一篇關(guān)于ASTME1354產(chǎn)品熱釋放速率的分享文ASTME1354熱釋放適用范圍：本防火測(cè)試應(yīng)用標(biāo)準(zhǔn)用于測(cè)量暴露在有或沒(méi)有外部點(diǎn)火器的受控輻射熱水平下的材料的狀況。ASTME1354測(cè)試數(shù)據(jù)：該測(cè)試方法用于確定材料和產(chǎn)品的可燃性、放熱率、質(zhì)量損失率、燃燒熱釋放和可見(jiàn)煙產(chǎn)生。ASTME1354數(shù)據(jù)影響因素：熱釋放速率是由氧的濃度和廢氣流的流量決定的耗氧量的測(cè)量來(lái)決定的。有效燃燒熱的測(cè)定是根據(jù)測(cè)量標(biāo)本質(zhì)量損失率,在結(jié)合國(guó)家的熱釋放率。煙霧大大小是通過(guò)燃燒產(chǎn)物流對(duì)光的遮蔽來(lái)測(cè)量的。ATSME1354測(cè)試原理：試樣應(yīng)暴露在0-100kw/m2范圍內(nèi)的初始測(cè)試熱流。使用外部點(diǎn)火時(shí)，應(yīng)采用電火花點(diǎn)火。初始測(cè)試熱流的值和外部點(diǎn)火的使用應(yīng)按照相關(guān)材料或性能標(biāo)準(zhǔn)的規(guī)定(見(jiàn)X1.2)。正常的試樣測(cè)試方向是水平的，與最終使用應(yīng)用是水平方向還是垂直方向無(wú)關(guān)。該裝置還包含用于垂直方向測(cè)試的規(guī)定;這只用于探索性或診斷性研究。ATSME1354標(biāo)準(zhǔn)名稱(chēng)：ASTME1354MethodoftestforheatandsmokereleaseratesformaterialsandproductsusinganOxygenConsumptionCalorimeterASTME1354耗氧量法測(cè)定材料釋熱及煙霧釋放速率方法耗氧量法測(cè)定材料釋熱的意義：這種測(cè)試方法主要用于確定在涉及測(cè)試材料產(chǎn)品的火災(zāi)中演化或促成的熱量。還包括確定燃燒的有效熱量、質(zhì)量損失率、持續(xù)燃燒的時(shí)間和煙霧產(chǎn)生。這些性質(zhì)是在小尺寸的樣品上確定的，這些樣品代表了預(yù)期的最終用途。AsharingarticleaboutASTME1354productheatreleaserateASTME1354HeatReleaseScope:Thisfiretestapplicationstandardisusedtomeasuretheconditionofmaterialsexposedtocontrolledradiantheatlevelswithorwithoutanexternaligniter.ASTME1354TestData:Thistestmethodisusedtodeterminetheflammability,heatreleaserate,masslossrate,combustionheatrelease,andvisiblesmokeproductionofmaterialsandproducts.ASTME1354DataInfluencingFactors:Theheatreleaserateisdeterminedbymeasuringtheoxygenconsumptiondeterminedbytheoxygenconcentrationandtheflowrateoftheexhaustgasstream.Theeffectiveheatofcombustionisdeterminedbymeasuringthespecimenmasslossrate,incombinationwiththestateoftheheatreleaserate.Thesmokesizeismeasuredbytheobstructionoflightbythecombustionproductstream.ATSME1354TestPrinciple:Thespecimenshallbeexposedtoaninitialtestheatfluxintherangeof0-100kW/m2.Whenexternalignitionisused,electricsparkignitionshallbeused.Thevalueoftheinitialtestheatfluxandtheuseofexternalignitionshallbeasspecifiedintherelevantmaterialorperformancestandard(seeX1.2).Thenormalspecimentestingorientationishorizontal,regardlessofwhethertheend-useapplicationishorizontalorvertical.Theunitalsocontainsprovisionsfortestingintheverticalorientation;thisisonlyintendedforexploratoryordiagnosticstudies.ATSME1354StandardName：ASTME1354MethodoftestforheatandsmokereleaseratesformaterialsandproductsusinganOxygenConsumptionCalorimeterSignificanceofheatreleaseofmaterialsbyoxygenconsumptionmethod:Thistestmethodismainlyusedtodeterminetheheatdevelopedorcontributedtoinafireinvolvingthetestmaterialproduct.Italsoincludesdeterminingtheeffectiveheatofcombustion,masslossrate,durationofcontinu
