▍ 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.

● Certification uye kuyedza kugona: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.

Musi waChivabvu 21, 2021, UL yepamutemo webhusaiti yakaburitsa ichangoburwa chirevo cheUL1973 bhatiri chiyero chezvakamira, mota yekubatsira magetsi uye light rail (LER) application. Nguva yekupedzisira yekutaura ndiChikunguru 5, 2021. Izvi zvinotevera zvirevo makumi matatu neshanu:
1. Kuedzwa kweModules panguva yenguva pfupi yedunhu bvunzo.
2. Kugadziriswa kwekunyora.
3. Kuwedzerwa kwekusarudzika kune General Performance Chikamu chenguva yekuyedza ye lithium ion masero.

7. Kufambisa ese e lithium cell zvinodiwa muUL 1973.
8. Kuwedzerwa kwezvinodiwa zvekudzorerazve mabhatiri.
9. Kujekeswa kwe lead acid bhatiri zvinodiwa.
10. Kuwedzerwa kweMotokari Yekubatsira Simba System Zvinodiwa.
