▍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

| Inzuzo | Iziko lasekhaya laseMelika elinokwamkelwa okuhle e-US naseCanada | Iziko lamazwe ngamazwe linegunya kwaye libonelela ngexabiso elifanelekileyo, likwavunywa nguMntla Melika | Iziko laseMelika elinokwamkelwa kakuhle eMntla Melika |
| Ukusilela |
| Ukunakana kwebhrendi okuncinci kune-UL | Ukuqondwa okungaphantsi kunoko kwe-UL kwisiqinisekiso secandelo lemveliso |
▍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.
I-United States isanda kupapasha izigqibo ezibini zokugqibela kwiRejista ye-Federal
Umhla wokuqalisa: ukusebenza ukususela nge-23 ka-Okthobha 2023. Ithathela ingqalelo ukufumaneka kovavanyo, iKomishoni iya kunikezela ngeentsuku ezili-180 zokunyanzeliswa kwenguqu ukusuka kumhla wama-21 kuSeptemba 2023 ukuya kumhla we-19 kuMatshi, ngo-2024.
Umgaqo wokugqibela: bandakanya i-UL 4200A-2023 kwimimiselo yomanyano njengomthetho osisinyanzelo wokhuseleko lwemveliso yabathengi kwiimveliso zabathengi eziqulethe iiseli zemali okanye iibhetri zemali.
Umhla osebenzayo: iqala ukusebenza ukusuka nge-21 kaSeptemba 2024.
Umgaqo wokugqibela: iimfuno zokuleyibheli zeqhosha leseli okanye upakisho lwebhetri lwenkozo kufuneka luhlangabezane neemfuno ze-16 CFR iSigaba 1263. Ekubeni i-UL 4200A-2023 ingabandakanyi ukufakwa kweelebhile kokupakishwa kwebhetri, ukuleyibhile kuyafuneka kwiqhosha leseli okanye kwi-coin yemali yokupakisha ibhetri.
Umthombo wezigqibo zombini kungenxa yokuba iKhomishoni yoKhuseleko lweMveliso yoMthengi wase-US (CPSC) ivume umgangatho ofunekayo kwivoti yakutshanje-ANSI / UL 4200A-2023, imithetho efunekayo yokhuseleko kwiimveliso zabathengi eziqukethe iiseli zeqhosha okanye iibhetri zeqhosha.
Ngaphambili ngoFebruwari 2023, ngokuhambelana neemfuno "zoMthetho kaReese" owabhengezwa ngo-Agasti 16, 2022, i-CPSC ikhuphe iSaziso sokuPhathwa kweMithetho eCetywayo (NPR) ukulawula ukhuseleko lweemveliso zabathengi eziqulethe iiseli zeqhosha okanye iibhetri zamaqhosha (esibhekisa kwi. I-MCM ye-34th Journal).
