Siyakuhalalisela u-Weeyu ngokuthola isitifiketi se-UL kithiUchungechunge lwe-M3Pezingeni 2 32amp 7kw kanye 40amp 10kw ekhaya EV iziteshi zokushaja.Njengomkhiqizi wokuqala noyedwa othola i-UL ohlwini lwayo yonke ishaja hhayi izingxenye ezivela e-China, isitifiketi sethu sihlanganisa kokubili i-USA ne-Canada.Inombolo yesitifiketi i-E517810 isiqinisekisiwe kuwebhu ye-UL.
Yini i-UL?
I-UL imele i-Underwriter Laboratories, inkampani yesitifiketi senkampani yangaphandle esineminyaka engaphezu kwekhulu ikhona.I-UL yasungulwa ngo-1894 eChicago.Baqinisekisa imikhiqizo ngenhloso yokwenza umhlaba ube indawo ephephile kubo bobabili abasebenzi nabathengi.Ngaphandle kokuhlola, babeka izindinganiso zezimboni okufanele bazilandele lapho besungula imikhiqizo emisha.Ngonyaka odlule kuphela, cishe imikhiqizo eyizigidi eziyizinkulungwane eziyi-14 enophawu lwe-UL yangena emakethe yomhlaba.
Ngamafuphi, i-UL ingu-ainhlangano yezokuphephaebeka amazinga embonini yonkana emikhiqizweni emisha.Bahlala behlola le mikhiqizo ukuze baqinisekise ukuthi ifinyelela kulawa mazinga.Ukuhlolwa kwe-UL kuqinisekisa ukuthi osayizi bezintambo balungile noma amadivayisi angakwazi ukuphatha inani lamanje abathi angakwazi.Baphinde baqinisekise ukuthi imikhiqizo yakhiwe ngendlela efanele ukuze kuphephe kakhulu.
Umbono oyiphutha ojwayelekile ukuthi i-UL ihlola yonke imikhiqizo ngokwayo.Lokhu akuhlali kunjalo.Kunalokho, i-UL igunyaza umkhiqizi ukuthi azihlolele umkhiqizo ngokwakhe esebenzisa isitembu se-UL.Bese belandela njalo ukuze baqiniseke ukuthi bayayihlola imikhiqizo yabo futhi balandela imihlahlandlela efanele.Lesi ngesinye sezizathu eziningi zokuthi isitifiketi se-UL siyathandeka emabhizinisini.
Ngakho-ke ngokuyisisekelo i-UL iyisitifiketi esigunyazwe kakhulu ekuhlolweni kokuphepha nekhwalithi e-US Ngakho uma umkhiqizo usohlwini lwe-UL, kusho ukuthi umkhiqizo uphephile futhi usezingeni elihle, ngokuthi abantu bazimisele ukuwuthengisa futhi bawusebenzise ngaphandle kokukhathazeka.Yilokho okunengqondo.
Kungani i-UL idingeka ukuthengisa eNyakatho Melika?
Kungani isitifiketi se-UL sikhanga amabhizinisi?I-UL isichithe iminyaka engaphezu kwekhulu izakhela isithunzi futhi ifaka umuzwa wokwethembana.Uma umthengi ebona isitembu se-UL sokugunyazwa emkhiqizweni, cishe uzozizwa engcono ngokuwuthenga.
Isibonelo, uma othile ethengela i-circuit breaker entsha noma othintana naye, ukuqinisekiswa kwe-UL kungase kuthinte isinqumo sakhe.
Uma imikhiqizo noma amasevisi amabili afanayo ehambisana futhi eyodwa inesitifiketi se-UL kanti enye ingaqinisekisiwe, iyiphi ongayikhetha?Kubonisiwe ukuthi uphawu lwe-UL lungaba ithuluzi elinamandla lokumaketha lamabhizinisi, futhi abaningi babo balwela ukuthi imikhiqizo yabo ivunyelwe.Ilogo ye-UL inika umthengi ukuthula kwengqondo, kanye nebhizinisi uphawu lwasesidlangalaleni lokugunyaza.
Uma sibuyela emuva futhi sibheka ngalé kwesici sokumaketha, kuqondakala kabanzi ukuthi imishini iyonaimpilo yanoma yiliphi ibhizinisi.Ukuthatha izinyathelo zokuvikela lolu tshalomali kanye nabantu abalusebenzisayo kubalulekile empumelelweni yesikhathi eside yenkampani.Izimboni eziningi seziqalileklama imikhiqizo emishamayelana nezindinganiso zokuphepha ze-UL.
Ibhizinisi nabathengi bangazuza kanjani ekungeniseni imikhiqizo esohlwini lwe-UL?
1.Imvume ye-custom eshelelayo: ngesitifiketi se-UL, amasiko ase-US akhulula impahla ngokushesha, kodwa ngaphandle kwayo, kungase kube nokuhlolwa okude nokufiphele.
2.Uma kunengozi yezokuphepha, i-CPSC izohlulela ngokuthi ngabe umkhiqizo uqinisekisiwe nge-UL futhi, okungasiza ukugwema izinkinga ezidingekayo futhi kuphikisane nabathengisi abaningi kangaka abathengisa kuphela imikhiqizo enesitifiketi se-UL.
3.Ngesitifiketi se-UL kwandisa intando nokuqiniseka kwabasebenzisi bokugcina ukuthenga lo mkhiqizo kanye nabathengisi ukuze bathengise lo mkhiqizo.
4.Kuyasiza ukwandisa ukuthengisa.
5.Umphumela wokuthengisa ube lula futhi ngokushesha.
Ibhizinisi lokushaja i-Ev alilona elisha kodwa nakanjani, esigabeni sokuqala semboni yamandla entsha izinkampani eziningi ezibheke ukungena kulo mkhakha masha ebhizinisini, kulezi zimo, i-UL izokusiza nakanjani.
