▍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) | I-3C yeSekondari yeBhanki yaMandla yeLithium | 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.
Ngomhla wama-20 kaDisemba, iKomiti yoKhuseleko lweMveliso yoMthengi waseMelika (CPSC) yathumela inqaku kwiwebhusayithi yayo ibiza abavelisi bee-scooters zombane, i-balance scooters, iibhayisekile zombane kunye nee-unicycles zombane ukuba baphicothe iimveliso zabo ukuqinisekisa ukuba bayahlangabezana nemigangatho yokhuseleko esekelwe ngokuzithandela, okanye banokuthi. inyathelo lokunyanzeliswa kobuso.I-CPSC yathumela iileta zengxelo kubavelisi nabarhwebi ngaphandle kwe-2,000 echaza ukuba ukusilela ukuthobela imigangatho yokhuseleko ye-UL esebenzayo (ANSI/CAN/UL 2272 – Umgangatho weNkqubo yoMbane yeSithuthi soMbane, kunye ne-ANSI/CAN/UL 2849 – Umgangatho weBhayisekile yoMbane yeeNkqubo zoKhuseleko zoMbane, kunye nemigangatho yazo ekhankanyiweyo) inokubeka umngcipheko womlilo, ukwenzakala kakhulu okanye ukufa kubathengi; kunye nokuba ukuthotyelwa kwemveliso kunye nemigangatho ye-UL efanelekileyo kunokunciphisa kakhulu ingozi yokwenzakala okanye ukufa okubangelwa ngumlilo kwizixhobo zokuhamba ezincinci.Ukususela ngoJanuwari 1, 2021 ukuya kuNovemba 28, 2022, i-CPSC ifumene iingxelo ubuncinane ezingama-208 zokutsha kweminivan okanye izehlo ezishushu kakhulu. ukusuka kumazwe angama-39, okubangele ukufa kwabantu abali-19 ubuncinane. Le leta ihlabela mgama icela abavelisi ukuba babonise ukuthobela umgangatho ngokunikwa isiqinisekiso yilabhoratri yovavanyo evunyiweyo.
