UL 2054,
▍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

| 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.
UL 2054I-Ed.3 ikhutshwe ngoNovemba 17, 2021. Njengelungu lomgangatho we-UL, i-MCM ithathe inxaxheba ekuhloleni umgangatho, kwaye yenza iingcebiso ezifanelekileyo zokuguqulwa okwamkelwa emva koko.
Utshintsho olwenziwayo kwimigangatho lubandakanyeka ikakhulu kwimiba emihlanu, ethi icaciswe ngolu hlobo lulandelayo:Uhlaziyo oluyingxubevange lwenziwa kuwo wonke uMgangatho; Amacandelo 2 - 5, 6.1.2 - 6.1.4,
6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, isihloko seCandelo 23, 24.1, iSihlomelo A. Ukucaciswa kweemfuno zeelebhile zokunamathela; ICandelo lama-29, 30.1, 30.2.Ukongezwa kweemfuno kunye neendlela zoVavanyo loKuhlala ixesha elide .Yenziwe UVavanyo loMthombo waMandla oMnyiniweyo oluyimfuneko yokuzikhethela; 7.1.Icaciswe ukuchasana kwangaphandle kuvavanyo kwi-11.11. Uvavanyo lweSekethe eLufutshane lwamiselwa ukuba lusebenzise ucingo lobhedu kwisekethe emfutshane ene-anode elungileyo nengalunganga kwicandelo 9.11 lomgangatho wokuqala, ngoku luhlaziywe kusetyenziswa i-80±20m.
Ω izixhasi zangaphandle.
Ukongezwa kwecandelo 6.3: Iimfuno ngokubanzi zolwakhiwo lweengcingo kunye neetheminali: Ucingo kufuneka lugqunywe, kwaye kufuneka luhlangabezane neemfuno ze-UL 758 ngelixa uqwalasela ukuba ubushushu obunokwenzeka kunye nombane odibana nawo kwipakethi yebhetri yamkelekile. ziqiniswe ngoomatshini, kwaye kufuneka kuqhagamshelwane nombane, kwaye kungabikho ntlupheko kwimidibaniso kunye neetheminali. Ilothe kufuneka ikhuseleke, kwaye igcinwe kude kwincam ezibukhali kunye nezinye iindawo ezinokuthi zonakalise isigqubuthelo socingo.
