I-UL sisifinyezo se-Underwriter Laboratories Inc. I-UL Safety Testing Institute yeyona inegunya eMelika kwaye yeyona nkampani inkulu yabucala ebandakanyeka kuvavanyo lokhuseleko kunye nokuchonga emhlabeni. Yintlangano ezimeleyo, eyenzela inzuzo, neyingcali eqhuba iimvavanyo zokhuseleko loluntu. Isebenzisa iindlela zovavanyo lwesayensi ukufunda nokufumanisa ukuba izixhobo ezahlukeneyo, izixhobo, iimveliso, izixhobo, izakhiwo, njl.njl. ziyingozi na kubomi nakwipropathi kunye nobungakanani bomonakalo; imisela, ibhala, kwaye ikhupha imigangatho ehambelanayo kwaye inceda ukunciphisa nokuthintela iingozi kubomi. Siza kuqokelela ulwazi ngomonakalo wepropathi kwaye senze uphando lokufumana inyani ngaxeshanye. Isatifikethi se-UL sisatifikethi esinganyanzelekanga eMelika. Ngokuyintloko sivavanya kwaye siqinisekisa ukusebenza kokhuseleko lwemveliso. Ububanzi besatifikethi sayo abubandakanyi iimpawu ze-EMC (ukuhambelana kwe-electromagnetic) zemveliso.
I-ETL luphawu olukhethekileyo lwe-Intertek, inkampani ephambili kwihlabathi leenkonzo zomgangatho nokhuseleko enembali eqala ngo-1896. Emva kokuba umsunguli omkhulu waseMelika u-Edison eseke i-Lamp Testing Bureau, wayitshintsha igama layo yaba yi-"Electrical Testing Laboratories" ngo-1904, eyaba yi-ETL yanamhlanje kwaye inodumo oluphezulu e-United States nakwihlabathi liphela. Ukusukela oko yasekwa kwiminyaka engaphezu kwekhulu eyadlulayo, i-ETL iye yaphuhliswa yaba yilabhoratri eyahlukeneyo kwaye idweliswe njengeLabhoratri yoVavanyo yeSizwe eQondisiweyo yi-US Federal Occupational Safety and Health Administration (OSHA). ILaboratri yoVavanyo-NRTL). Kwangaxeshanye, iBhunga leMigangatho laseKhanada-SCC likwaqaphela i-ETL njengeQumrhu loQinisekiso oluQinisekisiweyo kunye noMbutho woVavanyo oluQinisekisiweyo, kwaye liyayiqonda njengombutho ozimeleyo woqinisekiso lokhuseleko lwemveliso eCanada (ungangena kwiwebhusayithi ye-OSHA http://www.osha.gov ukuze ufumane ulwazi oluthe kratya).
Ukuba nje nayiphi na imveliso yombane, yoomatshini okanye ye-electromechanical inophawu lwe-ETL, oko kubonisa ukuba imveliso ihlangabezane neemfuno ezisezantsi zemigangatho yokhuseleko lwemveliso eyaziwayo ngokubanzi e-US naseKhanada. Ivavanyiwe yi-Intertek, iLabhoratri yoVavanyo oluQondisiweyo kuZwelonke (NRTL), kwaye iyahambelana nemigangatho yesizwe efanelekileyo; oko kuthetha ukuba ifektri yemveliso iyavuma ukuvavanywa rhoqo ukuqinisekisa ukuhambelana komgangatho wemveliso, onokuthengiswa kwiimarike zase-US naseKhanada. Oko kuthetha kubasasazi, abathengisi kunye nabathengi kukuba bathenga iimveliso ezivavanyiweyo kwaye zaqinisekiswa ngamaqela esithathu.
