Uyini umehluko phakathi kwesitifiketi se-FCC nesitifiketi se-UL?

1.Siyini isitifiketi se-FCC?
I-Federal Communications Commission (FCC) iyi-ejensi ezimele yoHulumeni wase-United States.Yasungulwa ngo-1934 ngesenzo seCongress of the United States, futhi iholwa yiCongress.Iningi lemikhiqizo yomsakazo, imikhiqizo yezokuxhumana kanye nemikhiqizo yedijithali idinga ukuqinisekiswa yi-FCC ukuze ingene emakethe yase-US.Isitifiketi se-FCC kuyimpoqo.
2.Siyini isitifiketi se-UL?
I-UL isifinyezo se-Underwriter Laboratories Inc. I-UL Safety Laboratory iyisikhungo esigunyaziwe e-United States kanye nesikhungo esizimele esikhudlwana esizibandakanya ekuhloleni ukuphepha kanye nokuhlonza emhlabeni.Kuyinhlangano ezimele, eyenza inzuzo eyenza ukuhlola ukuze kuphephe umphakathi.Isitifiketi se-UL yisitifiketi esingaphoqelekile e-United States, ikakhulukazi ukuhlola kanye nesitifiketi sokusebenza kokuphepha komkhiqizo, futhi ububanzi baso besitifiketi asibandakanyi izici ze-EMC (ukuhambelana kukagesi) zemikhiqizo.

3.Yini umehluko phakathi kwesitifiketi se-FCC nesitifiketi se-UL?
(1) Izidingo zokulawula: Isitifiketi se-FCC ngokusobala siyimpoqo njengesitifiketi esilawulayoimikhiqizo engenantambo e-United States;kodwa-ke, ukuqinisekiswa kwe-UL, okusukela kuwo wonke umkhiqizo kuya ezingxenyeni ezincane zomkhiqizo, kuzobandakanya lesi sitifiketi sokuphepha.

(2) Ububanzi bokuhlola: Isitifiketi se-FCC isivivinyo sokuhambisana nozibuthe kagesi, kodwa ukuhlolwa kwe-UL kuwukuhlola imithetho yokuphepha.

(3)Izimfuneko zamafekthri: Ukuqinisekiswa kwe-FCC akudingi ukuhlolwa kwefekthri, futhi akudingi ukuhlolwa konyaka;kodwa i-UL ihlukile, ayidingi nje kuphela ukuhlolwa kwefekthri kodwa futhi nokuhlolwa konyaka.

(4) I-ejensi ekhiphayo: I-ejensi ekhiphayo egunyazwe i-FCC yi-TCB.Inqobo nje uma i-ejensi yezitifiketi inokugunyazwa kwe-TCB, ingakhipha isitifiketi.Kodwa ku-UL, ngenxa yokuthi kuyinkampani yomshwalense yaseMelika, i-UL ingakhipha isitifiketi kuphela.

(5) Umjikelezo wesitifiketi: I-UL ibandakanya ukuhlolwa kwefekthri nezinye izici.Ngakho-ke, uma kuqhathaniswa, umjikelezo wesitifiketi se-FCC mfushane futhi izindleko zincane kakhulu.
