Menene CB Certification?

IECEE CB shine tsarin farko na gaskiya na kasa da kasa don fahimtar juna game da rahotannin gwajin amincin kayan lantarki. Hukumar NCB (Hukumar Takaddun Shaida ta Kasa) ta cimma yarjejeniya ta bangarori daban-daban, wanda ke baiwa masana'antun damar samun takardar shedar kasa daga wasu kasashe mambobi a karkashin tsarin CB bisa canja wurin daya daga cikin takaddun NCB.

Takaddun shaida na CB takardar shedar tsarin CB ce ta hukuma wacce NCB mai izini ke bayarwa, wanda shine sanar da sauran NCB cewa samfuran samfuran da aka gwada sun dace da daidaitattun buƙatu.

A matsayin nau'in daidaitaccen rahoto, rahoton CB ya lissafa abubuwan da suka dace daga daidaitaccen abu na IEC da abu. Rahoton CB ba wai kawai yana ba da sakamakon duk gwajin da ake buƙata ba, aunawa, tabbatarwa, dubawa da ƙima tare da tsabta da rashin fahimta, amma har da hotuna, zane-zane, hotuna da bayanin samfur. Dangane da tsarin tsarin CB, rahoton CB ba zai yi tasiri ba har sai ya gabatar da takardar shaidar CB tare.

Me yasa muke buƙatar Takaddun shaida na CB?
