Isatifikethi se-UL sisiqinisekiso esingesosinyanzelo e-United States, ngakumbi uvavanyo kunye nokuqinisekiswa kokusebenza kokhuseleko lwemveliso, kwaye umda wesiqinisekiso awubandakanyi iimpawu ze-EMC (ukuhambelana kombane) kwiimveliso.I-UL ngumbutho ozimeleyo, ongenzi nzuzo, umbutho oqeqeshiweyo ovavanya ukhuseleko loluntu.I-UL yasungulwa kwi-1894. Kwinqanaba lokuqala, i-UL yayixhomekeke kakhulu kwiimali ezinikezelwa yi-inshurensi yomlilo ukuze kugcinwe ukusebenza kwayo.Kwada kwangowe-1916 apho i-UL yayizimele ngokupheleleyo.Emva kweminyaka ephantse ibe yikhulu yophuhliso, i-UL iye yaba ngumbutho woqinisekiso owaziwayo kwihlabathi kunye nesethi yeenkqubo ezingqongqo zolawulo lombutho, uphuhliso olusemgangathweni kunye neenkqubo zokuqinisekisa imveliso.
Isatifikethi se-UL sisekelwe kwisatifikethi, i-arhente yophuhliso olusemgangathweni, i-arhente ye-arhente, i-arhente ye-arhente.I-1894, kunye ne-UL ikwangumphuhlisi wemigangatho yelizwe laseKhanada.
Ukufumana iSatifikethi se-UL kubalulekile kuba sibonisa ubuchule bomenzi kunye nababoneleli ngenkonzo.Abathengi bafuna ukwazi ukuba inkampani abayiqeshileyo ukufaka izixhobo zabo ikufanele ukwenza umsebenzi ngokufanelekileyo, kwaye bathathe ixesha lokuqinisekisa ukuba zonke iimveliso abazifakileyo ziyavavanywa kwaye ziyahlangabezana nemigangatho yokhuseleko.Isatifikethi se-UL sikwabonisa ukuba inkampani idibana nayo yonke imimandla yokhuseleko lwasekhaya kunye ne-federal kunye nemimiselo yokusingqongileyo.Unokuqiniseka ukuba uyazi ukuba abasebenzi bakho kunye nabathengi bakhuselekile.
I-UL yokuQinisekisa uphawu ibonelela ngeenjongo, uvavanyo lweqela lesithathu olusekwe kwisayensi kunye nokuqinisekiswa kwamabango okuthengisa abavelisi kwiimveliso zabo, ezifana nokusebenza kwemveliso, umgangatho, kunye namabango omsebenzi.
1. Imveliso ithatha iintlobo ezahlukeneyo zokhuseleko lwemveliso;xa abathengi kunye neeyunithi zikhetha ukuqinisekiswa kwemveliso yase-US, kulungele ukukhetha amanqaku emveliso kunye nemarike yonke.
2. Imbali ye-UL inembali engaphezu kweminyaka eyi-100.Umfanekiso wakho ugxile kakhulu kubathengi nakurhulumente.Ukuba awuthengisi iimveliso kubathengi, ngokuqinisekileyo uya kufuna ukuba iimveliso zibe nesatifikethi se-UL, ukuze iimveliso ziphindwe.
3. Abathengi baseMelika kunye neeyunithi zokuthenga banokuzithemba ngakumbi kwiimveliso zenkampani.
4. Kukho ngaphezu kwama-40,000 ezithili zolawulo e-United States federal, state, county, and municipal governments, all the reception mark of certification mark .
Isiqinisekiso se-UL esifunyenwe ziimveliso zeSoloon sibaluleke kakhulu ekuthengisweni kweemveliso zethu eMelika, eCanada nakwamanye amazwe.
