I-UL isifinyezo se-Underwriter Laboratories Inc. I-UL Safety Testing Institute inegunya elikhulu e-United States futhi iyisikhungo esizimele esikhulu kunazo zonke esizibandakanya nokuhlola ukuphepha kanye nokuhlonza emhlabeni. Kuyinhlangano ezimele, eyenzela inzuzo, nephrofeshinali eyenza izivivinyo zokuvikela umphakathi. Isebenzisa izindlela zokuhlola zesayensi ukuze itadishe futhi inqume ukuthi ingabe izinto ezihlukahlukene, izisetshenziswa, imikhiqizo, amathuluzi, izakhiwo, njll. ziyingozi yini empilweni nasempahleni kanye nezinga lokulimala; inquma, ibhale, futhi ikhiphe izindinganiso ezihambisanayo futhi isize ekunciphiseni nasekuvimbeleni izingozi ekuphileni. Sizoqoqa ulwazi ngomonakalo wempahla futhi senze ucwaningo lokuthola iqiniso ngesikhathi esifanayo. Isitifiketi se-UL isitifiketi esingaphoqelekile e-United States. Ihlola kakhulu futhi iqinisekise ukusebenza kokuphepha komkhiqizo. Ububanzi bayo bokunikeza isitifiketi akubandakanyi izici ze-EMC (ukuhambisana kwe-electromagnetic) zomkhiqizo.
I-ETL iwuphawu olukhethekile lwe-Intertek, inkampani ehamba phambili emhlabeni yezinkonzo zekhwalithi nezokuphepha enomlando osukela ku-1896. Ngemva kokuba umsunguli omkhulu waseMelika u-Edison esungule i-Lamp Testing Bureau, wayishintsha igama yaba “Ilabhorethri Yokuhlola Ugesi” ngo-1904, okwathi ngemva kwalokho wasungula i-Lamp Testing Bureau. yaba yi-ETL yanamuhla futhi ijabulela idumela eliphezulu e-United States nasemhlabeni jikelele. Kusukela yasungulwa eminyakeni engaphezu kwekhulu edlule, i-ETL isithuthuke yaba ilabhorethri ehlukahlukene futhi isifakwe ohlwini lweLabhorethri Yokuhlola Eyaziwa Kazwelonke yi-US Federal Occupational Safety and Health Administration (OSHA). Ilabhorethri Yokuhlola-NRTL). Ngaso leso sikhathi, i-Standard Council yase-Canada-SCC iphinde ibone i-ETL njengeSigungu Esigunyazwe Sezitifiketi kanye Nenhlangano Yokuhlola Egunyaziwe, futhi iyayibona njengenhlangano ezimele yesitifiketi sokuphepha komkhiqizo e-Canada (ungangena ngemvume kuwebhusayithi ye-OSHA http://www.osha.com/ /www.osha.gov ukuthola eminye imininingwane).
Inqobo nje uma noma yimuphi umkhiqizo kagesi, womshini noma kagesi unophawu lwe-ETL, kukhombisa ukuthi umkhiqizo uhlangabezane nezimfuneko eziphansi zamazinga ajwayelekile okuphepha emikhiqizo yase-US kanye ne-Canadian. Ihlolwe yi-Intertek, Ilabhorethri Yokuhlola Eyaziwa Kuzwelonke (NRTL), futhi ithobelana namazinga kazwelonke Abalulekile; kusho futhi ukuthi imboni yokukhiqiza iyavuma ukuhlolwa njalo okuqinile ukuze kuqinisekiswe ukuhambisana kwekhwalithi yomkhiqizo, ongathengiswa e-US kanye nezimakethe zaseCanada. Okushiwo kubasabalalisi, abathengisi kanye nabathengi ukuthi bathenga imikhiqizo ehloliwe futhi yaqinisekiswa ngabantu besithathu.
