▍ Daim ntawv pov thawj CB yog dab tsi?

IECEE CB yog thawj txoj hauv kev thoob ntiaj teb rau kev sib koom ua ke ntawm cov khoom siv hluav taws xob kev nyab xeeb kev xeem ntawv ceeb toom. NCB (National Certification Body) ncav cuag ntau qhov kev pom zoo, uas ua rau cov tuam txhab tau txais daim ntawv pov thawj hauv tebchaws los ntawm lwm lub teb chaws cov tswv cuab raws li CB cov tswv yim raws li kev hloov pauv ib qho ntawm NCB daim ntawv pov thawj.

CB daim ntawv pov thawj yog ib daim ntawv pov thawj CB raws li daim ntawv tso cai NCB, uas yog qhia rau lwm tus NCB tias cov khoom kuaj kuaj ua raws li cov qauv yuav tsum tau ua.

Raws li hom ntawv tshaj tawm, CB daim ntawv tshaj tawm teev cov kev xav tau los ntawm IEC tus qauv khoom los ntawm cov khoom. CB daim ntawv tshaj tawm tsis yog tsuas yog muab cov txiaj ntsig ntawm txhua qhov kev ntsuas uas xav tau, ntsuas, tshawb xyuas, tshuaj xyuas thiab kev ntsuas nrog qhov tseeb thiab tsis meej, tab sis kuj suav nrog cov duab, daim duab kos duab, duab thiab cov lus piav qhia ntawm cov khoom. Raws li txoj cai ntawm CB scheme, CB daim ntawv tshaj tawm yuav tsis siv mus txog thaum nws nthuav tawm nrog CB daim ntawv pov thawj ua ke.

▍ Vim li cas peb thiaj xav tau CB Certification?

1. Ncaj nraimlylees paubzej or pom zooedlos ntawmtus tswv cuablub teb chaws

Nrog CB daim ntawv pov thawj thiab CB xeem daim ntawv tshaj tawm, koj cov khoom tuaj yeem raug xa tawm mus rau qee lub tebchaws ncaj qha.

1. Hloov mus rau lwm lub tebchaws daim ntawv pov thawj

Daim ntawv pov thawj CB tuaj yeem hloov pauv ncaj qha mus rau daim ntawv pov thawj ntawm nws cov tswvcuab hauv tebchaws, los ntawm kev muab CB daim ntawv pov thawj, daim ntawv pov thawj kev xeem thiab cov ntawv xeem sib txawv (thaum muaj feem xyuam) yam tsis tau rov ua dua qhov kev xeem, uas tuaj yeem txo lub sijhawm ua haujlwm ntawm kev lees paub.

1. Xyuas kom muaj kev nyab xeeb ntawm cov khoom

CB daim ntawv pov thawj kuaj xyuas cov khoom siv tsim nyog thiab pom tau tias muaj kev nyab xeeb thaum siv tsis raug. Cov khoom muaj ntawv pov thawj ua pov thawj qhov txaus siab ntawm qhov yuav tsum tau muaj kev nyab xeeb.

▍ Vim li cas MCM?

● Kev Tsim Nyog:MCM yog thawj daim ntawv tso cai CBTL ntawm IEC 62133 tus qauv tsim nyog los ntawm TUV RH hauv Suav teb av loj.

● Daim ntawv pov thawj thiab kev xeem muaj peev xwm:MCM yog thawj thaj chaw ntawm kev sim thiab ntawv pov thawj thib peb rau IEC62133 tus qauv, thiab tau ua tiav ntau tshaj 7000 roj teeb IEC62133 kev sim thiab CB cov ntaub ntawv rau cov neeg siv khoom thoob ntiaj teb.

● Kev pab txhawb nqa:MCM muaj ntau dua 15 tus kws tshaj lij kws tshaj lij tshwj xeeb hauv kev sim raws li IEC 62133 tus qauv. MCM muab cov neeg siv khoom nrog cov lus qhia dav dav, raug, kaw-voj hom kev txhawb nqa thiab cov kev pabcuam cov ntaub ntawv ua ntej.

Lub hli no, UL tau hloov khoUAS 1973los ntawm kev ntxiv cov nickel-zinc roj teeb uas yuav tsum tau ua thiab kho qee qhov kev ntsuas qhov tseem ceeb rau cov roj teeb nickel-cadmium thiab cov roj teeb. Qhov laj thawj yog tias Daim Ntawv Ntxiv H tsis suav nrog txhua cov tshuaj nickel rechargeable.
"Nickel-zinc roj teeb" ntxiv rau cov lus piav qhia hauv ntu 1.4, 6.46, 7.12.1, 7.12.8, 45.8, 45.9, 45.10. 45.11. -acid lossis Nickel-zinc roj teeb. Cov kev kuaj mob tsim nyog rau nickel-zinc roj teeb yog ntxiv rau cov kev sim ntawm overcharge, luv-circuit, overdischarge, kub thiab voltage kuj.Appendix H hloov qhov txiav tawm voltage ntawm nickel-cadmium hlwb rau 1.0 V.Appendix H kuj ntxiv. compression zog thiab ntsuas kub ntawm qhov system theem.
Raws li Lub Chaw Haujlwm Saib Xyuas Kev Ruaj Ntseg Hauv Lub Xeev txoj kev xav txog kev nkag siab tob txog kev hloov kho hluav taws xob thiab hluav taws xob kev lag luam kev lag luam: cov roj teeb lithium-ion thiab cov roj teeb uas siv hauv cov khoom siv hluav taws xob thiab hluav taws xob, lub tsev txhab nyiaj fais fab, thiab lub hwj chim adapter / charger matched nrog kev sib txuas lus kawg khoom, yuav suav nrog hauv daim ntawv pov thawj cov khoom uas yuav tsum tau ua. Hauv qab no yog qee cov xov xwm hais txog cov ntawv pov thawj & cov qauv ntsuas kev koom tes:
GB / T 35590-2017 Cov Lus Qhia Tshwj Xeeb rau Portable Fais Fab rau IT Portable Digital Equipment tau raug kho dua. Lub rooj sib tham tus qauv kev sib tham yuav muaj nyob rau lub Kaum Hlis 13, 2022.
Qhov hloov kho version ntawm GB 31241 tseem tsis tau tso tawm. Nws yuav tsum raug tso tawm ua ntej 3C daim ntawv pov thawj raug muab coj los siv.Ntau cov ntaub ntawv tseem yuav tau txais raws li tus qauv yuav tsum tau txais raws li daim ntawv pov thawj thiab cov qauv kuaj rau lithium roj teeb rau cov khoom siv hluav taws xob. Tam sim no, tus qauv tsim nyog tshaj plaws rau cov roj teeb lithium rau cov khoom siv yog SJ / T 11757-2020.
MCM yuav tsom mus ntxiv rau qhov kev nce qib muab cov ntaub ntawv tshiab tshaj plaws rau
