一分钟告诉你ISO12952-1跟ISO12952-2阻燃测试有什么差异的

一分钟告诉你ISO12952-1跟ISO12952-2阻燃测试有什么差异的ISO12952-1跟ISO12952-2都是针对床上用品的阻燃测试，标准有相同点，也有不同点，下面分享一下相同点跟不同点。不同点：点火源不同；ISO12952-1是使用闷烧香烟作为点火源的，点燃香烟并使其充分燃烧。ISO12952-2是使用火柴火焰等火源，将其引燃作用于样品上。现象观察不同：ISO12952-1是重点在于检测床上用品在面对闷烧源时的抗燃烧性能，观察是否会出现渐进性焖烧或者产生可检测的烟雾、热量和发光现象。它主要是考虑到一些潜在的、缓慢引发燃烧的情况，像是被未完全熄灭的烟头接触后慢慢燃烧的可能性。ISO12952-2主要是评估床上用品在遭遇相对较强的明火源后的燃烧反应。它要求在移走点火源后，火焰不能持续燃烧超过120秒，并且在移走点火源后的15分钟内，不能有焖烧或产生外部可检测到的烟雾、热量或发光现象。这个标准更侧重于对可能出现的较为明显的火焰接触后的安全性评估。相同点：适用范围相同-床垫覆盖物；-衬垫物；-失禁用被单和衬垫；-被单；-毯子；-电热毯子；-棉被（羽绒被）及其覆盖物；-枕头（包括任何填充物）及垫子；-枕头套。此标准不适用于床垫组合、床体、床衬垫。标准名称：ISO12952-1BurningbehaviourofbeddingItems-smoulderingcigaretteISO12952-2BurningbehaviourofbeddingItems-openflame详情请咨询：中科易朔LetmetellyouthedifferencebetweenISO12952-1andISO12952-2flameretardanttestsinoneminuteDifferences:Differentignitionsources;ISO12952-1usesasmolderingcigaretteasanignitionsource,ignitesthecigaretteandallowsittoburnfully.ISO12952-2usesafiresourcesuchasamatchflametoigniteitonthesample.Differentobservationofphenomena:ISO12952-1focusesontestingtheanti-combustionperformanceofbeddingwhenfacingasmolderingsource,observingwhethertherewillbeprogressivesmolderingordetectablesmoke,heatandluminescence.Itmainlytakesintoaccountsomepotential,slow-initiatingcombustionsituations,suchasthepossibilityofslowcombustionafterbeingcontactedbyanincompletelyextinguishedcigarettebutt.ISO12952-2mainlyevaluatesthecombustionreactionofbeddingafterencounteringarelativelystrongopenflamesource.Itrequiresthataftertheignitionsourceisremoved,theflamecannotcontinuetoburnformorethan120seconds,andwithin15minutesaftertheignitionsourceisremoved,thereshouldbenosmolderingorexternallydetectablesmoke,heatorluminescence.Thisstandardfocusesmoreonthesafetyassessmentofmoreobviousflameexposurethatmayoccur.Similarities:Samescopeofapplication-Mattresscovers;-Cushions;-Incontinencesheetsandpads;-Sheets;-Blankets;-Electricblankets;-Quilts(duvets)andtheircovers;-Pillows(includinganyfi
