▍ Gabatarwa na BSMI Gabatarwa na takaddun shaida na BSMI
BSMI gajere ne don Ofishin Ma'auni, Tsarin Mulki da Inspection, wanda aka kafa a cikin 1930 kuma ana kiranta National Metrology Bureau a wancan lokacin. Ita ce babbar ƙungiyar dubawa a Jamhuriyar Sin da ke kula da aikin a kan ma'auni na ƙasa, awoyi da duba samfurori da dai sauransu. BSMI ne ya zartar da ka'idojin bincike na kayan lantarki a Taiwan. An ba da izini samfuran yin amfani da alamar BSMI akan sharuɗɗan da suka dace da buƙatun aminci, gwajin EMC da sauran gwaje-gwaje masu alaƙa.
Ana gwada na'urorin lantarki da samfuran lantarki bisa ga tsare-tsare guda uku masu zuwa: nau'in yarda da nau'in (T), rijistar takaddun samfur (R) da kuma ayyana daidaito (D).
▍ Menene ma'aunin BSMI?
A ranar 20 ga Nuwamba, 2013, BSMI ta sanar cewa daga 1st, Mayu 2014, 3C na biyu na lithium cell / baturi, bankin wutar lantarki na biyu da caja baturin 3C ba a ba su izinin shiga kasuwar Taiwan ba har sai an duba su kuma sun cancanta bisa ga ka'idojin da suka dace (kamar yadda aka nuna a cikin tebur da ke ƙasa).
