▍ Chii chinonzi cTUVus & ETL CERTIFICATION?
OSHA (Occupational Safety and Health Administration), yakabatana neUS DOL (Department of Labor), inoda kuti zvigadzirwa zvese zvinofanirwa kushandiswa munzvimbo yebasa zviongororwe nekupihwa zvitupa neNRTL zvisati zvatengeswa pamusika. Miyero yekuyedza inoshanda inosanganisira American National Standards Institute (ANSI) zviyero; American Society for Testing Material (ASTM) zviyero, Underwriter Laboratory (UL) zviyero, uye fekitori mutual-recognition sangano zviyero.
▍OSHA, NRTL, cTUVus, ETL uye UL tsananguro yematemu nehukama
OSHA:Kupfupisa kweOccupational Safety uye Health Administration. Iyo mubatanidzwa weUS DOL (Dhipatimendi reVashandi).
NRTL:Kupfupisa kweNationally Recognized Testing Laboratory. Ndiyo inotarisira kubvumidzwa kwe lab. Kusvika parizvino, kune gumi nemasere echitatu-bato rekuyedza masangano akabvumidzwa neNRTL, kusanganisira TUV, ITS, MET zvichingodaro.
cTUVus:Certification chiratidzo cheTUVRh muNorth America.
ETL:Kupfupisa kweAmerican Electrical Testing Laboratory. Yakavambwa muna 1896 naAlbert Einstein, muvambi weAmerica.
UL:Nhoroondo ye Underwriter Laboratories, Inc.

▍ Neiko MCM?
● Tsigiro yakapfava kubva kuhunyanzvi uye tekinoroji:Seyapupu yekuyedza lab yeTUVRH neITS muNorth America Certification, MCM inokwanisa kuita marudzi ese ekuyedza uye nekupa sevhisi iri nani nekuchinjana tekinoroji chiso nechiso.
● Tsigiro yakaoma kubva kune tekinoroji:MCM inoshongedzerwa nemidziyo yese yekuyedza mabhatiri ehukuru-hukuru, diki-hukuru uye chaiyo mapurojekiti (kureva yemagetsi nharembozha, simba rekuchengetera, uye zvemagetsi zvigadzirwa zvedhijitari), inokwanisa kupa bhatiri rese rekuyedza uye masevhisi etifiketi muNorth America, inovhara zviyero. UL2580, UL1973, UL2271, UL1642, UL2054 zvichingodaro.
Mwedzi uno, UL yakagadziridzwaUL 1973nekuwedzera nickel-zinc bhatiri zvinodiwa uye kudzokorora mamwe maitiro ebvunzo emabhatiri nickel-cadmium nemabhatiri masisitimu. Chikonzero ndechekuti Appendikisi H haibatanidzi ese echargeable nickel makemikari. Appendikisi H, yekutanga Dzimwe Nzira dzeKuongorora Valve-inodzorwa kana Vented Lead-asidhi kana Nickel-cadmium Mabhatiri, yava Dzimwe Nzira dzeKuongorora Valve-inodzorwa kana Vented Lead- Asidhi kana Nickel-zinc Mabhatiri. Mamiriro ekuyedza akakodzera nickel-zinc bhatiri anowedzerwa kune nzira dzekuyedza dzekuwedzeredza, pfupi-circuit, overdischarge, tembiricha uye voltage kuramba.
Zvinoenderana neThe General Hofisi yeState Council maonero ekudzika shanduko yemagetsi nemagetsi indasitiri manejimendi system: lithium-ion mabhatiri uye mabhatiri mapaketi anoshandiswa mumagetsi nemagetsi zvigadzirwa, mabhangi emagetsi, uye magetsi adapta / charger inofananidzwa nevekufonera magumo zvigadzirwa, ichaverengerwa mukumanikidzwa chigadzirwa certification. Pazasi pane dzimwe nhau pamusoro pechitupa & kuyedzwa zviyero zvinosanganisirwa: Iyo GB/T 35590-2017 General Specification yePortable Power Supply yeIT Portable Digital Equipment yakagadziridzwa. Musangano wenhaurirano dzezviyero uchaitwa musi wa13 Gumiguru, 2022. Rumwe ruzivo ruchiri kuwanikwa kuti ndeupi chiyero chinofanira kutambirwa sechitupa uye chiyero chekuyedza chemabhatiri e-lithium ezvigadzirwa zvemagetsi. Parizvino, iyo yakanyanya kufanirwa chiyero chelithium mabhatiri emidziyo ndeye SJ/T 11757-2020.
