1.Yintoni isiqinisekiso seFCC?
I-Federal Communications Commission (FCC) yi-arhente ezimeleyo yorhulumente wase-United States.Yasekwa ngo-1934 ngesenzo seNkongolo yase-United States, kwaye ikhokelwa yiCongress.Uninzi lweemveliso zesicelo sikanomathotholo, iimveliso zonxibelelwano kunye neemveliso zedijithali kufuneka ziqinisekiswe yiFCC ukuze zingene kwimarike yaseMelika.Isatifikethi seFCC kunyanzelekile.
2.Yintoni isiqinisekiso seUL?
I-UL sisishunqulelo se-Underwriter Laboratories Inc. I-UL Safety Laboratory liziko eligunyazisiweyo e-United States kunye neziko labucala elikhulu elibandakanyeka kuvavanyo lokhuseleko kunye nokuchongwa kwihlabathi.Ngumbutho ozimeleyo, owenza ingeniso umbutho oqeqeshelweyo owenza imifuniselo yokhuseleko loluntu.isiqinisekiso se-UL sisiqinisekiso esingesosinyanzelo e-United States, ngakumbi uvavanyo kunye nesiqinisekiso sokusebenza kokhuseleko lwemveliso, kwaye umda wesiqinisekiso awubandakanyi iimpawu ze-EMC (ukuhambelana kombane) kweemveliso.
3.Nguwuphi umahluko phakathi kwesatifikethi seFCC kunye nesiqinisekiso seUL?
(1) Iimfuno zolawulo: Isiqinisekiso seFCC ngokucacileyo sinyanzelekile njengesiqinisekiso solawuloiimveliso ezingenazingcingo eUnited States;nangona kunjalo, isiqinisekiso se-UL, esisuka kwimveliso yonke ukuya kwiindawo ezincinci zemveliso, siya kubandakanya esi siqinisekiso sokhuseleko.
(2) Uvavanyo lomda: Ukuqinisekiswa kweFCC luvavanyo lokuhambelana kwe-electromagnetic, kodwa uvavanyo lwe-UL luvavanyo lwemithetho yokhuseleko.
(3) Iimfuno zeefektri: Isiqinisekiso seFCC asifuni uphicotho-zincwadi lwefektri, kwaye ayifuni naluphi na uhlolo lonyaka;kodwa i-UL yahlukile, ayifuni kuphela uphicotho lwefektri kodwa kunye nokuhlolwa konyaka.
(4) I-arhente ekhuphayo: I-arhente ekhuphayo eqinisekisiwe yi-FCC yi-TCB.Ngethuba nje i-arhente yoqinisekiso inogunyaziso lwe-TCB, inokukhupha isatifikethi.Kodwa kwi-UL, kuba yinkampani yeinshurensi yaseMelika, i-UL inokukhupha kuphela isatifikethi.
(5) Umjikelo wesatifikethi: I-UL ibandakanya ukuhlolwa kwefektri kunye neminye imiba.Ke ngoko, xa sithelekisa, umjikelo wesatifikethi seFCC mfutshane kwaye iindleko zincinci kakhulu.
