Txhawm rau ua pov thawj tias cov khoom ua tau raws li cov qauv kev nyab xeeb thiab tau dhau qhov kev xeem UL, peb yuav muab UL daim ntawv lo rau ntawm cov khoom.
Cov txiaj ntsig ntawm UL Certification / UL Label
UL daim ntawv pov thawj feem ntau yog rau cov khoom pov thawj kev nyab xeeb thiab daim ntawv pov thawj kev nyab xeeb kev lag luam. Nws lub hom phiaj kawg yog coj cov khoom lag luam muaj kev nyab xeeb rau lub khw thiab pab ua kom tib neeg txoj kev noj qab haus huv thiab kev nyab xeeb.
Tau kawg, txais yuav UL daim ntawv pov thawj system yog yeem. Yog vim li cas thiaj li muaj coob tus neeg tseem thov?
Nov yog qee qhov laj thawj thiab cov txiaj ntsig ntawm kev luam ntawv UL daim ntawv pov thawj:
1. Muaj koob meej
UL daim ntawv pov thawj qhia tias lub tuam txhab cov khoom lag luam muaj kev tso cai ntau dua thiab muaj kev ntseeg siab ntawm kev nyab xeeb hauv kev siv. Tib lub sijhawm, qhov no kuj yog kev lag luam tag nrho kev lees paub ntawm lub tuam txhab cov khoom muaj kev nyab xeeb. Rau cov lag luam nrog UL ntawv pov thawj, cov neeg siv khoom thiab cov neeg yuav khoom yuav muaj kev ntseeg siab thiab kev ntseeg siab ntau dua.
2. Ua kom nrawm nrawm ntawm kev lag luam thoob ntiaj teb
Dhau UL daim ntawv pov thawj tuaj yeem txo lub sijhawm rau cov khoom lag luam nkag mus rau North American lag luam thiab tuaj yeem ua tiav xa tawm.. Nws yog qhov yooj yim rau lub tuam txhab hom kom nkag mus rau txoj kab nrawm nrawm hauv kev ua lag luam thoob ntiaj teb.
3. Cov qauv zoo
Ob tus neeg muag khoom thiab pab pawg neeg siv tau txhawj xeeb heev txog qhov zoo thiab kev nyab xeeb ntawm cov khoom. Tsis hais qhov twg lawv yuav khoom, lawv yuav tsom mus rau kev xaiv cov khoom nrog UL daim ntawv pov thawj. Qhov no tau dhau los ua tus qauv qub rau qee lub lag luam. Cov khoom uas tsis tau ntawv pov thawj UL feem ntau tsis lees txais kev yuav khoom.
4. keeb kwm ntev
Vim tias daim ntawv pov thawj UL muaj keeb kwm ntev thiab cov duab zoo heev, nws tau muab tob tob rau hauv lub siab ntawm cov neeg zoo tib yam. Txhawm rau ua kom cov khoom muag zoo dua hauv North American lag luam, ntau tus neeg nruab nrab yuav xav tau cov khoom kom muaj cov ntawv pov thawj.
5. Tej yam uas muaj feem cuam tshuam
Rau cov khoom tsis muaj ntawv pov thawj UL, qee lub tuam txhab tuav pov hwm yuav tsis pom zoo rau lawv. Ntxiv rau, Cov kev cai lij choj hauv zos tuaj yeem txwv cov lag luam los ntawm kev siv thiab muag cov khoom siv hluav taws xob yam tsis muaj ntawv pov thawj UL.
Hom ntawm UL Labels
UL daim ntawv pov thawj tuaj yeem muab faib ua ob theem rau ntau hom kev pabcuam UL: Daim ntawv pov thawj thiab lees paub daim ntawv pov thawj.
UL Listing yog siv rau daim ntawv pov thawj ntawm cov khoom tiav tiav. UL Recognition yog daim ntawv pov thawj kev nyab xeeb rau cov khoom siv thiab cov khoom siv. Hauv lwm lo lus, tsuas yog pom zoo cov khoom siv lossis cov khoom siv uas ua tau raws li qhov yuav tsum tau ua tuaj yeem sib sau ua ke thiab siv rau cov khoom kawg. Piv txwv xws li cov xov hlau, transformers, circuit boards, hloov, plugs, yas, hlau, lwm.
Ntxiv rau, peb tuaj yeem faib cov ntawv UL rau hauv peb hom hauv qab no:
1. UL npe
Cov khoom sib txawv uas yog cov kev pabcuam UL- npe feem ntau suav nrog ntau yam khoom siv hluav taws xob: xws li cov khoom siv hauv tsev, khoom siv kho mob, IT khoom, cov cuab yeej hluav taws xob, thiab lwm yam. Nws kuj tseem haum rau qee yam khoom, xws li keyboards, cov hlau, fuses, lwm.
2. UL Classified
Feem ntau, Cov khoom sib cais tsis yog cov khoom siv los ntawm cov neeg siv khoom, tab sis siv ntau dua los ntawm kev lag luam lossis kev lag luam. Yog li ntawd, cov kev xeem yuav tsum tau rau cov khoom xws li yuav nruj dua. Xws li kev lag luam tshuaj, khoom siv tsev, Cov khoom siv tiv thaiv hluav taws, lwm.
