▍Isiqinisekiso se-MIC saseVietnam

ISetyhula 42/2016/TT-BTTTT ichaze ukuba iibhetri ezifakwe kwiifowuni eziphathwayo, iitafile kunye neencwadana zokubhalela azivumelekanga ukuba zithunyelwe eVietnam ngaphandle kokuba ziphantsi kwe-DoC certifctaion ukususela ngo-Oct.1,2016. I-DoC iya kuphinda ifuneke ukuba ibonelele xa ifaka isicelo sokuVunywa koHlobo lweemveliso zokuphela konyaka (iimfonomfono eziphathwayo, iitafile kunye neencwadana).

I-MIC ikhuphe iSetyhula entsha ye-04/2018/TT-BTTT ngoMeyi, i-2018 echaza ukuba akukho ngxelo ye-IEC 62133:2012 ekhutshwe yilabhoratri evunyiweyo yaphesheya yamkelwa ngoJulayi 1, 2018. Uvavanyo lwendawo luyimfuneko ngelixa ufaka isicelo sesatifikethi se-ADoC.

▍Umgangatho woVavanyo

QCVN101:2016/BTTT(bhekisa kwi-IEC 62133:2012)

▍PQIR

Urhulumente waseVietnam ukhuphe umyalelo omtsha onguNombolo 74/2018 / ND-CP ngoMeyi 15, 2018 ukuba uchaze ukuba iintlobo ezimbini zeemveliso ezingeniswe eVietnam zixhomekeke kwi-PQIR (Ukubhaliswa kokuHlolwa koMgangatho weMveliso) xa zithunyelwa eVietnam.

Ngokusekelwe kulo mthetho, i-Ofisi yoLwazi kunye noNxibelelwano (MIC) yaseVietnam ikhuphe uxwebhu olusemthethweni lwe-2305/BTTTT-CVT ngoJulayi 1, 2018, oluchaza ukuba iimveliso eziphantsi kolawulo lwayo (kubandakanywa neebhetri) kufuneka zifakwe kwi-PQIR xa zithunyelwa ngaphandle. ukuya eVietnam. I-SDoC iya kungeniswa ukuze igqibezele inkqubo yokukhutshwa kwempahla ekhoyo. Umhla osemthethweni wokungena ekusebenzeni kwalo mmiselo ngo-Agasti 10, 2018. I-PQIR isetyenziswa ekungeniseni enye eVietnam, oko kukuthi, rhoqo xa umthengisi engenisa iimpahla, uya kufaka isicelo se-PQIR (ukuhlolwa kwebhetshi) + SDoC.

Nangona kunjalo, kubarhwebi abangxamisekileyo ukuba bangenise iimpahla ngaphandle kwe-SDOC, i-VNTA iya kuqinisekisa okwethutyana i-PQIR kwaye iququzelele ukukhutshwa kwempahla. Kodwa abathumeli bangaphandle kufuneka bangenise i-SDoC kwi-VNTA ukuze igqibezele inkqubo yokukhutshwa kwempahla ngaphandle kwempahla ngaphakathi kwe-15 leentsuku zokusebenza emva kokukhutshwa kwempahla ephumayo. (I-VNTA ayisayi kuphinda ikhuphe i-ADOC yangaphambili esebenza kuphela kwi-Vietnam Local Manufacturers)

▍Kutheni i-MCM?

● Umxhasi woLwazi lwamva nje

● Umseki wegumbi lovavanyo lwebhetri yeQuacert

I-MCM ngoko iba yeyona arhente ikuphela kwayo yale lebhu e-Mainland China, eHong Kong, eMacau naseTaiwan.

● Inkonzo ye-Arhente yokuma enye

I-MCM, i-arhente efanelekileyo yokumisa enye, ibonelela ngovavanyo, isatifikethi kunye nenkonzo ye-arhente kubathengi.

Kule nyanga, i-IECEE ikhuphe izisombululo ezibini kwi-IEC 62133-2 malunga nokukhethwa komda ongaphezulu/osezantsi wokutshaja amaqondo obushushu eseli kunye nombane olinganiselweyo webhetri. Ezi zilandelayo zinkcukacha zezisombululo:Isisombululo sichaza ngokucacileyo: Kuvavanyo olululo, akukho kuphunyezwa komsebenzi we +/-5℃ okwamkelekileyo, kwaye ukutshaja kunokwenziwa kwiqondo lobushushu eliqhelekileyo lokutshaja elingaphezulu/elisezantsi xa utshaja indlela yeGatya 7.1.2 (ifuna ukutshaja kumaqondo aphezulu nasezantsi), nangona iSihlomelo A.4 somgangatho sichaza ukuba xa umlinganiselo wobushushu ongaphezulu/osezantsi ungekho. I-10 ° C / 45 ° C, iqondo lokushisa eliphezulu elilindelekileyo liya kunyuswa nge-5 ° C kunye nomlinganiselo ophantsi wokushisa kufuneka uncitshiswe nge-5 ° C. Ukongeza, iPhaneli ye-IEC SC21A (iKomiti yeTechnical ye-Alkaline kunye Iibhetri ezingena-Acidic) zijonge ukususa i+/-5℃ imfuneko kwiSihlomelo A.4 kwimeko ye-IEC 62133-2: 3.2017 / AMD2.Esinye isisombululo sijongana ngokuthe ngqo nomda we-IEC 62133-2 we-voltage ye-standard yeebhetri: akukho ngaphezu kwe-60Vdc. Nangona kungekho mda wombane ocacileyo unikiweyo kwi-IEC 62133-2, umgangatho wayo wereferensi, i-IEC 61960-3, ayibandakanyi iibhetri ezinombane oqhelekileyo olingana okanye ngaphezulu kwe-60Vdc ukusuka kububanzi bayo.
