Txhawm rau muag cov khoom siv hluav taws xob hauv European kev ua lag luam, cov khoom lag luam yuav tsum ua raws li cov txheej txheem kev nyab xeeb thiab kev ua tau zoo ntawm cov ntawv pov thawj kom ntseeg tau tias muaj kev tiv thaiv zoo thaum muaj xwm txheej ceev. Ib qho ntawm cov ntawv pov thawj tseem ceeb tshaj plaws yogTS EN 14604.
kuj koj tuaj yeem tshawb xyuas ntawm no, CFPA-EU: Muab cov lus piav qhia ntawmcov kev cai rau pa taws tswb nyob teb chaws Europe.
1. EN 14604 Daim ntawv pov thawj
EN 14604 yog ib qho yuav tsum muaj ntawv pov thawj tus qauv hauv Tebchaws Europe tshwj xeeb rau cov khoom siv hluav taws xob hauv tsev. Cov txheej txheem no qhia txog kev tsim, tsim khoom, thiab kev sim ntsuas kom ntseeg tau tias lub cuab yeej tuaj yeem ntes cov pa taws sai thiab teeb tsa lub tswb thaum muaj hluav taws.
Daim ntawv pov thawj EN 14604 suav nrog ntau yam tseem ceeb:
- Teb Sijhawm: Cov pa luam yeeb yuav tsum teb sai sai thaum cov pa luam yeeb nce mus txog qib txaus ntshai.
- Tswb Volume: Lub cuab yeej lub tswb yuav tsum ncav cuag 85 decibels, kom ntseeg tau tias cov neeg nyob hauv tuaj yeem hnov nws.
- False Alarm Rate: Tus ntes yuav tsum muaj tus nqi qis ntawm lub tswb cuav kom tsis txhob muaj kev cuam tshuam tsis tsim nyog.
- DurabilityTS EN 14604 kuj tseem qhia txog kev ua haujlwm ntev, suav nrog kev tiv thaiv kev vibrations, electromagnetic cuam tshuam, thiab lwm yam sab nraud.
EN 14604 yog ib qho tseem ceeb rau kev nkag mus rau European lag luam. Hauv cov teb chaws xws li UK, Fabkis, thiab lub teb chaws Yelemees, cov tsev nyob thiab cov tsev lag luam yuav tsum tau teeb tsa lub tshuab ntsuas pa taws ua tau raws li EN 14604 tus qauv los tiv thaiv cov neeg nyob hauv kev nyab xeeb.
2. Daim ntawv pov thawj CE
Ntxiv rau EN 14604, cov pa luam yeeb kuj xav tauCE daim ntawv pov thawj. CE cim qhia tias ib yam khoom ua raws li kev noj qab haus huv, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig hauv European Union. Cov pa luam yeeb nrog daim ntawv pov thawj CE qhia tias ua raws li cov kev cai tseem ceeb thoob plaws European Economic Area (EEA). CE daim ntawv pov thawj feem ntau tsom rau electromagnetic compatibility thiab cov lus qhia tsis tshua muaj hluav taws xob los xyuas kom meej tias cov cuab yeej ua haujlwm zoo hauv ntau qhov chaw hluav taws xob.
3. Daim ntawv pov thawj RoHS
Teb chaws Europe kuj muaj cov kev cai nruj heev txog cov khoom phom sij hauv cov khoom.RoHS ntawv pov thawj(Kev txwv tsis pub muaj phom sij) txwv tsis pub siv cov khoom siv phom sij tshwj xeeb hauv cov khoom siv hluav taws xob. Daim ntawv pov thawj RoHS txwv tsis pub muaj cov hmoov txhuas, mercury, cadmium, thiab lwm yam khoom hauv cov pa luam yeeb, ua kom muaj kev nyab xeeb ntawm ib puag ncig thiab kev noj qab haus huv ntawm cov neeg siv.
Lub roj teeb yuav tsum muaj rau cov pa luam yeeb hauv Europe
Ntxiv nrog rau cov ntawv pov thawj, muaj cov kev cai tshwj xeeb hais txog cov roj teeb ntsuas hluav taws xob hauv Tebchaws Europe, tshwj xeeb yog tsom rau kev ruaj khov thiab kev saib xyuas qis. Raws li cov kev cai rau cov tsev nyob thiab kev lag luam, cov roj teeb sib txawv cuam tshuam rau cov cuab yeej tsim nyog thiab lub neej ntev.
1. Lub neej ntev Lithium roj teeb
Nyob rau hauv xyoo tas los no, European lag luam tau nce mus rau lub neej ntev roj teeb, tshwj xeeb tshaj yog cov roj teeb lithium uas tsis tuaj yeem hloov tau. Feem ntau, cov roj teeb lithium muaj lub neej ntev txog li 10 xyoo, sib piv cov kev hloov pauv hloov pauv rau cov ntsuas pa taws. Lub neej ntev lithium roj teeb muaj ntau yam txiaj ntsig:
- Kev kho qis:Cov neeg siv tsis tas yuav nquag hloov roj teeb, txo cov nqi kho.
- Environmental Benefits:Kev hloov roj teeb tsawg dua ua rau cov khoom siv hluav taws xob tsawg dua.
- Kev nyab xeeb:Cov roj teeb lithium ntev ntev txo cov kev pheej hmoo cuam tshuam nrog cov roj teeb tsis ua haujlwm lossis cov nqi qis.
Qee lub tebchaws nyob sab Europe txawm xav tau kev txhim kho lub tsev tshiab kom muaj cov khoom siv hluav taws xob uas tsis tuaj yeem hloov tau, 10-xyoo lub neej ntev roj teeb los xyuas kom muaj zog ruaj khov thoob plaws hauv lub neej voj voog.
2. Cov roj teeb hloov tau nrog lub tswb ceeb toom
Rau cov khoom siv uas siv cov roj teeb hloov tau, cov qauv European xav kom cov cuab yeej muab cov lus ceeb toom meej meej thaum lub roj teeb muaj zog, ua rau cov neeg siv hloov lub roj teeb tam sim. Feem ntau, cov khoom siv no siv cov qauv 9V alkaline lossis AA roj teeb, uas tuaj yeem nyob ib puag ncig ib mus rau ob xyoos, ua rau lawv tsim nyog rau cov neeg siv khoom uas nyiam cov nqi roj teeb qis dua.
3. Hom roj teeb txuag hluav taws xob
Txhawm rau ua kom tau raws li European kev lag luam qhov kev thov rau kev siv hluav taws xob, qee lub tshuab nqus pa ua haujlwm nyob rau hauv hom qis zog thaum tsis muaj xwm txheej ceev, txuas ntxiv roj teeb lub neej. Tsis tas li ntawd, qee cov khoom siv hluav taws xob ntse muaj lub zog txuag hluav taws xob thaum hmo ntuj uas txo qis kev siv hluav taws xob los ntawm kev saib xyuas tsis tu ncua, thaum tseem ua kom cov lus teb ceev ceev thaum muaj pa taws.
Xaus
Kev muag cov khoom siv hluav taws xob hauv European lag luam yuav tsum ua raws li cov ntawv pov thawj zoo li EN 14604, CE, thiab RoHS kom lav cov khoom muaj kev nyab xeeb, kev ntseeg siab, thiab kev phooj ywg ib puag ncig. Cov pa luam yeeb ntes nrog lub neej ntev lithium roj teeb tau nrov dua nyob rau hauv Tebchaws Europe, ua raws cov qauv rau kev saib xyuas qis thiab kev ruaj ntseg ib puag ncig. Rau cov khoom lag luam nkag mus rau European kev ua lag luam, kev nkag siab thiab ua raws li cov ntawv pov thawj no thiab cov roj teeb uas yuav tsum tau ua yog qhov tseem ceeb los muab cov khoom lag luam ua raws thiab ua kom muaj kev nyab xeeb.
