▍ 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.
