▍Siyini Isitifiketi Se-CB?

I-IECEE CB iwuhlelo lokuqala lwangempela lwamazwe ngamazwe lokuqashelwa ngokufanayo kwemibiko yokuhlolwa kokuphepha kwezinto zikagesi. I-NCB (National Certification Body) ifinyelela isivumelwano sezizwe eziningi, esivumela abakhiqizi ukuthi bathole isitifiketi sikazwelonke kwamanye amazwe angamalungu ngaphansi kohlelo lwe-CB ngesisekelo sokudlulisa esinye sezitifiketi ze-NCB.

Isitifiketi se-CB siwumbhalo osemthethweni wohlelo lwe-CB okhishwe i-NCB egunyaziwe, okokwazisa enye i-NCB ukuthi amasampula omkhiqizo ohloliwe ahambisana nezidingo ezijwayelekile.

Njengohlobo lombiko omisiwe, umbiko we-CB ubala izidingo ezifanele ezivela entweni ejwayelekile ye-IEC ngento ngayinye. Umbiko we-CB awuhlinzeki nje kuphela ngemiphumela yakho konke ukuhlolwa okudingekile, ukukalwa, ukuqinisekiswa, ukuhlolwa nokuhlola ngokucacile nokungacacisi, kodwa futhi kufaka phakathi izithombe, umdwebo wesifunda, izithombe nencazelo yomkhiqizo. Ngokomthetho wohlelo lwe-CB, umbiko we-CB ngeke usebenze kuze kube yilapho wethula isitifiketi se-CB ndawonye.

▍Kungani sidinga Isitifiketi se-CB?

1. Ngqolyqaphelazed or vumaedngeilunguamazwe

Ngesitifiketi se-CB kanye nombiko wokuhlola we-CB, imikhiqizo yakho ingathunyelwa kwamanye amazwe ngokuqondile.

1. Guqulela kwamanye amazwe izitifiketi

Isitifiketi se-CB singaguqulelwa ngokuqondile kusitifiketi samazwe angamalungu ayo, ngokunikeza isitifiketi se-CB, umbiko wokuhlola kanye nombiko wokuhlola umehluko (uma kusebenza) ngaphandle kokuphinda ukuhlolwa, okunganciphisa isikhathi sokuhola sokuthola isitifiketi.

1. Qinisekisa Ukuphepha Komkhiqizo

Ukuhlolwa kwesitifiketi se-CB kubheka ukusetshenziswa okuphusile komkhiqizo kanye nokuphepha okubonakalayo uma usetshenziswa kabi. Umkhiqizo oqinisekisiwe ufakazela ukugculisa kwezidingo zokuphepha.

▍Kungani i-MCM?

● Ukufaneleka:I-MCM iyi-CBTL yokuqala egunyaziwe ye-IEC 62133 ejwayelekile yi-TUV RH ezweni laseChina.

● Isitifiketi namandla okuhlola:I-MCM iphakathi kwesiqephu sokuqala sokuhlola nesitifiketi senkampani yangaphandle ye-IEC62133 ejwayelekile, futhi isiqede ukuhlola amabhethri e-IEC62133 angaphezu kuka-7000 kanye nemibiko ye-CB kumakhasimende omhlaba.

● Usekelo lobuchwepheshe:I-MCM inonjiniyela bezobuchwepheshe abangaphezu kwe-15 abakhethekile ekuhlolweni njengokujwayelekile kwe-IEC 62133. I-MCM ihlinzeka amakhasimende ngohlobo oluphelele, olunembile, oluvaliwe losekelo lobuchwepheshe kanye nezinsizakalo zolwazi ezihola phambili.

I-Chinese National mandatory standardI-GB 4943.1-2022, I-Audio/video, imishini yobuchwepheshe bolwazi nokuxhumana Ingxenye 1: Izidingo zokuphepha, ikhishwe ngoJulayi 19. Izinga libhekisela ezingeni lamazwe ngamazwe le-IEC 62368-1:2018, kukhona ukuthuthukiswa okubalulekile okubili okubalulekile: ngakolunye uhlangothi, ububanzi bokufaka isicelo buye banwetshwa, inguqulo entsha yezinga ihlanganisa izindinganiso kazwelonke eziyisibopho zangempela ze-GB 4943.1-2011 Equipment Security Equipment Ingxenye 1: Izidingo Ezivamile kanye ne-GB 8898-2011 Izidingo Zokuvikeleka Kwezisetshenziswa Ze-elekthronikhi ezifanayo, ezihlanganisa konke. imikhiqizo yemishini yokulalelwayo, yevidiyo, yolwazi kanye nezokuxhumana; ngakolunye uhlangothi, kukhona ubuchwepheshe bokwenza ngcono nokuthuthukisa. Inguqulo entsha yezinga iphakamisa umqondo wobunjiniyela bokuphepha, iphakamisa ukuhlukaniswa kwamandla, futhi icabangela ukulandela izinhlobo eziyisithupha zemithombo yengozi: ukulimala okubangelwa ugesi, umlilo obangelwa ugesi, ukulimala okubangelwa izinto eziyingozi, ukulimala okubangelwa imishini, ukushisa okushisayo, imisebe yomsindo nelula, futhi ubeke phambili izidingo zokuphepha ezihambisanayo nezindlela zokuhlola.
 Ububanzi bokusebenza bezindinganiso ezimbili buhlukile. Ububanzi bezinga lezwe elisha le-GB 4943 lizohlanganisa inguqulo yangaphambilini ye-GB 4943.1-2011 kanye ne-GB 8898-2011, ehlanganisa izigaba ezintathu zemishini, imishini yomsindo nevidiyo, imishini yobuchwepheshe bolwazi, imishini yobuchwepheshe bezokuxhumana, esivame ukuthi "imikhiqizo kagesi ”.
