Nyaya yeUL 1642itsva yakadzokororwa vhezheni - Inorema kukanganisa kutsiva bvunzo yehomwe cell,
UL 1642,

▍Vietnam MIC Certification

Circular 42/2016/TT-BTTTT yakataura kuti mabhatiri akaiswa munharembozha, mahwendefa nemabhuku ekunyorera haabvumidzwe kuendeswa kunze kwenyika kuVietnam kunze kwekunge aiswa pasi peDoC certifctaion kubvira Oct.1,2016. DoC inozodikanwawo kupa kana uchinyorera Type Mvumo yezvigadzirwa zvekupedzisira (nharembozha, mahwendefa nemabhuku ekunyorera).

MIC yakaburitsa Circular 04/2018/TT-BTTT itsva muna Chivabvu, 2018 iyo inoti hapasisina IEC 62133:2012 mushumo wakabudiswa nerabhoritari yemhiri kwemakungwa yakatenderwa inogamuchirwa muna Chikunguru 1, 2018. Kuongororwa kwenzvimbo kunodiwa paunenge uchinyorera chitupa cheADoC.

▍PQIR

Hurumende yeVietnam yakapa chirevo chitsva No. 74/2018 / ND-CP musi wa15 Chivabvu, 2018 kuti vataure kuti marudzi maviri ezvigadzirwa zvinotengeswa kunze kwenyika kuVietnam zviri pasi pePQIR (Product Quality Inspection Registration) application painounzwa kuVietnam.

Zvichienderana nemutemo uyu, Ministry of Information and Communication (MIC) yekuVietnam yakapa gwaro repamutemo 2305/BTTTT-CVT musi waChikunguru 1, 2018, richitaura kuti zvigadzirwa zviri pasi payo (kusanganisira mabhatiri) zvinofanirwa kuiswa kuPQIR kana zvichitengeswa kunze kwenyika. kuVietnam. SDoC ichaendeswa kuti ipedze hurongwa hwekubvisa tsika. Zuva repamutemo rekupinda musimba remutemo uyu ndiAugust 10, 2018. PQIR inoshandiswa kune imwe chete inotengeswa kuVietnam, ndiko kuti, nguva dzose apo mutengesi anopinza zvinhu kunze kwenyika, achanyorera PQIR (batch inspection) + SDoC.

Nekudaro, kune vanotenga kunze kwenyika vari kukurumidza kupinza zvinhu kunze kweSDOC, VNTA ichaongorora PQIR kwenguva pfupi uye kufambisa kubvumidzwa kwetsika. Asi vanotenga kunze kwenyika vanofanirwa kuendesa SDoC kuVNTA kuti vapedze hurongwa hwese hwekubvisa tsika mukati memazuva gumi nemashanu ekushanda mushure mekubvumidzwa kwetsika. (VNTA haichabudisi yekare ADOC inongoshanda kuVietnam Local Manufacturers)

Imwe vhezheni itsva yeUL 1642 yakaburitswa. Imwe nzira kune inorema bvunzo bvunzo inowedzerwa kune masaru ehomwe. Izvo zvinodikanwa ndezvi: Kune pouch cell ine huwandu hwakakura kupfuura 300 mAh, kana ikapfuura iyo inorema bvunzo bvunzo isina kupasa, vanogona kuisirwa Section 14A round rod extrusion test.
Pouch cell haina nyaya yakaoma, iyo inowanzo tungamira mukutsemuka kwesero, kutsemuka kwepombi, marara achibhururuka kunze uye kumwe kukuvadzwa kwakakomba kunokonzerwa nekutadza muyedzo inorema, uye inoita kuti zvisakwanise kuona yemukati pfupi yedunhu inokonzerwa nekukanganisa dhizaini kana kukanganisa maitiro. . Iine round rod crush test, zvinokwanisika kukanganisa muchitokisi zvinogona kuonekwa pasina kukuvadza sero chimiro. Ongororo yakaitwa nemamiriro ezvinhu aya pachitariswa.  Isa muenzaniso panzvimbo yakati sandara. Isa simbi yakatenderera ine dhayamita ye25±1mm pamusoro pemuenzaniso. Mucheto wetsvimbo unofanirwa kuenderana nechepamusoro pesero, ine vertical axis perpendicular to the tab (FIG. 1). Kureba kwetsvimbo kunofanirwa kunge kuine 5mm yakafara pane yega yega yega yemuenzaniso wekuyedza. Kune maseru ane positive uye negative tabu kumativi akatarisana, rimwe nerimwe divi retabhu rinoda kuongororwa. Rutivi rumwe norumwe rwetebhu runofanira kuongororwa pamasampuli akasiyana.  Kuyerwa kwehukobvu (kushivirira ± 0.1mm) kwemasero kuchaitwa kusati kwaedzwa maererano neAppendix A yeIEC 61960-3 (Secondary masero nemabhatiri ane alkaline kana mamwe asiri- acidic electrolytes - Inotakurika sekondari lithium masero uye mabhatiri - Chikamu 3: Prismatic uye cylindrical lithium yechipiri masero nemabhatiri
