Tus qauv dynamic hauv tsev thiab txawv teb chaws,
UAS 1973,

▍ CTUVus & ETL CERTIFICATION yog dab tsi?

OSHA (Occupational Safety and Health Administration), koom nrog US DOL (Department of Labor), xav kom txhua yam khoom siv hauv chaw ua haujlwm yuav tsum tau kuaj thiab ntawv pov thawj los ntawm NRTL ua ntej muag hauv khw. Cov qauv xeem siv tau suav nrog American National Standards Institute (ANSI) cov qauv; American Society for Testing Material (ASTM) cov qauv, Underwriter Laboratory (UL) cov qauv, thiab lub koom haum kev sib nrig sib lees paub cov qauv.

▍OSHA, NRTL, cTUVus, ETL thiab UL cov ntsiab lus txhais thiab kev sib raug zoo

OSHA:Abbreviation of Occupational Safety and Health Administration. Nws yog kev koom tes ntawm US DOL (Department of Labor).

NRTL:Abbreviation of Nationally Recognized Testing Laboratory. Nws yog tus saib xyuas ntawm lab kev lees paub. Txog tam sim no, muaj 18 lub koom haum thib peb uas tau pom zoo los ntawm NRTL, suav nrog TUV, ITS, MET thiab lwm yam.

cTUV:Daim ntawv pov thawj ntawm TUVRh hauv North America.

ETL:Abbreviation of American Electrical Testing Laboratory. Nws tau tsim nyob rau xyoo 1896 los ntawm Albert Einstein, tus neeg tsim khoom Asmeskas.

UL:Cov ntawv luv ntawm Underwriter Laboratories Inc.

▍ Qhov txawv ntawm cTUVus, ETL & UL

▍ Vim li cas MCM?

● Kev txhawb nqa muag los ntawm kev tsim nyog thiab thev naus laus zis:Raws li lub chaw kuaj neeg ua pov thawj ntawm TUVRH thiab ITS hauv North American Certification, MCM muaj peev xwm ua tau txhua yam kev sim thiab muab kev pabcuam zoo dua los ntawm kev sib pauv tshuab ntsej muag.

● Kev txhawb nqa nyuaj los ntawm kev siv tshuab:MCM tau nruab nrog tag nrho cov khoom siv ntsuas rau cov roj teeb ntawm qhov loj-loj, me me thiab cov haujlwm ua tau zoo (xws li lub tsheb fais fab, lub zog cia, thiab cov khoom siv hluav taws xob digital), muaj peev xwm muab tag nrho cov roj teeb kuaj thiab ntawv pov thawj cov kev pabcuam hauv North America, npog cov qauv. UL2580, UL1973, UL2271, UL1642, UL2054 thiab lwm yam.

Lub hlis no, UL tau hloov khoUAS 1973los ntawm kev ntxiv cov nickel-zinc roj teeb uas yuav tsum tau ua thiab kho qee qhov kev ntsuas qhov tseem ceeb rau cov roj teeb nickel-cadmium thiab cov roj teeb. Qhov laj thawj yog tias Daim Ntawv Ntxiv H tsis suav nrog txhua cov tshuaj nickel rechargeable. Daim ntawv ntxiv H, Ameslikas Alternative Methods for Evaluating Valve-controlled or Vented Lead-acid or Nickel-cadmium Batteries, tam sim no Lwm Txoj Kev rau Kev Ntsuas Valve-tswj lossis Vented Lead- acid los yog Nickel-zinc roj teeb. Cov kev kuaj mob tsim nyog rau nickel-zinc roj teeb yog ntxiv rau cov kev sim ntawm overcharge, luv-circuit, overdischarge, kub thiab voltage kuj.
Raws li Lub Chaw Haujlwm Saib Xyuas Kev Ruaj Ntseg Hauv Lub Xeev txoj kev xav txog kev nkag siab tob txog kev hloov kho hluav taws xob thiab hluav taws xob kev lag luam kev lag luam: cov roj teeb lithium-ion thiab cov roj teeb uas siv hauv cov khoom siv hluav taws xob thiab hluav taws xob, lub tsev txhab nyiaj fais fab, thiab lub hwj chim adapter / charger matched nrog kev sib txuas lus kawg khoom, yuav suav nrog hauv daim ntawv pov thawj cov khoom uas yuav tsum tau ua. Hauv qab no yog qee cov xov xwm hais txog cov ntawv pov thawj & cov qauv ntsuas kev koom tes: The GB / T 35590-2017 General Specification for Portable Power Supply for IT Portable Digital Equipment tau raug kho dua. Kev sib tham txog cov qauv kev sib tham yuav muaj nyob rau lub Kaum Hlis 13, 2022. Cov ntaub ntawv ntxiv tseem yuav tau txais raws li tus qauv yuav tsum tau txais raws li daim ntawv pov thawj thiab cov qauv kuaj rau lithium roj teeb rau cov khoom siv hluav taws xob. Tam sim no, tus qauv tsim nyog tshaj plaws rau cov roj teeb lithium rau cov khoom siv yog SJ / T 11757-2020.
