▍BSMI Intshayelelo yesiqinisekiso seBSMI
I-BSMI imfutshane kwiBureau yeMigangatho, iMetrology kunye noHlolo, eyasekwa ngo-1930 kwaye yabizwa ngokuba yiNational Metrology Bureau ngelo xesha. Ingumbutho wokuhlola ophezulu kwiRiphabhlikhi yaseChina ophethe umsebenzi kwimigangatho yesizwe, i-metrology kunye nokuhlolwa kwemveliso njl.njl. Imigangatho yokuhlola izixhobo zombane eTaiwan yenziwe yi-BSMI. Iimveliso zigunyaziswe ukuba zisebenzise uphawu lwe-BSMI phantsi kweemeko ezihambelana neemfuno zokhuseleko, uvavanyo lwe-EMC kunye nezinye iimvavanyo ezinxulumene nazo.
Izixhobo zombane kunye neemveliso zombane zivavanywa ngokwezi zicwangciso zintathu zilandelayo: uhlobo oluvunyiweyo (T), ukubhaliswa kwesiqinisekiso semveliso (R) kunye nokubhengezwa kokuthotyelwa (D).
▍Uthini umgangatho weBSMI?
Nge-20 kaNovemba ka-2013, ibhengezwe yi-BSMI ukuba ukusuka kwi-1st, NgoMeyi 2014, i-3C yesibini ye-lithium cell / ibhetri, ibhanki yamandla e-lithium yesibini kunye ne-3C ishaja yebhetri ayivumelekanga ukufikelela kwimarike yaseTaiwan de ihlolwe kwaye ifaneleke ngokwemigangatho efanelekileyo (njengoko kuboniswe kwitheyibhile engezantsi).
| Udidi lweMveliso yoVavanyo | Ibhetri ye-3C yeSekondari yeLithium eneseli enye okanye ipakethe (imilo yeqhosha ayibandakanywanga) | IBhanki yaMandla yeLithium yesibini ye-3C | Itshaja yebhetri ye-3C |
Amagqabantshintshi: Inguqulelo ye-CNS 15364 1999 iyasebenza ukuya kuma-30 kuTshazimpuzi 2014. Iseli, ibhetri kunye Iselfowuni yenza uvavanyo lwamandla kuphela nge-CNS14857-2 (uguqulelo luka-2002).

▍Kutheni i-MCM?
● Kwi-2014, ibhetri ye-lithium ehlaziywayo yaba yimfuneko eTaiwan, kwaye i-MCM yaqala ukubonelela ngolwazi lwamva nje malunga nesatifikethi se-BSMI kunye nenkonzo yokuvavanya kubaxhasi behlabathi, ngakumbi abo bavela kwilizwe laseChina.
● Umgangatho wokuPasa oPhezulu:I-MCM sele incede abathengi ukuba bafumane ngaphezu kwe-1,000 lezatifikethi ze-BSMI kude kube ngoku ngexesha elinye.
● Iinkonzo ezihlanganisiweyo:I-MCM inceda abathengi ukuba bangene ngempumelelo kwiimarike ezininzi kwihlabathi liphela ngenkonzo edityanisiweyo yenkqubo elula.
IKomishoni yoKhuseleko lweMveliso yoMthengi (CPSC) ibhengeze ngoJanuwari 11 ukuba icela urhulumente wesigqeba ukuba atyumbe ibhilikhwe yokuseka umgangatho wokhuseleko lweebhetri zengqekembe, iiseli zeqhosha kunye neemveliso zabathengi ezenziwe ngeebhetri zengqekembe kunye neeseli zeqhosha. Esi saziso sifunwa nguMthetho kaReese, owamiselwa nge-16 ka-Agasti ka-2022 kwaye watyikitywa nguMongameli wase-US uJoe Biden ekhumbula umntwana oyintombazana oneenyanga ezili-18 ubudala, uReese Hammersmith, owasweleka ngenxa yokuginya ngempazamo ibhetri yemali. . Ngoko ke, ukwenzela ukukhusela abantwana abaneminyaka emithandathu ubudala okanye abancinci ekuginyweni ngengozi kweebhetri zeqhosha ezibangela umonakalo emzimbeni, isicelo senziwe ukuba kuphuhliswe imigangatho efanelekileyo kunye nemimiselo. ezinkulu ububanzi kunobude bazo kwaye zimiselwe yi-CPSC ukuba zenze ukwenzakala xa ziginyiwe. Umthetho oyilwayo awucingi umgaqo kunye nokwakhiwa kweekhemikhali zebhetri, kodwa kuphela imilo. Kwaye iibhetri ezinobubanzi obungaphantsi kobude bebhetri, njenge-AAA uhlobo lweebhetri zecylindrical, umthetho kaReese awuqwalaselwa okwangoku. Iimveliso zabathengi eziphantsi komthetho kaReese ziquka iimveliso ezineebhetri zengqekembe kunye neemveliso zabathengi ezenzelwe ukusebenzisa iibhetri zemali, nokuba. iibhetri ziqulethwe emzimbeni ngexesha lokuthengisa. Nangona kunjalo, iimveliso zokudlala ezithobela i-ASTM F963 US yeMimiselo yeToy yaBantwana azixolelwanga.
