Hauv peb lub ntiaj teb niaj hnub no, cov khoom siv hluav taws xob muaj nyob txhua qhov chaw, los ntawm cov xov tooj smartphones mus rau cov khoom siv ntse, los ntawm cov khoom siv rau cov khoom siv tsheb.Nrog rau kev siv dav dav, nws dhau los ua qhov tseem ceeb los xyuas kom meej tias cov cuab yeej no tuaj yeem tiv taus ntau yam ib puag ncig.Nov yog qhov chaw kuaj IPx tuaj rau hauv kev ua si.

IPx test chambers, tseem hu ua ingress Protection test chambers, yog cov cuab yeej tshwj xeeb kuaj tsim los ntsuas cov qib ntawm kev tiv thaiv los ntawm cov khoom tiv thaiv kev nkag ntawm cov khoom thiab cov kua dej.IPx rating system, txhais los ntawm International Electrotechnical Commission (IEC), faib cov qib kev tiv thaiv los ntawm ib lub cuab yeej.

Tus "IP" hauv IPx sawv cev rau "Ingress Protection," thiab "x" yog hloov los ntawm ob tus lej uas sawv cev rau qib kev tiv thaiv.Thawj tus lej yog nyob ntawm 0 txog 6 thiab qhia txog qib ntawm kev tiv thaiv cov khoom siv, thaum tus lej thib ob nyob ntawm 0 txog 9 thiab qhia txog qib kev tiv thaiv cov kua.

IPx test chambers simulate cov xwm txheej hauv ntiaj teb los ntsuas cov cuab yeej tiv thaiv plua plav, dej, thiab lwm yam khoom uas muaj teeb meem.Cov chav no muaj cov kev tswj xyuas qhov tseeb los kho ib puag ncig yam xws li qhov kub thiab txias, av noo, thiab cov dej ntws, tso cai rau kev ntsuas kom raug thoob plaws ntau yam kev mob.

Thaum lub sij hawm kuaj, cov cuab yeej nyob rau hauv kev ntsuam xyuas yog raug rau ntau theem ntawm cov khoom particle intrusion thiab kua ingress, raws li qhov xav tau kev ntsuam xyuas IP.Piv txwv li, yog tias ib lub cuab yeej npaj los ua dej-resistant, nws yuav raug kuaj nrog kev nce qib siab ntawm cov dej siab thiab lub sij hawm raug.

IPx test Chambers ua lub luag haujlwm tseem ceeb hauv kev tsim khoom thiab kev tswj kom zoo.Cov neeg tsim khoom tuaj yeem soj ntsuam thiab txhim kho lawv cov khoom tsim kom tau raws li qhov kev ntsuas IP tshwj xeeb rau kev siv sib txawv.Los ntawm cov neeg siv khoom siv hluav taws xob mus rau cov khoom siv sab nraum zoov, cov chav no muab cov ntaub ntawv tseem ceeb los xyuas kom cov khoom muaj zog txaus los tiv thaiv lawv qhov chaw nyob.

Tsis tas li ntawd, cov chav kuaj IPx pab ua raws li cov qauv kev lag luam thiab cov kev cai tswj hwm.Cov ntawv pov thawj raws li kev ntsuam xyuas IP feem ntau yuav tsum tau ua rau qee yam khoom, xws li cov khoom siv kho mob lossis cov khoom siv hluav taws xob siv nyob rau hauv qhov chaw muaj kev phom sij.Los ntawm kev siv cov chav kuaj IPx, cov tuam txhab lag luam tuaj yeem ua kom pom kev ntseeg tau thiab ua haujlwm ntev ntawm lawv cov khoom, txhawb kev ntseeg siab rau cov neeg siv khoom thiab cov tswj hwm lub cev.

Hauv kev xaus, IPx cov chav kuaj sim yog cov cuab yeej tseem ceeb rau kev ntsuas qhov kev tiv thaiv ingress ntawm cov khoom siv hluav taws xob.Los ntawm kev muab cov khoom siv rau kev sim nruj hauv kev simulated ib puag ncig, cov tuam ntxhab tuaj yeem ua kom lawv cov cuab yeej tiv taus plua plav, dej, thiab lwm yam khoom sab nraud.Nrog IPx kev ntsuam xyuas thiab ntawv pov thawj, cov neeg siv khoom tuaj yeem txiav txim siab paub, paub tias cov khoom uas lawv xaiv tau dhau los ua kev sim thiab ua tau raws li cov qauv kev lag luam.
