒特性，燃燒性能測試是為了確保保溫材料在建筑使用中符合相應(yīng)的防火安全要求，減少火災(zāi)風險，保護人員和財產(chǎn)安全。（必做項目）導熱系數(shù)測試：該測試用于評估產(chǎn)品的保溫隔熱性能，即熱量通過材料傳遞的難易程度。較低的導熱系數(shù)意味著更好的保溫效果，能夠有效減少熱量的傳遞，降低能源消耗，提高建筑物的能源效率.壓縮強度測試：檢測產(chǎn)品在受到壓縮力作用時的承載能力和變形情況。足夠的壓縮強度可確保保溫材料在使用過程中能夠承受外部壓力，如建筑物自重、風荷載等，而不會發(fā)生過度變形或損壞。彎曲強度測試：評估產(chǎn)品在承受彎曲力時的強度和韌性。彎曲強度對于一些需要在彎曲狀態(tài)下使用的保溫材料或保溫結(jié)構(gòu)部件尤為重要，它反映了材料抵抗彎曲變形和破壞的能力。剪切強度測試：確定產(chǎn)品在受到剪切力作用時的抗剪能力。剪切強度的測試有助于評估保溫材料在不同受力情況下的穩(wěn)定性和可靠性，特別是在保溫系統(tǒng)中存在不同材料層之間的連接或相互作用時。水蒸氣透過率測試：測量產(chǎn)品對水蒸氣的透過性能。低水蒸氣透過率可防止水分進入保溫層，避免因水分積聚導致的保溫性能下降、材料腐蝕等問題，從而保證保溫系統(tǒng)的長期有效性.EN14309認證是產(chǎn)品進入歐洲市場的關(guān)鍵通行證。在歐盟建筑市場中，建筑保溫材料受到嚴格監(jiān)管。如果產(chǎn)品未獲得EN14309認證，將無法在歐盟國家合法銷售和使用。這就如同產(chǎn)品獲得了在歐盟建筑保溫領(lǐng)域的“入場券”，為產(chǎn)品開拓廣闊的歐洲市場奠定了基礎(chǔ)。Introduction:ExpandedpolystyreneEUmandatoryCEcertificationExpandedpolystyrene(EPS)CEcertification–ProductdirectivesandcoordinatedstandardsthatneedtobemetProductDirectives:CPR(ConstructionProductRegulation)305/2011/EUEuropeanharmonizedstandards:EN14309Thermalinsulationproductsforbuildingequipmentandindustrialinstallations.Factorymadeproductsofexpandedpolystyrene(EPS).Specification;AccordingtotheEN14309standard,thefollowingtestitemsarerequiredfortheCEcertificationofexpandedpolystyrene(EPS):Combustionperformancetest:Evaluatethecombustioncharacteristicsoftheproductwhenafireoccurs.Thecombustionperformancetestistoensurethattheinsulationmaterialmeetsthecorrespondingfiresafetyrequirementsintheuseofbuildings,reducefirerisks,andprotectthesafetyofpeopleandproperty.(Requireditems)Thermalconductivitytest:Thistestisusedtoevaluatethethermalinsulationperformanceoftheproduct,thatis,theeasewithwhichheatistransferredthroughthematerial.Lowerthermalconductivitymeansbetterinsulationeffect,whichcaneffectivelyreduceheattransfer,reduceenergyconsumption,andimprovetheenergyefficiencyofbuildings.Compressionstrengthtest:Detectthebearingcapacityanddeformationoftheproductwhensubjectedtocompression.Sufficientcompressionstrengthensuresthattheinsulationmaterialcanwithstandexternalpressureduringuse,suchastheweightofthebuilding,windload,etc.,withoutexcessivedeformationordamage.Bendingstrengthtest:Evaluatethestrengthandtoughnessoftheproductwhensubjectedtobendingforce.Bendingstrengthisparticularlyimportantforsomeinsulationmaterialsorinsulationstructuralcomponentsthatneedtobeusedinabentstate.Itreflectstheabilityofthematerialtoresistbendingdeformationanddamage.Shearstrengthtest:Determinetheshearresistanceoftheproductwhensubjectedtoshearforce.Shearstrengthtestinghelpsevaluatethestabilityandreliabilityofinsulationmaterialsunderdifferentstressconditions,especiallywhenthereareconnectionsorinteractionsbetweendifferentmateriallayersintheinsulationsystem.Watervaportransmissionratetest:Measuresthepermeabilityoftheproducttowatervapor.Lowwatervaportransmissionratepreventsmoisturefromenteringtheinsulationlayer,avoidingproblemssuchasreducedinsulationperformanceandmaterialcorrosioncausedbymoistureaccumulation,therebyensuringthelong-termeffectivenessoftheinsulationsystem.EN14309certificationisakeypassportforproductstoentertheEuropeanmarket.IntheEUconstructionmarket,buildinginsulationmaterialsarestrictlyregulated.IfaproductdoesnotobtainEN14309certification,itcannotbelegall
