建筑彩鋼板銷往美國(guó)市場(chǎng)要拿到ASTME 119耐火報(bào)告

建筑彩鋼板銷往美國(guó)市場(chǎng)要拿到ASTME119耐火報(bào)告彩鋼板在建筑領(lǐng)域的使用：工業(yè)建筑：在工廠廠房、倉(cāng)庫(kù)等工業(yè)建筑中，彩鋼板被廣泛用于屋面和墻面。其輕質(zhì)高強(qiáng)的特點(diǎn)使得廠房的結(jié)構(gòu)負(fù)擔(dān)較小，而且安裝速度快，可以大大縮短建筑工期。例如，在一些大型物流倉(cāng)庫(kù)中，彩鋼板屋面和墻面能夠提供良好的防雨、防風(fēng)和防曬功能。民用建筑：在住宅、公寓等民用建筑中，彩鋼板也有應(yīng)用。如在一些臨時(shí)住宅或活動(dòng)房屋中，彩鋼板作為主要的建筑材料，可以快速搭建起居住空間。同時(shí)，在建筑的外立面裝飾方面，彩鋼板也能起到美化建筑外觀的作用。美國(guó)耐燃測(cè)試標(biāo)準(zhǔn)：ASTME119StandardTestMethodsforFireTestsofBuildingConstructionandMaterialsASTME119建筑及材料防火測(cè)試方法標(biāo)準(zhǔn)建筑彩鋼板ASTME119耐火2小時(shí)測(cè)試是一項(xiàng)重要的檢測(cè)，用于評(píng)估彩鋼板在火災(zāi)情況下的耐火性能是否能夠達(dá)到特定要求。那么你知道測(cè)試前的一些須知事項(xiàng)嗎？ASTME119測(cè)試前須知事項(xiàng)：測(cè)試設(shè)備與環(huán)境：火爐：測(cè)試使用的火爐能夠提供符合標(biāo)準(zhǔn)要求的加熱條件，產(chǎn)生特定的溫度曲線。溫度曲線是測(cè)試的關(guān)鍵因素之一，規(guī)定了在不同時(shí)間點(diǎn)應(yīng)達(dá)到的溫度。熱電偶：用于測(cè)量火爐內(nèi)以及彩鋼板不同部位的溫度。熱電偶的布置需要嚴(yán)格按照標(biāo)準(zhǔn)要求進(jìn)行，以確保溫度測(cè)量的準(zhǔn)確性。環(huán)境條件：測(cè)試環(huán)境需要保持穩(wěn)定，避免外界因素對(duì)測(cè)試結(jié)果產(chǎn)生干擾。測(cè)試過(guò)程：樣品準(zhǔn)備：選取具有代表性的彩鋼板樣品，樣品的尺寸和規(guī)格應(yīng)符合ASTME119標(biāo)準(zhǔn)的要求。安裝樣品：將彩鋼板樣品安裝在測(cè)試設(shè)備中，確保樣品安裝牢固，并且與測(cè)試設(shè)備的接觸良好，以模擬實(shí)際建筑中的使用情況。加熱過(guò)程：按照標(biāo)準(zhǔn)規(guī)定的時(shí)間-溫度曲線對(duì)火爐進(jìn)行加熱，使火爐內(nèi)的溫度逐漸升高。在加熱過(guò)程中，需要實(shí)時(shí)監(jiān)測(cè)彩鋼板的溫度變化以及其他相關(guān)參數(shù)。觀察與記錄：在測(cè)試過(guò)程中，密切觀察彩鋼板的狀態(tài)，包括是否出現(xiàn)變形、剝落、裂縫等現(xiàn)象，并記錄下來(lái)。同時(shí)，記錄彩鋼板背火面的溫度變化、火焰穿透情況等信息。評(píng)估指標(biāo)：耐火時(shí)間：最主要的評(píng)估指標(biāo)是彩鋼板能夠在標(biāo)準(zhǔn)的火災(zāi)條件下保持耐火性能的時(shí)間。對(duì)于耐火2小時(shí)測(cè)試，彩鋼板需要在2小時(shí)內(nèi)保持其結(jié)構(gòu)完整性和隔熱性（如果適用），即不出現(xiàn)嚴(yán)重的變形、坍塌、火焰穿透等情況。耐火完整性：在標(biāo)準(zhǔn)耐火試驗(yàn)條件下,建筑分隔構(gòu)件當(dāng)某一面受火時(shí),能在一定時(shí)間內(nèi)防止火焰和熱氣穿透或在背火面出現(xiàn)火焰的能力。耐火隔熱性：在標(biāo)準(zhǔn)耐火試驗(yàn)條件下,建筑分隔構(gòu)件當(dāng)某一面受火時(shí),能在一定時(shí)間內(nèi)其背火面溫度不超過(guò)規(guī)定值的能力。ASTME119fireresistancereportisrequiredforbuildingcolorsteelplatessoldtotheUSmarketUseofcolorsteelplatesintheconstructionfield:Industrialbuildings:Inindustrialbuildingssuchasfactorybuildingsandwarehouses,colorsteelplatesarewidelyusedforroofsandwalls.Itslightweightandhighstrengthmakethestructuralburdenofthefactorybuildingssmaller,andtheinstallationspeedisfast,whichcangreatlyshortentheconstructionperiod.Forexample,insomelargelogisticswarehouses,colorsteelplateroofsandwallscanprovidegoodrain,windandsunprotection.Civilbuildings:Colorsteelplatesarealsousedincivilbuildingssuchashousesandapartments.Forexample,insometemporaryhousesormobilehouses,colorsteelplatesareusedasthemainbuildingmaterialstoquicklybuildlivingspaces.Atthesametime,inthedecorationofthefacadeofthebuilding,colorsteelplatescanalsoplayaroleinbeautifyingtheappearanceofthebuilding.Americanflameretardantteststandard:ASTME119StandardTestMethodsforFireTestsofBuildingConstructionandMaterialsTheASTME119fireresistance2-hourtestforbuildingcolorsteelplatesisanimportanttestusedtoevaluatewhetherthefireresistanceperformanceofcolorsteelplatesinfireconditionscanmeetspecificrequirements.Sodoyouknowsomethingstoknowbeforethetest?ThingstoknowbeforeASTME119test:Testequipmentandenvironment:Furnace:Thefurnaceusedinthetestcanprovideheatingconditionsthatmeetthestandardrequirementsandproduceaspecifictemperaturecurve.Thetemperaturecurveisoneofthekeyfactorsinthetestandspecifiesthetemperaturetobereachedatdifferenttimepoints.Thermocouple:Usedtomeasurethetemperatureinthefurnaceanddifferentpartsofthecolorsteelplate.Thelayoutofthethermocoupleneedstobestrictlyinaccordancewiththestandardrequirementstoensuretheaccuracyoftemperaturemeasurement.Environmentalconditions:Thetestenvironmentneedstobestabletoavoidexternalfactorsfrominterferingwiththetestresults.Testprocess:Samplepreparation:Selectrepresentativecolorsteelplatesamples,andthesizeandspecificationsofthesamplesshouldmeettherequirementsofASTME119standard.Installthesample:Installthecolorsteelplatesampleinthetestequipment,ensurethatthesampleisfirmlyinstalledandhasgoodcontactwiththetestequipmenttosimulatetheactualuseinthebuilding.Heatingprocess:Heatthefurnaceaccordingtothetime-temperaturecurvespecifiedinthestandardtograduallyincreasethetemperatureinthefurnace.Duringtheheatingprocess,thetemperaturechangeofthecolorsteelplateandotherrelatedparametersneedtobemonitoredinrealtime.Observationandrecording:Duringthetest,closelyobservethestateofthecolorsteelplate,includingwhetherthereisdeformation,peeling,cracks,etc.,andrecordthem.Atthesametime,recordthetemperaturechangeoftheback-firesurfaceofthecolorsteelplate,theflamepenetrationandotherinformation.Evaluationindicators:Fireresistancetime:Themostimportantevaluationindicatoristhetimethatthecolorsteelplatecanmaintainitsfireresistanceunderstandardfireconditions.Forthe2-hourfireresistancetest,thecolorsteelplateneedstomaintainitsstructuralintegrityandthermalinsulation(ifapplicable)within2hours,thatis,noseriousdeformation,collapse,flamepenetration,etc.Fireresistanceintegrity:Understandardfireresistancetestconditions,theabilityofbuildingpartitioncomponentstopreventflamesandhotgasfrompenetratingorflamesfromappearingontheback-fires
