一分鐘了解下防火門申請(qǐng)AS1530.4耐火測(cè)試注意事項(xiàng)什么是防火門？防火門是指在一定時(shí)間內(nèi)能滿足耐火穩(wěn)定性、完整性和隔熱性要求的門，由消防部經(jīng)濟(jì)部指定認(rèn)可實(shí)驗(yàn)室，根據(jù)相關(guān)國家標(biāo)準(zhǔn)防火門耐火試驗(yàn)法測(cè)試合格，并取得相應(yīng)驗(yàn)證登錄證書及授權(quán)標(biāo)識(shí)者，才能稱之為防火門。防火門按耐火性能分類:隔熱防火門（A類）：耐火隔熱性和耐火完整性同時(shí)滿足相應(yīng)時(shí)間要求，如耐火隔熱性≥0.50h，耐火完整性≥0.50h的為A0.50（丙級(jí)）；耐火隔熱性≥1.00h，耐火完整性≥1.00h的為A1.00（乙級(jí)）；耐火隔熱性≥1.50h，耐火完整性≥1.50h的為A1.50（甲級(jí)）等。部分隔熱防火門（B類）：耐火隔熱性≥0.50h，耐火完整性滿足相應(yīng)時(shí)間要求，如耐火完整性≥1.00h的為B1.00；耐火完整性≥1.50h的為B1.50等。非隔熱防火門（C類）：僅滿足耐火完整性要求，如耐火完整性≥1.00h的為C1.00；耐火完整性≥1.50h的為C1.50等。防火門分類：木質(zhì)防火門，鋼質(zhì)防火門，鋼木質(zhì)防火門，其他材質(zhì)防火門。AS1530.4耐火測(cè)試簡(jiǎn)介：標(biāo)準(zhǔn)名稱：AS/NZS1530.4：建筑材料、元件和構(gòu)件的防火測(cè)試-第4部分：建筑物單元耐燃測(cè)試AS/NZS1530.4：Methodsforfiretestsonbuildingmaterials,componentsandstructures-Fire-resistancetestofelementsofconstruction判定依據(jù)：失去完整性：當(dāng)棉墊被點(diǎn)燃或者背火面燃燒達(dá)10秒鐘以上時(shí)，被認(rèn)為試件失去完整性；測(cè)試過程中，6mm直徑的探棒可穿過裂縫進(jìn)入爐內(nèi)且探棒可沿裂縫長(zhǎng)度方向不小于150mm；直徑25mm的探棒可穿過裂縫進(jìn)入爐內(nèi)時(shí)，則被認(rèn)為試件失去完整性。失去隔熱性：試件背火面的平均溫升超過試件表面初始平均溫度140℃或者背火面在任何一點(diǎn)的溫升超過該點(diǎn)初始溫度180℃時(shí)，則被認(rèn)為試件失去隔熱性。綜上總結(jié)，AS1530.4判定依據(jù)有完整性跟隔熱性，防火門做AS1530.4耐火測(cè)試，特別要注意的是隔熱性能，需要特別注意。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
