Ndi bungwe lodziyimira pawokha, lochita phindu, komanso laukadaulo lomwe limachita zoyeserera zachitetezo cha anthu. Limagwiritsa ntchito njira zoyesera zasayansi kuti liphunzire ndikuwona ngati zipangizo zosiyanasiyana, zida, zinthu, zida, nyumba, ndi zina zotero zili zovulaza moyo ndi katundu komanso kuchuluka kwa kuwonongeka; limazindikira, kulemba, ndikupereka miyezo yogwirizana ndi izi ndipo limathandiza kuchepetsa ndikupewa zoopsa pamoyo. Tidzasonkhanitsa zambiri zokhudza kuwonongeka kwa katundu ndikuchita kafukufuku wofufuza nthawi imodzi. Satifiketi ya UL ndi satifiketi yosakakamiza ku United States. Makamaka imayesa ndikutsimikizira magwiridwe antchito achitetezo cha chinthu. Chiwerengero chake cha satifiketi sichiphatikizapo mawonekedwe a EMC (electromagnetic compatibility) a chinthucho.
ETL ndi chizindikiro chapadera cha Intertek, kampani yotsogola padziko lonse lapansi yopereka chithandizo chapamwamba komanso chitetezo kuyambira mu 1896. Wopanga wamkulu waku America, Edison, atakhazikitsa Lamp Testing Bureau, adasintha dzina lake kukhala "Electrical Testing Laboratories" mu 1904, yomwe idakhala ETL ya masiku ano ndipo ili ndi mbiri yabwino ku United States ndi padziko lonse lapansi. Kuyambira pomwe idakhazikitsidwa zaka zoposa zana zapitazo, ETL yakhala labotale yosiyanasiyana ndipo yalembedwa ngati National Recognised Testing Laboratory ndi US Federal Occupational Safety and Health Administration (OSHA). Testing Laboratory-NRTL). Nthawi yomweyo, Standards Council of Canada-SCC imazindikiranso ETL ngati Accredited Certification Body komanso Accredited Testing Organisation, ndipo imazindikira ngati bungwe lodziyimira pawokha lopereka chitsimikizo cha chitetezo cha zinthu ku Canada (mutha kulowa patsamba la OSHA http://www.osha.gov kuti mudziwe zambiri).
Malinga ngati chinthu chilichonse chamagetsi, chamakina kapena chamagetsi chili ndi chizindikiro cha ETL, zimasonyeza kuti chinthucho chakwaniritsa zofunikira zochepa za miyezo yodziwika bwino ya chitetezo cha zinthu ku US ndi Canada. Chayesedwa ndi Intertek, Nationally Recognised Testing Laboratory (NRTL), ndipo chikutsatira miyezo yoyenera yadziko lonse; zimatanthauzanso kuti fakitale yopanga ivomereza kuyendera mosamala nthawi zonse kuti itsimikizire kuti khalidwe la chinthucho ndi lofanana, lomwe lingagulitsidwe kumisika ya US ndi Canada. Zomwe zikutanthauza kwa ogulitsa, ogulitsa ndi ogula ndikuti akugula zinthu zomwe zayesedwa ndi kutsimikiziridwa ndi anthu ena.
