isiqinisekiso se-UL
I-UL sisishunqulelo se-Underwriters Laboratories yaseMelika. IZiko loVavanyo loKhuseleko lwe-UL lelona linegunya eUnited States kunye nombutho omkhulu wabucala obandakanyeka kuvavanyo lokhuseleko kunye novavanyo kwihlabathi. Ngumbutho ozimeleyo, onengeniso yobuchwephesha oqhuba imifuniselo yokhuseleko loluntu. Isebenzisa iindlela zovavanyo lwezenzululwazi ukufunda nokumisela ukuba ngaba izinto ezahlukeneyo, izixhobo, iimveliso, izixhobo, izakhiwo, njl.njl. ziyingozi kubomi nakwipropathi kunye nenqanaba lokwenzakala; ukumisela, ukuqokelela kunye nokukhupha imigangatho ehambelanayo kunye nokunceda ukunciphisa kunye nokuthintela ubomi Idatha yelahleko yepropati, ngelixa uqhuba ishishini lophando lophando.

Iimveliso ezininzi zesicelo sikanomathotholo, iimveliso zonxibelelwano, kunye neemveliso zedijithali zifuna imvume yeFCC ukungena kwimarike yase-US. Ikomiti yeFCC iphanda kwaye iphonononge amanqanaba ahlukeneyo okhuseleko lwemveliso ukuze kufumaneke eyona ndlela yokusombulula ingxaki. Kwangaxeshanye, iFCC ikwabandakanya ukuvavanywa kwezixhobo zikanomathotholo kunye neenqwelomoya.
