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

▍ Chii chinonzi WERCSmart REGISTRATION?

WERCSmart ndiyo chidimbu cheWorld Environmental Regulatory Compliance Standard.

WERCSmart ikambani yekunyoresa zvigadzirwa dhatabhesi yakagadziriswa nekambani yekuUS inonzi The Wercs. Inotarisira kupa chikuva chekutarisa chekuchengetedza zvigadzirwa zvezvitoro zvikuru muUS neCanada, uye kuita kuti kutenga zvigadzirwa kuve nyore. Mukuita kwekutengesa, kutakura, kuchengetedza uye kurasa zvigadzirwa pakati pevatengesi uye vanogamuchira vakanyoreswa, zvigadzirwa zvichasangana nekuwedzera kuomarara kubva kumubatanidzwa, nyika kana mutemo wemuno. Kazhinji, iyo Safety Data Sheets (SDSs) inopihwa pamwe chete nezvigadzirwa hazvivharise data rakakwana iro ruzivo runoratidza kutevedzera mitemo nemirau. Nepo WERCSmart ichishandura data yechigadzirwa kuti ienderane nemitemo nemirau.

▍Chikamu chezvigadzirwa zvekunyoresa

Vatengesi vanosarudza zvimiro zvekunyoresa kune umwe neumwe mutengesi. Mapato anotevera achanyoreswa kuti aonekwe. Nekudaro, iyo rondedzero iri pazasi haina kukwana, saka simbisa pane kunyoresa zvinodiwa nevatengi vako inokurudzirwa.

◆ Yese Chemical Iine Chigadzirwa

◆OTC Product uye Nutritional Supplements

◆Personal Care Products

◆Battery-Driven Products

◆Zvigadzirwa zvine Circuit Boards kana Electronics

◆Marabhu eChiedza

◆Mafuta ekubikisa

◆Chikafu chinopihwa neAerosol kana Bag-On-Valve

▍Nei MCM?

● Rutsigiro rwevashandi vehunyanzvi: MCM yakashongedzerwa nechikwata chehunyanzvi chinodzidza mitemo nemirairo yeSDS kwenguva refu. Ivo vane ruzivo rwakadzama rwekuchinja kwemitemo nemirau uye vakapa mvumo yeSDS sevhisi kwemakore gumi.

● Yakavharwa-loop mhando sevhisi: MCM ine vashandi vane hunyanzvi vanotaurirana nevanoongorora kubva kuWERCSmart, vachiva nechokwadi chekunyoresa uye kusimbiswa. Parizvino, MCM yakapa WERCSmart kunyoresa sevhisi kune vanopfuura mazana maviri vatengi.

Imwe vhezheni itsva yeUL 1642 yakaburitswa. Imwe nzira kune inorema bvunzo bvunzo inowedzerwa kune masaru ehomwe. Zvinodiwa chaizvo ndezvi: For pouch cell ine simba inopfuura 300 mAh, kana ikapasa inorema bvunzo bvunzo haina kupfuurwa, vanogona kuitiswa Section 14A round rod extrusion test.Pouch cell haina nyaya yakaoma, iyo inowanzotungamira kuputika kwesero, kutsemuka kwepombi, marara ari kubhururuka kunze uye kumwe kukuvadzwa kwakakomba kunokonzerwa nekutadza muyedzo inorema, uye zvinoita kuti zvisakwanise kuona mukati mepfupi wedunhu kunokonzerwa nekukanganisa kwedhizaini kana kukanganisa maitiro. Iine round rod crush test, zvinokwanisika kukanganisa muchitokisi zvinogona kuonekwa pasina kukuvadza sero chimiro. Ongororo yakaitwa nemamiriro ezvinhu aya tichitariswa.  Sample inochajiswa zvizere sezvakakurudzirwa nemugadziri Isa sampuli 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 yechipiri lithium masero nemabhatiri - Chikamu 3: Prismatic uye cylindrical lithium yechipiri masero uye mabhatiri)  Ipapo kusvina kudzvanywa kunoshandiswa pane yakatenderedza tsvimbo uye kutama munzira yakatwasuka kunonyorwa (FIG. 2). Iyo inofamba yekumhanya kwendiro yekutsikirira haifanire kunge yakakura kupfuura 0.1mm / s. Kana deformation yesero yasvika 13 ± 1% yehukobvu hwesero, kana kudzvanywa kunosvika kune simba rinoratidzwa muTable 1 (akasiyana maseru ukobvu anoenderana neakasiyana masimba masimba), misa ndiro yekusimuka uye uibate kwe30s. Muedzo unopera.
