▍Yintoni iSatifikethi se-CB?

I-IECEE CB yinkqubo yokuqala yokwenyani yamazwe ngamazwe yokwamkelwa ngokufanayo kweengxelo zovavanyo lokhuseleko lwezixhobo zombane. I-NCB (i-National Certification Body) ifikelela kwisivumelwano samazwe amaninzi, esenza ukuba abavelisi bafumane isatifikethi sesizwe kwamanye amazwe angamalungu phantsi kwe-CB scheme ngesiseko sokudlulisela esinye sezatifikethi ze-NCB.

Isatifikethi se-CB luxwebhu lwesikimu se-CB esisemthethweni esikhutshwe yi-NCB egunyazisiweyo, ekwazisa enye i-NCB ukuba iisampuli zemveliso ezivavanyiweyo ziyahambelana neemfuno ezisemgangathweni.

Njengohlobo lwengxelo esemgangathweni, ingxelo ye-CB idwelisa iimfuno ezifanelekileyo ukusuka kwinqaku le-IEC elisemgangathweni ngento. Ingxelo ye-CB ayinikezi kuphela iziphumo zazo zonke iimvavanyo ezifunekayo, ukulinganisa, ukuqinisekiswa, ukuhlolwa kunye nokuhlola ngokucacileyo kunye nokungacacisi, kodwa kubandakanywa neefoto, umzobo wesiphaluka, imifanekiso kunye nenkcazo yemveliso. Ngokomgaqo weskim se-CB, ingxelo yeCB ayizukusebenza de iveze nesatifikethi seCB kunye.

▍Kutheni sifuna iSiqinisekiso se-CB?

1. Ngqolyukuqondazed or imvumeedngeilunguamazwe

Ngesatifikethi se-CB kunye nengxelo yovavanyo lwe-CB, iimveliso zakho zinokuthunyelwa kumazwe athile ngokuthe ngqo.

1. Guqulela kwamanye amazwe izatifikethi

Isatifikethi se-CB sinokuguqulwa ngokuthe ngqo kwisatifikethi samazwe angamalungu ayo, ngokubonelela ngesatifikethi se-CB, ingxelo yovavanyo kunye nengxelo yokuvavanya umahluko (xa kufanelekile) ngaphandle kokuphinda uvavanyo, olunokunciphisa ixesha eliphambili lokuqinisekiswa.

1. Qinisekisa uKhuseleko lweMveliso

Uvavanyo lwesiqinisekiso se-CB luqwalasela ukusetyenziswa okufanelekileyo kwemveliso kunye nokhuseleko olubonakalayo xa lusetyenziswa kakubi. Imveliso eqinisekisiweyo ingqina ukuba iyanelisa iimfuno zokhuseleko.

▍Kutheni i-MCM?

● Isiqinisekiso:I-MCM yeyokuqala egunyazisiweyo ye-CBTL ye-IEC 62133 isiqinisekiso esisemgangathweni yiTUV RH kwilizwe laseTshayina.

● Isatifikethi kunye namandla okuvavanya:I-MCM iphakathi kwepatch yokuqala yovavanyo kunye nesiqinisekiso somntu wesithathu kumgangatho we-IEC62133, kwaye igqibe ngaphezu kwe-7000 yokuvavanya ibhetri ye-IEC62133 kunye neengxelo ze-CB kubathengi behlabathi.

● Inkxaso yobugcisa:I-MCM ineenjineli ezingaphezu kwe-15 zobuchwephesha ezikhethekileyo kuvavanyo ngokomgangatho we-IEC 62133. I-MCM ibonelela abathengi ngolwazi olubanzi, oluchanekileyo, oluvaliweyo lwenkxaso yobugcisa kunye neenkonzo zolwazi oluphambili.

Umgangatho onyanzelekileyo weSizwe waseTshayinaGB 4943.1-2022, i-Audio / ividiyo, izixhobo zeteknoloji yolwazi kunye nonxibelelwano Icandelo 1: Iimfuno zokhuseleko, zakhululwa ngoJulayi 19. Umgangatho ubhekisela kumgangatho wamazwe ngamazwe we-IEC 62368-1: 2018, kukho ezimbini eziphambili eziphuculweyo ezibalaseleyo: kwelinye icala, ububanzi besicelo sandiswa ngakumbi, inguqu entsha yomgangatho idibanisa imigangatho yesizwe enyanzelekileyo ye-GB 4943.1-2011 yoKhuseleko lweTekhnoloji yoLwazi lweSixhobo seCandelo 1: IiMfuno eziBanzi kunye ne-GB 8898-2011 i-Audio, iVidiyo kunye neeMfuno zoKhuseleko lweZixhobo zoMbane ezifanayo, ezigubungela zonke. iimveliso zeaudio, ividiyo, ulwazi kunye nezixhobo zobuchwepheshe bonxibelelwano; kwelinye icala, kukho ubuchule kunye nokuphucula. Inguqu entsha yomgangatho iphakamisa ingcamango yobunjineli bokhuseleko, iphakamisa ukuhlelwa kwamandla, kwaye ithathela ingqalelo ngokulandelayo iintlobo ezintandathu zemithombo yengozi: ukulimala okubangelwa ngumbane, umlilo obangelwa ngumbane, ukulimala okubangelwa izinto ezinobungozi, ukulimala okubangelwa oomatshini, ukutsha kwe-thermal, isandi kunye nemitha yokukhanya, kwaye ubeke phambili iimfuno ezihambelanayo zokhuseleko kunye neendlela zokuvavanya.
 Umda wokusetyenziswa kwemigangatho emibini wahlukile. Umda womgangatho omtsha we-GB 4943 wesizwe uya kudibanisa inguqulo yangaphambili ye-GB 4943.1-2011 kunye ne-GB 8898-2011, equka iindidi ezintathu zezixhobo, izixhobo zeaudio kunye nevidiyo, izixhobo zeteknoloji yolwazi, izixhobo zeteknoloji yonxibelelwano, esihlala sisithi "imveliso ye-elektroniki ”.
