Muyezo wamphamvu kunyumba ndi kunja,
UL 1973,
▍Kodi cTUVus & ETL CERTIFICATION ndi chiyani?
OSHA (Occupational Safety and Health Administration), yogwirizana ndi US DOL (Department of Labor), ikufuna kuti zinthu zonse zogwiritsidwa ntchito kuntchito ziyenera kuyesedwa ndi kutsimikiziridwa ndi NRTL zisanagulitsidwe pamsika. Miyezo yoyezetsa yogwiritsidwa ntchito ikuphatikiza miyezo ya American National Standards Institute (ANSI); Miyezo ya American Society for Testing Material (ASTM), Miyezo ya Underwriter Laboratory (UL), ndi miyezo ya bungwe lozindikiritsa fakitale.
▍OSHA, NRTL, cTUVus, ETL ndi UL matanthauzo ndi ubale
OSHA:Chidule cha Occupational Safety and Health Administration. Ndi mgwirizano wa US DOL (Department of Labor).
Mtengo wa NRTL:Chidule cha Nationally Recognized Testing Laboratory. Ndiwoyang'anira kuvomerezeka kwa labu. Mpaka pano, pali mabungwe oyesa 18 omwe avomerezedwa ndi NRTL, kuphatikiza TUV, ITS, MET ndi zina zotero.
cTUVus:Chizindikiro cha TUVRh ku North America.
Mtengo wa ETL:Chidule cha American Electrical Testing Laboratory. Idakhazikitsidwa mu 1896 ndi Albert Einstein, woyambitsa waku America.
UL:Malingaliro a magawo a Underwriter Laboratories Inc.
▍Kusiyana pakati pa cTUVus, ETL & UL

▍Chifukwa chiyani MCM?
● Thandizo Lofewa kuchokera ku qualification ndi teknoloji:Monga labu yoyesa mboni ya TUVRH ndi ITS ku North America Certification, MCM imatha kuyesa mitundu yonse ndikupereka ntchito zabwinoko posinthana ukadaulo maso ndi maso.
● Thandizo lolimba laukadaulo:MCM ili ndi zida zonse zoyezera mabatire akuluakulu, ang'onoang'ono komanso olondola (mwachitsanzo, galimoto yamagetsi yamagetsi, mphamvu zosungiramo zinthu, ndi zinthu zamagetsi zamagetsi), zomwe zimatha kupereka ntchito zonse zoyezera batire ndi ziphaso ku North America, zomwe zimakwaniritsa miyezo. UL2580, UL1973, UL2271, UL1642, UL2054 ndi zina zotero.
Mwezi uno, UL yasinthidwaUL 1973powonjezera zofunika za batri ya nickel-zinki ndikuwunikanso zoyeserera zamabatire a nickel-cadmium ndi makina a batri. Chifukwa chake n’chakuti Zowonjezera H sizimaphatikizapo mankhwala onse a faifi tambala. Zowonjezera H, zoyambilira Njira Zina Zowunikira Mabatire Oyendetsedwa ndi Valve kapena Otulutsa Lead-acid kapena Nickel-cadmium, tsopano ndi Njira Zina Zowunikira Mtsogoleri Wotsogola Woyendetsedwa ndi Vavu kapena Wotuluka- asidi kapena Nickel-zinc Mabatire. Miyezo yoyenera batire ya nickel-zinc imawonjezedwa ku njira zoyesera zochulukira, zofupikitsa, zotulutsa, kutentha ndi kukana kwamagetsi.
Malinga ndi malingaliro a The General Office of the State Council pakukula kwa kusintha kwa kayendetsedwe ka kayendetsedwe ka magetsi ndi zamagetsi: mabatire a lithiamu-ion ndi mapaketi a batri omwe amagwiritsidwa ntchito pazinthu zamagetsi ndi zamagetsi, mabanki amagetsi, ndi adaputala / charger yamagetsi yofananira ndi zinthu zomaliza zolumikizirana, zidzaphatikizidwa mu chiphaso chokakamiza chazinthu. Pansipa pali nkhani zina zokhuza certification & miyezo yoyesera zomwe zikukhudzidwa: Mafotokozedwe a GB/T 35590-2017 General Specification for Portable Power Supply for IT Portable Digital Equipment yasinthidwa. Msonkhano wokambitsirana za miyezo udzachitika pa Oct 13, 2022. Zambiri zidakalipobe zokhudza muyeso womwe uyenera kutsatiridwa ngati muyezo wotsimikizira ndi kuyesa mabatire a lifiyamu pazinthu zamagetsi zamagetsi. Pakadali pano, muyezo woyenera kwambiri wamabatire a lithiamu pazida zamagetsi ndi SJ/T 11757-2020.
