▍BSMI Isingeniso Isingeniso se-BSMI
I-BSMI imfushane nge-Bureau of Standards, Metrology and Inspection, eyasungulwa ngo-1930 futhi yabizwa ngeNational Metrology Bureau ngaleso sikhathi. Kuyinhlangano ephakeme yokuhlola eRiphabhulikhi yaseShayina ephethe umsebenzi kumazinga kazwelonke, i-metrology nokuhlolwa komkhiqizo njll. Amazinga okuhlolwa kwezinto zikagesi e-Taiwan agunyazwa yi-BSMI. Imikhiqizo igunyaziwe ukusebenzisa ukumaka kwe-BSMI ezimeni lapho ithobelana nezidingo zokuphepha, ukuhlolwa kwe-EMC nokunye ukuhlola okuhlobene.
Izinto zikagesi kanye nemikhiqizo ye-elekthronikhi ihlolwa ngokwalezi zinhlelo ezintathu ezilandelayo: uhlobo olugunyazwe (T), ukubhaliswa kwesitifiketi somkhiqizo (R) kanye nesimemezelo sokuvumelana (D).
▍Liyini izinga le-BSMI?
Ngomhla zingama-20 kuNovemba 2013, kumenyezelwe yi-BSMI ukuthi kusuka ku-1st, Meyi 2014, iseli/ibhethri le-3C lesibili le-lithium, ibhange lamandla e-lithium yesibili kanye neshaja yebhethri engu-3C azivunyelwe ukufinyelela emakethe yase-Taiwan zize zihlolwe futhi zifaneleke ngokuya ngamazinga afanele (njengoba kuboniswe kuthebula elingezansi).
| Isigaba somkhiqizo sokuhlola | Ibhethri le-3C Lesibili Lithium elineseli eyodwa noma iphakethe (umumo wenkinobho awufakiwe) | I-3C Secondary Lithium Power Bank | Ishaja yebhethri ye-3C |
Amazwana: Inguqulo ye-CNS 15364 1999 isebenza kuze kube umhla zingama-30 kuMbasa 2014. Iseli, ibhethri kanye Iselula yenza ukuhlolwa komthamo kuphela nge-CNS14857-2 (inguqulo ka-2002).

▍Kungani i-MCM?
● Ngo-2014, ibhethri ye-lithium ekwazi ukushajwa kabusha yaba isibopho e-Taiwan, futhi i-MCM yaqala ukunikeza ulwazi lwakamuva mayelana nesitifiketi se-BSMI kanye nesevisi yokuhlola kumakhasimende omhlaba, ikakhulukazi lawo avela ezweni lase-China.
● Izinga eliphezulu lokudlula:I-MCM isivele isisize amakhasimende ukuthi athole izitifiketi ze-BSMI ezingaphezu kuka-1,000 kuze kube manje ngesikhathi esisodwa.
● Amasevisi ahlanganisiwe:I-MCM isiza amakhasimende ukuthi angene ngempumelelo ezimakethe eziningi emhlabeni jikelele ngokusebenzisa isevisi yenqwaba yesitophu esisodwa yenqubo elula.
Nakuba kuwukuzithandela ngokwemvelo, idokhumenti esemthethweni iphinde yasho ukuthi uma kukhona amayunithi achaza lesi sitifiketi “njengesisekelo semibandela yaso eyisibopho, thobelana nezinhlinzeko zaso. Ihlukile kumodi yohlelo lwebhethri ye-CCC, amasistimu ebhethri nawo adinga ukuhlolwa kwasembonini bese ekhipha umbiko. Ukuhlolwa kwasefekthri kuyadingeka okokuqala ngqa ukuze ufake isicelo sokuthola isitifiketi, kuyilapho ukungezwa okulandelayo kumamodeli ochungechunge akudingi ukuphinda ukuhlolwa kwasembonini. Nokho, ukuhlolwa kwefekthri kwaminyaka yonke kuyadingeka ukuze kugcinwe isitifiketi, kuyilapho amaseli ebhethri engadingeki.
Inguqulo entsha ikhuluma ngokuhlolwa okusha okuphoqiwe kokushoda kwangaphakathi. Indlela entsha iwukugqugquzela ukushoda kwangaphakathi ngokungena ukuze udale amathebhu amahle noma angalungile kusinqamuleli sesendlalelo 1 no-2. Inqubo ilandelwa kanje: 1. Ukulungiswa kweseli: Gcoba imbobo phakathi nendawo yobuso obukhulu kunabo bonke (njengezibalo ezingezansi) noma ubeke imbobo lapho kukhiqizwa ukuze kungene umoya.2. Ukulungiswa kweseli: Ngemva kokushajwa ngokugcwele, lungisa iseli kumathuluzi okuhlola. Iseli lizohlukaniswa ngogesi ebhentshini lokuhlola. Iseli kanye ne-indenter izohamba eduze kwe-eksisi ye-perpendicular. Indawo yokuhlehlisa izofana naleyo echazwe kusishosha esiphoqelelwe sangaphakathi.
