Umgangatho oguquguqukayo ekhaya naphesheya,
UL 1973,

▍Yintoni i-cTUVus & ne-ETL CERTIFICATION?

I-OSHA (i-Occupational Safety and Health Administration), enxulumene ne-US DOL (iSebe lezeMisebenzi), inyanzelisa ukuba zonke iimveliso eziza kusetyenziswa kwindawo yokusebenza kufuneka zivavanywe kwaye ziqinisekiswe yi-NRTL ngaphambi kokuba zithengiswe emarikeni. Imigangatho yovavanyo esebenzayo ibandakanya imigangatho ye-American National Standards Institute (ANSI); Imigangatho ye-American Society for Testing Material (ASTM), imigangatho yeLabhoratri ye-Underwriter (UL), kunye nemigangatho yombutho wokuqaphela okufanayo.

▍OSHA, NRTL, cTUVus, ETL kunye ne-UL inkcazo yamagama kunye nobudlelwane

OSHA:Ushunqulelo loKhuseleko eMsebenzini kunye noLawulo lwezeMpilo. Lumanyano lwe-US DOL (iSebe lezaBasebenzi).

NRTL:Ushunqulelo lweLebhu yoVavanyo eyaMkelwe kuZwelonke. Ijongene noqinisekiso lwaselebhu. Ukuza kuthi ga ngoku, kukho i-18 amaziko ovavanyo lomntu wesithathu avunywe yi-NRTL, kubandakanya iTUV, ITS, MET njalo njalo.

cTUVus:Uphawu lwesatifikethi se-TUVRh eMntla Melika.

ETL:Ufinyezo lweLebhu yoVavanyo loMbane yaseMelika. Yasekwa ngo-1896 nguAlbert Einstein, umqambi waseMelika.

UL:Ushunqulelo lweUnderwriter Laboratories Inc.

▍Umahluko phakathi kwecTUVus, ETL & UL

▍Kutheni i-MCM?

● Inkxaso ethambileyo evela kwisiqinisekiso neteknoloji:Njengelebhu yovavanyo lwamangqina ye-TUVRH kunye ne-ITS kwiSiqinisekiso soMntla waseMelika, i-MCM iyakwazi ukwenza zonke iintlobo zovavanyo kunye nokubonelela ngenkonzo engcono ngokutshintshiselana ngetekhnoloji ubuso ngobuso.

● Inkxaso enzima evela kubuchwepheshe:I-MCM ixhotyiswe ngazo zonke izixhobo zovavanyo lweebhetri ezinkulu, ezinobungakanani obuncinci kunye neeprojekthi ezichanekileyo (oko kukuthi imoto yombane ephathwayo, amandla okugcina, kunye neemveliso zedijithali), ekwazi ukubonelela ngovavanyo lwebhetri ngokubanzi kunye neenkonzo zesatifikethi kuMntla Melika, ukugubungela imigangatho. UL2580, UL1973, UL2271, UL1642, UL2054 njalo njalo.

Kule nyanga, i-UL ihlonyelweUL 1973ngokongeza iimfuno zebhetri yenickel-zinc kunye nokuhlaziya amaxabiso athile ovavanyo lweebhetri zenickel-cadmium kunye neenkqubo zebhetri. Isizathu sikukuba iSihlomelo H asizibandakanyi zonke iikhemikhali zenickel ezinokutshajwa. Isihlomelo H, ekuqaleni ezizezinye iiNdlela zokuVavanya iValve-controlled okanye iVented lead-acid okanye iNickel-cadmium Battery, ngoku ziiNdlela ezizezinye zokuVavanya iValve-controlled or Vented lead- acid okanye Nickel-zinc Iibhetri. Iimeko zovavanyo ezifanelekileyo kwibhetri ye-nickel-zinc zongezwa kwiindlela zokuvavanya ukugqithiswa, i-short-circuit, i-overdischarge, iqondo lokushisa kunye nokumelana nombane.
Ngokutsho kwe-Ofisi Jikelele ye-State Council uluvo malunga nzulu uhlaziyo lwenkqubo yolawulo lombane kunye ne-elektroniki: iibhetri ze-lithium-ion kunye neepakethi zebhetri ezisetyenziswa kwiimveliso zombane kunye ne-elektroniki, iibhanki zamandla, kunye ne-adapter yamandla / itshaja ehambelana neemveliso zokugqibela zonxibelelwano, iya kufakwa kwisiqinisekiso semveliso esisisinyanzelo. Apha ngezantsi kukho iindaba ezimalunga nesatifikethi kunye nemigangatho yovavanyo ebandakanyekayo: I-GB/T 35590-2017 iNgcaciso ngokuBanzi ye-Portable Power Supply for IT Portable Digital Equipment iye yahlaziywa. Inkomfa yengxoxo yemigangatho iya kubanjwa ngo-Oct 13, 2022.Ingcaciso eyongezelelekileyo isaza kufunyanwa malunga nokuba ngowuphi umgangatho omawumkelwe njengomgangatho woqinisekiso novavanyo lweebhetri zelithium kwiimveliso zezixhobo zombane. Okwangoku, umgangatho ofanelekileyo kwiibhetri ze-lithium kwizixhobo ze-SJ / T 11757-2020.
