I-UL 11627 ikhebula elixhumayo lohlelo lokugcina amandla eliphumelele isitifiketi somkhiqizo we-UL wezinga laseMelika. Ngokuvamile isetshenziswa kakhulu ezintweni zasendlini, ihlinzeka ngemikhiqizo ephephile nethembekile yekhwalithi ephezulu, iqinisekisa ukuphuma okuphephile kukagesi kanye nokuhlinzeka ngokuphuma kwamandla okuphephile ezintweni zikagesi. Imishini yangaphakathi yezimoto ihlinzeka ngezintambo eziphephile nezithembekile nemikhiqizo yekhebula yazo zonke izinkambu zezimoto ezinamandla omkhiqizo wobuchwepheshe ukuze kuqinisekiswe ukuphuma okusebenzayo kwamandla emoto. Amaphaneli elanga, agxile ocwaningweni nasekuthuthukisweni emikhakheni yobuchwepheshe obuphezulu, enza ngobuhlakani ikhwalithi yomkhiqizo ukuze ahlangabezane nesidingo sikagesi emikhakheni ehlukahlukene futhi aqinisekise ukusebenza okuphephile kwephrojekthi.
