▍ 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.

UL 2054 Ed.3 tau tshaj tawm thaum Lub Kaum Ib Hlis 17, 2021. Raws li tus tswv cuab ntawm UL tus qauv, MCM tau koom nrog kev tshuaj xyuas tus qauv, thiab tau muab cov lus qhia tsim nyog rau kev hloov kho uas tau txais yuav tom qab ntawd.
Cov kev hloov pauv uas tau ua rau cov qauv yog feem ntau koom nrog tsib yam, uas yog cov ntsiab lus raws li hauv qab no: Kev hloov kho lwm yam yog ua thoob plaws hauv Tus Qauv; Nqe 2–5, 6.1.2–6.1.4,
6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, Tshooj 23 lub npe, 24.1, Cov ntawv ntxiv A. Kev qhia meej ntawm cov cai rau cov ntawv nplaum; Tshooj 29, 30.1, 30.2.Ntxiv cov cai thiab cov txheej txheem ntawm Mark Durability Test .Made Limited Power Source Test ib qho kev xaiv; 7.1.Clarified sab nraud kuj nyob rau hauv qhov kev ntsuam xyuas nyob rau hauv 11.11.Qhov luv Circuit Court Test tau hais kom siv tooj liab hlau rau luv luv Circuit Court zoo thiab tsis zoo anodes nyob rau hauv seem 9.11 ntawm tus qauv qub, tam sim no tau hloov kho raws li siv 80 ± 20m
Ω sab nraud resistors.
Ntxiv ntawm ntu 6.3: Cov kev cai dav dav rau cov qauv ntawm cov xov hlau thiab cov terminals: Cov hlau yuav tsum tau insulated, thiab yuav tsum ua kom tau raws li cov cai ntawm UL 758 thaum txiav txim siab seb qhov kub thiab qhov hluav taws xob tau ntsib hauv pob roj teeb puas tau.Wiring hau thiab terminals yuav tsum yuav tsum tau mechanically reinforced, thiab hluav taws xob kev sib cuag yuav tsum tau muab, thiab yuav tsum tsis txhob muaj tensioning ntawm kev sib txuas thiab terminals. Cov hlau lead yuav tsum muaj kev nyab xeeb, thiab khaws cia kom deb ntawm cov npoo ntse thiab lwm qhov chaw uas yuav ua rau cov hlau insulator.
