Kev txhais lus nthuav dav ntawm IEC 62133: 2017+AMD1: 2021 (edition 1.1),
CB,

▍ Dab tsi yogCBDaim ntawv pov thawj?

IECEECByog 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.

【Summary of Standard Revision】
Cov qauv no yog ib qho kev sib xyaw ua ke ntawm IEC 62133: 2017 thiab AMD1: 2021, feem ntau suav nrog plaub qhov kev kho dua tshiab (saib hauv qab cov ntsiab lus kho dua tshiab). Nws yog ntau txog qhov ua tiav ntawm tus qauv qub, tsis muaj kev hloov kho ntau dhau, yog li ntawd, tsis muaj peev xwm kuaj tau. Tab sis kev hloov pauv hauv qee cov lus xeem yuav cuam tshuam rau qhov kev xeem.
【Cov ntsiab lus kho dua tshiab】
1, 7.1.2: Kev kho dua ntawm cov txheej txheem them nyiaj: tsis siv qhov kev hloov kho ntawm kev txiav tawm tam sim no
ntawm flash charge batteries, tab sis tsuas yog qee cov ntawv kho thiab ntxiv.
7.1.2 Cov txheej txheem thib ob
Txoj kev them nyiaj no tsuas yog siv rau 7.3.1, 7.3.4, 7.3.5, thiab 7.3.9.
Tom qab stabilization rau 1 h-thiab 4 h, ntsig txog, ntawm qhov ntsuas kub ntawm qhov ntsuas kub siab tshaj plaws thiab qhov ntsuas kub qis tshaj plaws, feem, raws li tau teev tseg hauv Table 2, cov hlwb raug them los ntawm kev siv lub siab tshaj plaws them nqi hluav taws xob thiab qhov siab tshaj plaws them tam sim no , kom txog rau thaum tus nqi them tam sim no raug txo mus rau 0,05 Nws A, siv qhov tam sim no tas li mus rau qhov ntsuas hluav taws xob tas li.
IEC 62133-2: 2017 + AMD1: 2021 CSV - 15- IEC 2021
CEEB TOOM Qhov voltage thiab tam sim no tuaj yeem sib txawv nyob ntawm qhov kub thiab txias (xws li yog tween T2 thiab T3 los yog nruab nrab ntawm T1 thiab T4 ntawm daim duab A.1).Stabilization lub sij hawm nyob rau hauv lub sij hawm teev yuav tsum tso cai rau thermal equilibrium mus txog qhov twg ua tau
