UL ndiye chidule cha Underwriter Laboratories Inc. UL Safety Testing Institute ndi yovomerezeka kwambiri ku United States komanso bungwe lalikulu kwambiri labizinesi lomwe likuchita kuyezetsa chitetezo ndi kuzindikira padziko lonse lapansi. Ndi bungwe lodziyimira pawokha, lochita phindu, laukadaulo lomwe limachita zoyeserera pofuna kuteteza anthu. Amagwiritsa ntchito njira zoyesera zasayansi kuti aphunzire ndikuzindikira ngati zida zosiyanasiyana, zida, zida, zida, nyumba, ndi zina zotere zili zovulaza moyo ndi katundu komanso kuchuluka kwa zovulaza; imatsimikizira, kulemba, ndi kutulutsa miyezo yolingana ndikuthandizira kuchepetsa ndi kupewa zoopsa pamoyo. Tidzasonkhanitsa zambiri za kuwonongeka kwa katundu ndikuchita kafukufuku wofufuza nthawi yomweyo. Satifiketi ya UL ndi chiphaso chosakakamiza ku United States. Imayesa ndikutsimikizira magwiridwe antchito achitetezo cha mankhwala. Kukula kwake kwa certification sikuphatikiza mawonekedwe a EMC (electromagnetic compatibility) azinthu.
ETL ndiye chizindikiro chokhacho cha EUROLAB, kampani yotsogola padziko lonse lapansi yachitetezo chamtundu ndi chitetezo yomwe ili ndi mbiri yakale kuyambira 1896. Woyambitsa wamkulu waku America Edison atayambitsa Lamp Testing Bureau, adasintha dzina lake kukhala "Electrical Testing Laboratories" mu 1904. idakhala ETL yamasiku ano ndipo imakhala ndi mbiri yabwino ku United States komanso padziko lonse lapansi. Chiyambireni kukhazikitsidwa kwake zaka zoposa zana zapitazo, ETL yakhala malo opangira ma labotale osiyanasiyana ndipo yalembedwa ngati National Recognized Testing Laboratory ndi US Federal Occupational Safety and Health Administration (OSHA). Kuyesa Laboratory-NRTL). Nthawi yomweyo, Bungwe la Standards Council of Canada-SCC limazindikiranso ETL ngati Bungwe Lovomerezeka Lovomerezeka ndi Bungwe Loyesa Lovomerezeka, ndipo limazindikira kuti ndi bungwe lodziyimira pawokha lachitetezo chachitetezo chazinthu ku Canada (mutha kulowa patsamba la OSHA http:/ /www.osha.gov kuti mudziwe zambiri).
Malingana ngati chinthu chilichonse chamagetsi, chamakina kapena chamagetsi chimakhala ndi chizindikiro cha ETL, zikuwonetsa kuti chinthucho chakwaniritsa zofunikira zodziwika bwino zachitetezo chazinthu zaku US ndi Canada. Yayesedwa ndi EUROLAB, Nationally Recognized Testing Laboratory (NRTL), ndipo ikugwirizana ndi Miyezo Yoyenera yadziko; zimatanthauzanso kuti fakitale yopanga ikuvomera kuyang'aniridwa mosamalitsa nthawi zonse kuti zitsimikizire kusasinthika kwamtundu wazinthu, zomwe zitha kugulitsidwa kumisika yaku US ndi Canada. Zomwe zimatanthawuza kwa ogulitsa, ogulitsa ndi ogula ndikuti akugula zinthu zomwe zayesedwa ndikutsimikiziridwa ndi anthu ena.
