▍ Chii chinonzi CB Certification?

IECEE CB ndiyo yekutanga yechokwadi yepasirese sisitimu yekuzivikanwa pamwe chete kwemagetsi emagetsi ekuchengetedza bvunzo mishumo. NCB (National Certification Body) inosvika pachibvumirano chenyika dzakawanda, icho chinoita kuti vagadziri vawane chitupa chenyika kubva kune dzimwe nyika nhengo pasi pechirongwa cheCB nechikonzero chekuendesa chimwe chezvitupa zveNCB.

Chitupa cheCB igwaro repamutemo reCB scheme rakapihwa neNCB ine mvumo, inova yekuzivisa imwe NCB kuti masampula echigadzirwa akaedzwa anowirirana nezvinodiwa zvakajairwa.

Serudzi rwemushumo wakamisikidzwa, mushumo weCB unonyora zvakakodzera zvinodiwa kubva kuIEC yakajairika chinhu nechinhu. Chirevo cheCB hachingopi mhedzisiro yezvese zvinodiwa kuyedzwa, kuyerwa, kuonesa, kuongorora uye kuongorora nekujeka uye kusanzwisisika, asi zvakare kusanganisira mafoto, dhizaini redunhu, mapikicha uye tsananguro yechigadzirwa. Zvinoenderana nemutemo weCB scheme, chirevo cheCB hachizoshanda kudzamara chaunza chitupa cheCB pamwechete.

▍ Nei tichida CB Certification?

1. Directlyrecognized or approvedbynhengonyika

Iine CB chitupa uye CB test report, zvigadzirwa zvako zvinogona kutumirwa kune dzimwe nyika zvakananga.

1. Shandura kune dzimwe nyika zvitupa

Chitupa cheCB chinogona kushandurwa zvakananga kuchitupa chenyika dzenhengo dzayo, nekupa chitupa cheCB, mushumo webvunzo uye mutsauko webvunzo mushumo (kana uchishanda) pasina kudzokorora bvunzo, izvo zvinogona kupfupisa nguva yekutungamira yechitupa.

1. Ita shuwa Kuchengetedzeka kweChigadzirwa

Iyo CB certification bvunzo inotarisa kushandiswa zvine musoro kwechigadzirwa uye chengetedzo inofanoona kana ikashandiswa zvisizvo. Chigadzirwa chakasimbiswa chinoratidza kugutsikana kwezvinodiwa zvekuchengetedza.

▍ Neiko MCM?

● Zvikwaniriso:MCM ndiyo yekutanga kupihwa mvumo CBTL yeIEC 62133 yakajairwa kufanirwa neTUV RH mudunhu reChina.

● Chitupa uye kugona kuyedza:MCM iri pakati pekutanga kuyedza uye certification yechitatu bato yeIEC62133 yakajairwa, uye yapedza zvinopfuura zviuru zvinomwe zvebhatiri IEC62133 kuyedza uye CB mishumo yevatengi vepasirese.

● Rutsigiro rwehunyanzvi:MCM ine anopfuura gumi neshanu mainjiniya ane hunyanzvi mukuyedza sepaIEC 62133 standard. MCM inopa vatengi ruzivo rwakakwana, rwakakwana, rwakavharika-loop yerutsigiro rwehunyanzvi uye inotungamira-kumucheto ruzivo masevhisi.

Iyo Cellular Telecommunications Industry Association (CTIA) ine certification scheme inovhara maseru, mabhatiri, adapta uye mahosti uye zvimwe zvigadzirwa zvinoshandiswa mumagetsi ekukurukurirana zvigadzirwa (senge mbozhanhare, malaptop). Pakati pavo, CTIA certification yemasero inonyanya kuomarara. Kunze kwekuyedzwa kwekuita kwekuchengetedza kwakawanda, CTIA inotarisawo pane dhizaini yemaseru, iwo akakosha maitiro ekugadzira uye kutonga kwayo kwemhando. Kunyangwe chitupa cheCTIA chisiri chekusungirwa, vakuru venharembozha muNorth America vanoda kuti zvigadzirwa zvevanopa vatengesi vavo vapfuure chitupa cheCTIA, saka chitupa cheCTIA chinogonawo kutorwa sechinhu chinodiwa chekupinda pamusika wekuNorth America wekutaurirana. uye IEEE 1625 yakabudiswa neIEEE (Institute of Electrical and Electronics Engineers). Kare, IEEE 1725 yaishandiswa kumabhatiri asina nhevedzano chimiro; nepo IEEE 1625 ichishandiswa kumabhatiri ane maviri kana anopfuura akatevedzana ekubatanidza. Sezvo chirongwa cheCTIA bhatiri chitupa chave chichishandisa IEEE 1725 seyereferensi, mushure mekuburitswa kweshanduro itsva yeIEEE 1725-2021 muna 2021, CTIA yakaumbawo boka rinoshanda kuti ritange chirongwa chekuvandudza CTIA certification scheme. vakakumbira pfungwa kubva kumarabhoritari, vagadziri vemabhatiri, vagadziri venharembozha, vanogadzira madhiraivha, nezvimwewo. Muna Chivabvu wegore rino, musangano wekutanga weCRD (Certification Requirements Document) wakaitwa. Munguva iyi, boka rakasarudzika rakagadzirwa kuti rikurukure USB interface uye dzimwe nyaya zvakasiyana. Pashure peinopfuura hafu yegore, musangano wokupedzisira wakaitwa mwedzi uno. Inosimbisa kuti chirongwa chitsva chetifiketi cheCTIA IEEE 1725 (CRD) chichapihwa muna Zvita, paine nguva yekuchinja yemwedzi mitanhatu. Izvi zvinoreva kuti certification yeCTIA inofanira kuitwa pachishandiswa vhezheni itsva yegwaro reCRD mushure meChikumi 2023. Isu, MCM, senhengo yeCTIA's Test Laboratory (CATL), uye CTIA's Battery Working Group, takaronga kudzokorora chirongwa chitsva chebvunzo uye takatora chikamu. mukati meCTIA IEEE1725-2021 CRD hurukuro. Aya anotevera ndiwo akakosha kudzokorora: Zvinodiwa zvebhatiri / pack subsystem yakawedzerwa, zvigadzirwa zvinoda kusangana ne UL 2054 kana UL 62133-2 kana IEC 62133-2 (ine US kutsauka). Zvakakosha kucherechedza kuti kare hapana chikonzero chekupa chero magwaro epakiti.
