▍ Daim ntawv pov thawj CE yog dab tsi?
Lub cim CE yog "passport" rau cov khoom lag luam nkag mus rau EU kev lag luam thiab EU Free Trade Association lub teb chaws ua lag luam.Cov khoom lag luam uas tau teev tseg (suav nrog cov lus qhia tshiab), txawm tias tsim tawm sab nraud EU lossis hauv EU cov tswvcuab hauv lub tebchaws, txhawm rau txhawm rau nthuav dav hauv EU kev lag luam, lawv yuav tsum ua raws li cov cai ntawm cov lus qhia thiab cov qauv kev sib haum xeeb ua ntej. muab tso rau hauv EU ua lag luam, thiab affix CE cim.Qhov no yog qhov yuav tsum tau ua ntawm EU txoj cai lij choj ntawm cov khoom muaj feem xyuam, uas muab cov txheej txheem kev sib koom ua ke yam tsawg kawg nkaus rau kev lag luam ntawm ntau lub teb chaws hauv European kev ua lag luam thiab ua kom yooj yim cov txheej txheem kev lag luam.
▍ Cov lus qhia CE yog dab tsi?
Cov lus qhia yog ib daim ntawv pov thawj tsim los ntawm European Community Council thiab European Commission raws li kev tso cai ntawmEuropean Community Treaty.Cov lus qhia siv tau rau cov roj teeb yog:
2006/66 / EC & 2013/56 / EU: Roj Teeb Cov Lus Qhia.Cov roj teeb uas ua raws li cov lus qhia no yuav tsum muaj lub thoob khib nyiab pov tseg;
2014/30 / EU: Electromagnetic Compatibility Directive (EMC Cov Lus Qhia).Cov roj teeb uas ua raws li cov lus qhia no yuav tsum muaj CE cim;
2011/65 / EU: ROHS cov lus qhia.Cov roj teeb uas ua raws li cov lus qhia no yuav tsum muaj CE cim;
Cov Lus Qhia: Tsuas yog thaum cov khoom ua raws li tag nrho cov lus qhia CE (CE cim yuav tsum tau muab tso rau), tuaj yeem muab CE kos rau thaum tag nrho cov kev cai ntawm cov lus qhia tau ua tiav.
▍ Qhov Tseem Ceeb ntawm Kev Thov rau CE Certification
Txhua yam khoom los ntawm ntau lub teb chaws uas xav nkag mus rau EU thiab European Free Trade Zone yuav tsum thov rau CE-certified thiab CE cim rau ntawm cov khoom.Yog li, daim ntawv pov thawj CE yog daim ntawv hla tebchaws rau cov khoom nkag mus rau EU thiab European Free Trade Zone.
▍ Cov txiaj ntsig ntawm kev thov rau daim ntawv pov thawj CE
1. EU txoj cai lij choj, kev tswj hwm, thiab cov qauv kev sib koom tes tsis yog tsuas yog loj ntawm cov khoom, tab sis kuj nyuaj hauv cov ntsiab lus.Yog li ntawd, tau txais daim ntawv pov thawj CE yog ib qho kev xaiv ntse heev kom txuag tau lub sijhawm thiab kev siv zog thiab txo qhov kev pheej hmoo;
2. Daim ntawv pov thawj CE tuaj yeem pab kom tau txais kev ntseeg siab ntawm cov neeg siv khoom thiab lub koom haum saib xyuas kev lag luam mus rau qhov siab tshaj plaws;
3. Nws tuaj yeem tiv thaiv qhov xwm txheej tsis lees paub;
4. Nyob rau hauv lub ntsej muag ntawm kev sib hais plaub, daim ntawv pov thawj CE yuav dhau los ua pov thawj raug cai;
5. Thaum raug txim los ntawm EU lub teb chaws, lub koom haum muab ntawv pov thawj yuav koom tes nrog cov kev pheej hmoo ntawm kev lag luam, yog li txo qhov kev pheej hmoo ntawm kev lag luam.
▍ Vim li cas MCM?
● MCM muaj ib pab neeg ua haujlwm nrog ntau tshaj 20 tus kws tshaj lij ua haujlwm hauv kev ua haujlwm ntawm cov roj teeb CE daim ntawv pov thawj, uas muab cov neeg siv khoom sai dua thiab raug thiab cov ntaub ntawv pov thawj CE tshiab kawg;
● MCM muab ntau yam kev daws teeb meem CE suav nrog LVD, EMC, cov lus qhia roj teeb, thiab lwm yam rau cov neeg siv khoom;
● MCM tau muab ntau tshaj 4000 roj teeb CE kuaj thoob ntiaj teb txog niaj hnub no.
Thaum Lub Kaum Ib Hlis 27, 2023, "UN Manual of Tests and Criteria" (Rev. 8) tau tshaj tawm hauv Tebchaws Meskas lub vev xaib."UN Manual of Tests and Criteria" (Tshwm Sim 8) lees txais cov kev hloov kho uas tau ua los ntawm 11th lub rooj sib tham ntawm United Nations TDG thiab GHS Cov Kws Tshaj Lij Pabcuam ntawm "UN Manual of Tests and Criteria" (Rev. 7) thiab nws Cov Kev Hloov Kho 1 . Raws li qhov kev sim yooj yim rau kev thauj mus los ntawm kev nyab xeeb roj teeb, "UN Manual of Tests and Criteria" (Rev. 8) tau ntxiv ib ntu tshiab ntawm 38.3.3.2 "Kev ntsuam xyuas ntawm sodium ion hlwb thiab roj teeb", thiab ib txhij ntxiv cov khoom tshwj xeeb uas muaj feem xyuam rau. Sodium-ion roj teeb nyob rau hauv UN "Kev Pom Zoo rau Kev Thauj Khoom Zoo" (TDG) Rev. 23: UN 3551 thiab UN 3522.
T.1: Altitude simulation (cell thiab roj teeb)
Test hlwb thiab roj teeb yuav tsum tau muab cia rau ntawm ib tug siab ntawm 11.6 kPa los yog tsawg dua rau tsawg kawg yog rau teev ntawm ambient kub (20 ± 5 ℃) Test hlwb thiab roj teeb yuav tsum tau muab cia rau tsawg kawg yog rau teev ntawm ib tug ntsuas kub sib npaug zos rau 72 ℃ thiab -40 ℃.Cov txheej txheem no yuav tsum tau rov ua dua kom txog thaum 10 tag nrho cov voj voog ua tiav.
Cells thiab roj teeb tau ruaj khov rau lub platform ntawm lub tshuab vibration, nrog rau kev vibration los ua sinusoidal waveform nrog logarithmic cheb ntawm 7 Hz thiab 200 Hz, thiab lub amplitude ntawm 0.8 hli, rau lub xov tooj ntawm tes thiab cov roj teeb me me lub siab tshaj plaws acceleration ntawm 8 gn, thiab rau cov roj teeb loj ntim qhov siab tshaj plaws ntawm 2 gn.Small cell: siab tshaj plaws acceleration ntawm 150 gn, mem tes ntev ntawm 6 milliseconds.Large cell: siab tshaj plaws acceleration ntawm 50 gn, mem tes ntev ntawm 11 milliseconds.
