I-UL sisishunqulelo se-Underwriter Laboratories Inc. Iziko loVavanyo loKhuseleko lwe-UL lelona ligunyazisiweyo e-United States kunye neziko labucala likhulu elibandakanyeka kuvavanyo lokhuseleko kunye nokuchongwa kwihlabathi. Ngumbutho ozimeleyo, owenza inzuzo, umbutho oqeqeshelweyo owenza imifuniselo yokhuseleko loluntu. Isebenzisa iindlela zovavanyo lwezenzululwazi ukufunda kunye nokuqinisekisa ukuba izixhobo ezahlukeneyo, izixhobo, iimveliso, izixhobo, izakhiwo, njl.njl. ziyingozi kubomi kunye nepropathi kunye nenqanaba lokwenzakala; imisela, ibhala, kwaye ikhuphe imigangatho ehambelanayo kwaye inceda ukunciphisa nokuthintela iingozi ebomini. Siya kuqokelela ulwazi ngomonakalo wepropati kwaye siqhube uphando lokufumana inyaniso ngexesha elifanayo. Isatifikethi se-UL sisiqinisekiso esinganyanzelisiyo e-United States. Ikakhulu ivavanya kwaye iqinisekisa ukusebenza kokhuseleko lwemveliso. Umda wokuqinisekiswa kwayo awubandakanyi i-EMC (ukuhambelana kombane wombane) iimpawu zemveliso.
I-ETL luphawu olukhethekileyo lwe-Intertek, eyona nkampani iphambili ehlabathini yeenkonzo ezisemgangathweni nokhuseleko enembali esusela kwi-1896. Emva kokuba umqambi omkhulu waseMelika u-Edison eseke i-Bureau yoVavanyo lweLamp, wayitshintsha igama layo yaba yi-“Electrical Testing Laboratories” ngo-1904, eyathi. yaba yi-ETL yanamhlanje kwaye yonwabela udumo oluphezulu eUnited States nakwihlabathi liphela. Ukusukela ekusekweni kwayo ngaphezu kwekhulu leminyaka eyadlulayo, i-ETL iye yaphuhliswa yaba yilabhoratri eyohlukeneyo kwaye idweliswe njengeLebhu yeSizwe yoVavanyo eyaMkelweyo yi-US Federal Occupational Safety and Health Administration (OSHA). ILebhu yoVavanyo-NRTL). Kwangaxeshanye, iBhunga leMigangatho yaseCanada-SCC ikwaqaphela i-ETL njengeSigqeba esiQinisekisiweyo esiQinisekisiweyo kunye noMbutho woVavanyo oluVunyiweyo, kwaye uyayibona njengombutho ozimeleyo wokuqinisekisa ukhuseleko lwemveliso eCanada (ungangena kwiwebhusayithi ye-OSHA http:/ /www.osha.gov ngolwazi olungakumbi).
Logama nje nayiphi na imveliso yombane, yomatshini okanye ye-electromechanical inophawu lwe-ETL, oko kubonisa ukuba imveliso ihlangabezane neemfuno ezisezantsi ezivunyiweyo ngokubanzi zemigangatho yokhuseleko lwemveliso yase-US kunye ne-Canadian. Ivavanywe yi-Intertek, iLabhoratri yoVavanyo eQhelekileyo kuZwelonke (NRTL), kwaye ithobela imigangatho yesizwe eFanelekileyo; kukwathetha ukuba umzi-mveliso wemveliso uyavuma ukuhlolwa rhoqo ngokungqongqo ukuqinisekisa ukuhambelana komgangatho wemveliso, enokuthengiswa kwi-US kunye neemarike zaseKhanada. Kuthetha ntoni kubathengisi, abathengisi kunye nabathengi kukuba bathenga iimveliso ezivavanyiweyo kwaye zaqinisekiswa ngabantu besithathu.
