CANCGSB-182.1 垂直測試與水平測試的區(qū)別解析

CAN/CGSB-182.1垂直測試與水平測試的區(qū)別解析CANCGSB-182.1是加拿大通用標(biāo)準(zhǔn)委員會(huì)（CGSB）發(fā)布的《帳篷易燃性和標(biāo)簽要求》標(biāo)準(zhǔn)，主要針對(duì)戶外帳篷材料的阻燃性能評(píng)估。其中，垂直測試和水平測試是該標(biāo)準(zhǔn)中兩種核心的燃燒測試方法。適用范圍：CANCGSB-182.1標(biāo)準(zhǔn)適用于露營帳篷、遮陽棚和類似露營帳篷或其他遮蔽物的游樂帳篷等。主要評(píng)估帳篷材料在三種狀態(tài)（未處理、浸漬后和老化后）下暴露于火焰時(shí)的可燃性。測試對(duì)象不同：垂直測試：針對(duì)所有材料，帳篷材料的強(qiáng)制性測試，包括墻面、頂部及地板材料水平測試：僅針對(duì)地板材料測試方法與環(huán)境預(yù)處理不同垂直測試：使用燃燒器火焰（火焰高度38mm，持續(xù)12秒）。測試時(shí)，材料需在垂直方向固定，火焰從底部施加，模擬帳篷側(cè)面或頂部材料受火源影響的場景。水平測試：甲醇胺片引燃（模擬實(shí)際火源）。測試時(shí)，材料水平放置，火焰施加于表面，模擬地板接觸火源（如篝火余燼）的情況。其核心目標(biāo)是評(píng)估地板材料在水平方向上的阻燃能力，防止火焰橫向蔓延。判定標(biāo)準(zhǔn)不同垂直測試：燃燒損壞長度≤規(guī)定閾值；質(zhì)量損失≤規(guī)定閾值；

此外，燃燒碎屑的脫落量需嚴(yán)格受限，以避免引發(fā)二次火災(zāi)水平測試：水平測試的判定標(biāo)準(zhǔn)相對(duì)寬松，主要關(guān)注火焰是否在限定時(shí)間內(nèi)自熄，以及燃燒范圍是否可控。即使垂直測試失敗，若地板材料通過水平測試，仍可被認(rèn)定為符合標(biāo)準(zhǔn)AnalysisoftheDifferencesbetweenVerticalandHorizontalTestinginCAN/CGSB-182.1CANCGSB-182.1isthe"FlammabilityandLabelingRequirementsforTent"standardpublishedbytheCanadianGeneralStandardsBoard(CGSB),mainlyaimedatevaluatingtheflameretardantperformanceofoutdoortentmaterials.Amongthem,verticaltestingandhorizontaltestingarethetwocorecombustiontestingmethodsinthisstandard.Scopeofapplication:TheCANCGSB-182.1standardisapplicabletocampingtents,sunshades,andsimilarcampingtentsorothersheltersforrecreationalpurposes.Themainevaluationistheflammabilityoftentmaterialswhenexposedtoflamesinthreestates(untreated,impregnated,andaged).Differenttestobjects:Verticaltesting:mandatorytestingforallmaterials,includingwall,roof,andfloormaterials,fortentmaterialsLeveltest:onlyapplicabletoflooringmaterialsDifferenttestingmethodsandenvironmentalpreprocessingVerticaltest:Useaburnerflame(flameheight38mm,duration12seconds).Duringtesting,thematerialneedstobefixedintheverticaldirection,andtheflameshouldbeappliedfromthebottom,simulatingthescenewherethematerialonthesideortopofthetentisaffectedbyafiresource.Leveltest:Methanolaminetabletignition(simulatingactualfiresource).Duringtesting,thematerialisplacedhorizontallyandflamesareappliedtothesurface,simulatingthesituationwherethefloorcomesintocontactwithafiresource(suchasembersfromacampfire).Thecoreobjectiveistoevaluatetheflameretardantabilityofflooringmaterialsinthehorizontaldirectionandpreventthelateralspreadofflames.DifferentcriteriaforjudgmentVerticaltesting:Burningdamagelength≤specifiedthreshold;Qualityloss≤specifiedthreshold;Inaddition,theamountofdebrisshedduringcombustionmustbestrictlylimitedtoavoidtriggeringasecondaryfireLeveltest:Thecriteriafordeterminingproficiencytestingarerelativelyloose,mainlyfocusingonwhethertheflameextinguishesitselfwithinalimitedtimeandwhetherthecombustionrangeiscontrollabl
