I-UL isifinyezo se-Underwriter Laboratories Inc. I-UL Safety Testing Institute iyisikhungo esinegunya elikhulu e-United States futhi iyisikhungo esikhulu kunazo zonke esizimele esibandakanyeka ekuhlolweni nasekuhlonzeni ukuphepha emhlabeni. Yinhlangano ezimele, eyenzela inzuzo, neyobungcweti eqhuba izivivinyo zokuphepha komphakathi. Isebenzisa izindlela zokuhlola zesayensi ukutadisha nokunquma ukuthi izinto ezahlukene, amadivayisi, imikhiqizo, imishini, izakhiwo, njll. ziyingozi yini empilweni nasempahleni kanye nezinga lokulimala; inquma, ibhala, futhi ikhiphe amazinga ahambisanayo futhi isiza ekunciphiseni nasekuvimbeleni izingozi empilweni. Sizoqoqa ulwazi ngomonakalo wempahla futhi senze ucwaningo lokuthola amaqiniso ngesikhathi esifanayo. Isitifiketi se-UL siyisitifiketi esingaphoqelekile e-United States. Ngokuyinhloko sihlola futhi siqinisekisa ukusebenza kokuphepha komkhiqizo. Ububanzi baso bokuqinisekiswa abufaki izici ze-EMC (ukuhambisana kwe-electromagnetic) zomkhiqizo.
I-ETL iwuphawu olukhethekile lwe-Intertek, inkampani ehamba phambili emhlabeni yezinsizakalo zekhwalithi nokuphepha enomlando osukela ku-1896. Ngemva kokuba umsunguli omkhulu waseMelika u-Edison esungule i-Lamp Testing Bureau, washintsha igama layo laba “i-Electrical Testing Laboratories” ngo-1904, eyaba yi-ETL yanamuhla futhi inedumela eliphezulu e-United States nasemhlabeni jikelele. Selokhu yasungulwa eminyakeni engaphezu kwekhulu edlule, i-ETL isithuthuke yaba yilabhorethri ehlukahlukene futhi ibhalwe njenge-National Recognised Testing Laboratory yi-US Federal Occupational Safety and Health Administration (OSHA). I-Testing Laboratory-NRTL). Ngesikhathi esifanayo, i-Standards Council of Canada-SCC nayo iyaqaphela i-ETL njenge-Accredited Certification Body kanye ne-Accredited Testing Organisation, futhi iyaqaphela njengenhlangano ezimele yokuqinisekisa ukuphepha komkhiqizo eCanada (ungangena kwiwebhusayithi ye-OSHA http://www.osha.gov ukuthola ulwazi olwengeziwe).
Uma nje noma yimuphi umkhiqizo kagesi, wemishini noma we-elekthronikhi unophawu lwe-ETL, kubonisa ukuthi umkhiqizo uhlangabezane nezidingo ezincane zezindinganiso zokuphepha zomkhiqizo zase-US nezaseCanada eziqashelwa kabanzi. Uhlolwe yi-Intertek, i-Nationally Recognised Testing Laboratory (NRTL), futhi uhambisana nezindinganiso zikazwelonke ezifanele; kusho nokuthi ifektri yokukhiqiza iyavuma ukuhlolwa njalo ukuqinisekisa ukuvumelana kwekhwalithi yomkhiqizo, engathengiswa ezimakethe zase-US nezaseCanada. Okushoyo kubasabalalisi, abathengisi kanye nabathengi ukuthi bathenga imikhiqizo ehlolwe futhi yaqinisekiswa yizinkampani zangaphandle.
