一分钟了解下防火门申请AS1530.4耐火测试注意事项

一分钟了解下防火门申请AS1530.4耐火测试注意事项什么是防火门？防火门是指在一定时间内能满足耐火稳定性、完整性和隔热性要求的门，由消防部经济部指定认可实验室，根据相关国家标准防火门耐火试验法测试合格，并取得相应验证登录证书及授权标识者，才能称之为防火门。防火门按耐火性能分类:隔热防火门（A类）：耐火隔热性和耐火完整性同时满足相应时间要求，如耐火隔热性≥0.50h，耐火完整性≥0.50h的为A0.50（丙级）；耐火隔热性≥1.00h，耐火完整性≥1.00h的为A1.00（乙级）；耐火隔热性≥1.50h，耐火完整性≥1.50h的为A1.50（甲级）等。部分隔热防火门（B类）：耐火隔热性≥0.50h，耐火完整性满足相应时间要求，如耐火完整性≥1.00h的为B1.00；耐火完整性≥1.50h的为B1.50等。非隔热防火门（C类）：仅满足耐火完整性要求，如耐火完整性≥1.00h的为C1.00；耐火完整性≥1.50h的为C1.50等。防火门分类：木质防火门，钢质防火门，钢木质防火门，其他材质防火门。AS1530.4耐火测试简介：标准名称：AS/NZS1530.4：建筑材料、元件和构件的防火测试-第4部分：建筑物单元耐燃测试AS/NZS1530.4：Methodsforfiretestsonbuildingmaterials,componentsandstructures-Fire-resistancetestofelementsofconstruction判定依据：失去完整性：当棉垫被点燃或者背火面燃烧达10秒钟以上时，被认为试件失去完整性；测试过程中，6mm直径的探棒可穿过裂缝进入炉内且探棒可沿裂缝长度方向不小于150mm；直径25mm的探棒可穿过裂缝进入炉内时，则被认为试件失去完整性。失去隔热性：试件背火面的平均温升超过试件表面初始平均温度140℃或者背火面在任何一点的温升超过该点初始温度180℃时，则被认为试件失去隔热性。综上总结，AS1530.4判定依据有完整性跟隔热性，防火门做AS1530.4耐火测试，特别要注意的是隔热性能，需要特别注意。LearnabouttheprecautionsforapplyingforAS1530.4fireresistancetestforfiredoorsinoneminuteWhatisafiredoor?Afiredoorisadoorthatcanmeettherequirementsoffireresistancestability,integrityandthermalinsulationwithinacertainperiodoftime.ItcanonlybecalledafiredoorifitistestedbyalaboratorydesignatedbytheMinistryofFireandtheMinistryofEconomicAffairsaccordingtothefireresistancetestmethodofrelevantnationalstandardsandobtainsthecorrespondingverificationregistrationcertificateandauthorizedlogo.Firedoorsareclassifiedaccordingtofireresistanceperformance:Insulatedfiredoors(ClassA):Fireresistanceinsulationandfireresistanceintegritymeetthecorrespondingtimerequirementsatthesametime,suchasfireresistanceinsulation≥0.50h,fireresistanceintegrity≥0.50hisA0.50(ClassC);fireresistanceinsulation≥1.00h,fireresistanceintegrity≥1.00hisA1.00(ClassB);fireresistanceinsulation≥1.50h,fireresistanceintegrity≥1.50hisA1.50(ClassA),etc.Partiallyinsulatedfiredoors(ClassB):Fireinsulation≥0.50h,fireintegritymeetsthecorrespondingtimerequirements,suchasfireintegrity≥1.00hisB1.00;fireintegrity≥1.50hisB1.50,etc.Non-insulatedfiredoors(ClassC):Onlymeetthefireintegrityrequirements,suchasfireintegrity≥1.00hisC1.00;fireintegrity≥1.50hisC1.50,etc.Firedoorclassification:Woodenfiredoors,steelfiredoors,steel-woodfiredoors,othermaterialsfiredoors.AS1530.4FireTestIntroduction:1.StandardName:AS/NZS1530.4:Methodsforfiretestsonbuildingmaterials,componentsandstructures-Fire-resistancetestofelementsofconstruction2.JudgmentBasis:Lossofintegrity:Whenthecottonpadisignitedorthebackfiresurfaceburnsformorethan10seconds,thespecimenisconsideredtohavelostitsintegrity;Duringthetest,a6mmdiameterprobecanpassthroughthecrackintothefurnaceandtheprobecanbenolessthan150mmalongthelengthofthecrack;Whena25mmdiameterprobecanpassthroughthecrackintothefurnace,thespecimenisconsideredtohavelostitsintegrity.Lossofthermalinsulation:Whentheaveragetemperatureriseofthebackfiresurfaceofthespecimenexceedstheinitialaveragetemperatureofthespecimensurfaceby140℃orthetemperatureriseofthebackfiresurfaceatanypointexceedstheinitialtemperatureofthatpointby180℃,thespecimenisconsideredtohavelostitsthermalinsulation.Insummary,theAS1530.4
