自净时间测试

1.1RecoveryTime自净时间Purpose目的Verifythattheroomcleanlinessrecoverytimeinhowlong,canreachtherequirements.确认房间洁净度自净时间在多长时间内，能够达到规定的要求。Procedure程序1.Laytheparticlecounterintheassignationposition;在给定位置上放置颗粒计数器；2.Accordingtotheoutletarrangementoftheroom,setthemeasurementpointinthetheoryofself-purificationlongestarea;根据房间风口布置情况，在理论自净时间最长的区域设置测量点。3.Thenumberofmeasurementpointsdependsonthevolumeoftheroomtovalidate;测量点的数量按照房间的体积来确定；Volumeoftheroom(m3)房间的容积(m3)Numberofmeasurementpoints测量点的数量V75175≤V1502150≤V2253V≥22544.Inpourintotheparticleintheroominuseofthesmokegenerator;在使用发烟器的情况下，在房间内注入颗粒；-Openthesmokegenerator;开启发烟器；-Inpourintothesmogintheroom,thesmogmaynotinpourintotheplacetooapproachesthesoundingset;往房间注入烟雾；烟雾不可以注入得过于接近探测仪；-Diffusethesmogbythemovementofthehand;以手掌运动扩散烟雾；5.Starttheparticlecalculating(turnontheparticlecounteratonetime);开始颗粒计算（同时打开颗粒计数器）；Frequency：Recorditeachminute;频率：每分钟记录一次；Thesizeoftheparticle≥0.5μm;颗粒大小≥0.5μm；6.Recordtheconcentrationofinitialparticles(C0);记录初始颗粒浓度(C0)；7.Recordofparticleconcentrationinaminute(C1);记录一分钟后的颗粒浓度(C1)；8.Usethefollowingformulatocalculatecleanlinessrecoveryrate;使用下列公式计算洁净度恢复率；-n--cleanlinessrecoveryrate;n--洁净度恢复率；-t1--Twomeasuringtimeinterval;01101log13.2nCCtt1--第一次和第二次测量的间隔时间；-C0--Concentrationofinitialparticles;C0--最初浓度；-C1--Concentrationofthetimeafterthet1;C1--时间t1后的浓度；C1=C0exp(-nt1)9.Thetestcycletestfivetimes,taketheaveragerecoveryrate;一个测试点循环测试5次，取恢复率平均值；nx=(n1+n2+n3……)/x10.Therecoveryrateofcleanlinessand100:1recoverytimerelationshipisasfollows;洁净度恢复率值与100：1自净时间两者关系如下：11.Accordingtotherecoveryrateofcleanlinessvaluecalculated100:1recoverytime.根据洁净度恢复率值计算得出100：1自净时间。AcceptanceCriteria可接受标准Theactualrecoverytimeofeachsamplepointofeachroomisnotmorethanitsstandardrecoverytime(15min).所有房间内取样点的自净时间不大于标准自净时间15分钟。Theprimitiveprintingreportisattachedtothisprotocol.原始打印报告附在本方案中。Result结果FillinForm10.Whererequirementsresults“NotApplicable”fillthecellwithN.A.andexplaintherelevantreasonwithinthe“Note”section.填写表10。如果要求不适用，填写“N.A.”，并在备注栏中注明原因。Recordingnonconformityoccurredduringtheexecutiononthedeviationreport.在偏差报告中记录在实施过程中所发生的不符合项。01.001.016.41001log13.210ttnForm表10RecoveryTimeTest自净时间的测试RoomNo.房间号Roomname房间名称Class洁净级别SamplePoint测试点Testnumber测试次数Theinitialparticle初始颗粒浓度（C0）(个/m3)Theparticleconcentrationinaminute一分钟后颗粒浓度（C1）(个/m3)Log10(C1/C0)以10为底的(C1/C0)对数ActualRecoveryTime实际自净时间(min)AverageRecoveryTime平均自净时间（min）Conformed?符合?Yes是/No否15011限度室（一）C11234515013限度室（二）C112345RoomNo.房间号Roomname房间名称Class洁净级别SamplePoint测试点Testnumber测试次数Theinitialparticle初始颗粒浓度（C0）(个/m3)Theparticleconcentrationinaminute一分钟后颗粒浓度（C1）(个/m3)C1/C0C1与C0之比Log10(C1/C0)以10为底的(C1/C0)对数ActualRecoveryTime实际自净时间(min)AverageRecoveryTime平均自净时间（min）Conformed?符合?Yes是/No否15015阳性对照室C112345AcceptanceCriteria可接受的标准Yes是/No否Recoverytimeofallroomattainedrequirement.所有房间的自净时间达到要求。Theprimitiveprintingreportisattachedtothisprotocol.所有的原始打印报告附在本方案中。Samplelayoutisattachedtothisprotocol.附上测试点分布图。Note备注:Executedby执行人Date日期(yyyy.mm.dd)Repeatedby复核人Date日期(yyyy.mm.dd)
