▍Kodi CB Certification ndi chiyani?

IECEE CB ndiye njira yoyamba yapadziko lonse lapansi yovomerezera malipoti oyesa chitetezo cha zida zamagetsi. NCB (National Certification Body) ifika pa mgwirizano wamayiko osiyanasiyana, womwe umathandizira opanga kuti apeze ziphaso zadziko kuchokera kumayiko ena omwe ali mamembala pansi pa dongosolo la CB potengera kusamutsa chimodzi mwa ziphaso za NCB.

Satifiketi ya CB ndi chikalata chovomerezeka cha CB choperekedwa ndi NCB yovomerezeka, chomwe ndikudziwitsa NCB ina kuti zitsanzo zazinthu zoyesedwa zikugwirizana ndi zomwe zikufunika.

Monga mtundu wa lipoti lokhazikika, lipoti la CB limatchula zofunikira kuchokera ku IEC wamba ndi chinthu. Lipoti la CB silimangopereka zotsatira za mayeso onse ofunikira, kuyeza, kutsimikizira, kuyang'anira ndi kuwunika momveka bwino komanso mosadziwika bwino, komanso kuphatikiza zithunzi, chithunzi chozungulira, zithunzi ndi malongosoledwe azinthu. Malinga ndi lamulo la CB scheme, lipoti la CB siligwira ntchito mpaka litapereka satifiketi ya CB palimodzi.

▍Nchifukwa chiyani timafunikira CB Certification?

1. Chindunjilykuzindikirazedi or kuvomerezaedmwamembalamayiko

Ndi satifiketi ya CB ndi lipoti la mayeso a CB, malonda anu amatha kutumizidwa kumayiko ena mwachindunji.

1. Sinthani kumayiko ena ziphaso

Satifiketi ya CB imatha kusinthidwa mwachindunji kukhala satifiketi ya mayiko omwe ali mamembala ake, popereka satifiketi ya CB, lipoti la mayeso ndi lipoti loyesa kusiyana (ngati kuli kotheka) osabwereza mayeso, omwe angafupikitse nthawi yotsogolera yotsimikizira.

1. Onetsetsani Chitetezo cha Zamalonda

Mayeso a certification a CB amawona kugwiritsidwa ntchito moyenera kwa chinthucho komanso chitetezo chodziwikiratu chikagwiritsidwa ntchito molakwika. Chitsimikizo chotsimikizika chimatsimikizira zokhutiritsa zofunikira zachitetezo.

▍Chifukwa chiyani MCM?

● Ziyeneretso:MCM ndiye CBTL yoyamba yovomerezeka ya IEC 62133 yovomerezeka ndi TUV RH ku China.

● Chitsimikizo ndi kuthekera koyesa:MCM ili m'gulu loyamba loyesa ndi kutsimikizira chipani chachitatu pa muyezo wa IEC62133, ndipo yamaliza kuyesa kwa batri 7000 IEC62133 ndi malipoti a CB kwa makasitomala apadziko lonse lapansi.

● Thandizo laukadaulo:MCM ili ndi mainjiniya opitilira 15 odziwika bwino pakuyesa malinga ndi muyezo wa IEC 62133. MCM imapatsa makasitomala chithandizo chokwanira, cholondola, chotsekeka komanso chithandizo chaukadaulo chotsogola.

Cellular Telecommunications Industry Association (CTIA) ili ndi dongosolo la certification lophimba ma cell, mabatire, ma adapter ndi makamu ndi zinthu zina zomwe zimagwiritsidwa ntchito pazinthu zoyankhulirana zopanda zingwe (monga mafoni am'manja, ma laputopu). Pakati pawo, certification ya CTIA yama cell ndiyovuta kwambiri. Kupatula kuyesedwa kwachitetezo chambiri, CTIA imayang'ananso mapangidwe a maselo, njira zazikulu zopangira komanso kuwongolera kwake. Ngakhale satifiketi ya CTIA sikofunikira, oyendetsa ma telecom ku North America amafuna kuti zinthu zomwe ogulitsa awo azipereka ziphatikizepo satifiketi ya CTIA, chifukwa chake satifiketi ya CTIA imatha kuonedwanso ngati chofunikira kuti mulowe msika wolumikizirana waku North America. Mulingo wa certification wa CTIA nthawi zonse umatchula IEEE 1725 ndi IEEE 1625 lofalitsidwa ndi IEEE (Institute of Electrical and Electronics Engineers). M'mbuyomu, IEEE 1725 idagwiritsidwa ntchito ku mabatire opanda dongosolo; pomwe IEEE 1625 imagwiritsidwa ntchito pamabatire okhala ndi zolumikizira ziwiri kapena zingapo. Monga pulogalamu ya satifiketi ya batri ya CTIA yakhala ikugwiritsa ntchito IEEE 1725 ngati muyezo, pambuyo pa kutulutsidwa kwa mtundu watsopano wa IEEE 1725-2021 mu 2021, CTIA yapanganso gulu lothandizira kuyambitsa pulogalamu yokonzanso certification scheme ya CTIA. Gulu logwira ntchito mozama anapempha maganizo kuchokera ku ma laboratories, opanga mabatire, opanga mafoni a m'manja, opanga makamu, opanga ma adapter, ndi zina zotero. Mu May chaka chino, msonkhano woyamba wa CRD (Certification Requirements Document) unachitika. Panthawiyi, gulu lapadera la adaputala linakhazikitsidwa kuti likambirane za mawonekedwe a USB ndi nkhani zina mosiyana. Patadutsa theka la chaka, semina yomaliza idachitika mwezi uno. Zimatsimikizira kuti dongosolo latsopano la certification la CTIA IEEE 1725 (CRD) lidzaperekedwa mu December, ndi kusintha kwa miyezi isanu ndi umodzi. Izi zikutanthauza kuti certification ya CTIA iyenera kuchitidwa pogwiritsa ntchito mtundu watsopano wa chikalata cha CRD pambuyo pa Juni 2023. Ife, MCM, monga membala wa CTIA's Test Laboratory (CATL), ndi CTIA's Battery Working Group, tinakonza zokonzanso dongosolo latsopanoli ndipo tinatenga nawo mbali. pazokambirana za CTIA IEEE1725-2021 CRD. Zotsatirazi ndi zofunika kukonzanso: Zofunikira pa batire / paketi subsystem zidawonjezedwa, zogulitsa ziyenera kukumana ndi UL 2054 kapena UL 62133-2 kapena IEC 62133-2 (yopatuka ku US). Ndikoyenera kudziwa kuti m'mbuyomu palibe chifukwa choperekera zikalata zilizonse za paketi.
