Yuav ua li cas hla ETL teev rau coj sawb?

Daim ntawv pov thawj ETL Sau npe yog muab los ntawm Nationally Recognized Testing Laboratory (NRTL) Intertek. Thaum ib yam khoom muaj ETL Cov Ntawv Teev Npe, nws qhia tias Intertek qhov kev ua tau zoo thiab cov qauv kev nyab xeeb tau ua tiav los ntawm kev sim. Cov khoom lag luam tau dhau los ua qhov kev sim ntau thiab kev ntsuam xyuas los lav kev ua raws li cov qauv kev lag luam thiab cov kev cai, raws li tau teev tseg los ntawm ETL Sau lub logo.
Cov lag luam thiab cov neeg siv khoom yuav xav tias muaj kev ruaj ntseg paub tias cov khoom lag luam tau dhau los ua kev sim siab los xyuas kom meej tias nws ua tau zoo thiab kev nyab xeeb thiab nws ua tau raws li tag nrho cov txheej txheem thaum nws dais ETL Sau lub logo. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ETL Listing thiab lwm cov npe NRTL, zoo li UL Listing, qhia tias ib yam khoom tau dhau los ntawm tib qho kev nyab xeeb thiab cov qauv zoo.

Cov qauv tsim thiab keeb kwm yav dhau los ntawm UL (Underwriters Laboratories) thiab ETL (Intertek) yog qhov tseem ceeb ntawm kev sib txawv. Nrog rau ntau tshaj li ib puas xyoo ntawm kev paub, UL yog ib tug stand-alone, non-profit lub koom haum paub zoo rau nws cov ntawv pov thawj thiab kev ntsuam xyuas cov khoom rau kev nyab xeeb. Txawm li cas los xij, Intertek, kev sim ntau lub teb chaws, kev tshuaj xyuas, thiab ntawv pov thawj lub koom haum uas muab ntau yam kev pabcuam tshaj li kev ntsuas kev nyab xeeb ntawm cov khoom, yog tus muab ETL cim.
UL thiab ETL muaj cov ntaub ntawv keeb kwm thiab cov qauv sib txawv, txawm hais tias lawv yog ob qho tib si Nationally Recognized Testing Laboratories (NRTLs) uas muab cov khoom sib piv cov khoom pov thawj kev nyab xeeb thiab kev pab cuam pov thawj. Lawv kuj tseem yuav siv cov txheej txheem sib txawv me ntsis thiab cov qauv rau cov khoom tshwj xeeb. Txawm li cas los xij, ib yam khoom tau raug tshuaj xyuas thiab pom tias ua tau raws li tag nrho cov qauv kev nyab xeeb thiab kev ua tau zoo yog tias nws dais UL lossis ETL Cov cim npe.

Koj yuav tsum xyuas kom meej tias koj cov khoom ua tau raws li ETL qhov kev ua tau zoo thiab kev nyab xeeb yuav tsum tau ua kom nws dhau ETL cov txheej txheem rau LED sawb teeb. Cov kev ua hauv qab no yuav pab tau koj kom tau txais koj cov LED sawb teeb teev nrog ETL:
Paub ETL Cov Qauv: Ua kom paub txog cov qauv ETL tshwj xeeb uas cuam tshuam rau LED sawb teeb pom kev zoo. Nws yog ib qho tseem ceeb kom nkag siab txog cov cai uas koj lub teeb ci LED yuav tsum ua kom tiav vim ETL muaj cov qauv sib txawv rau ntau yam khoom.
Cov Khoom Tsim thiab Kev Ntsuas: Txij thaum pib, xyuas kom koj lub teeb ci LED ua raws li tag nrho cov cai ETL. Qhov no tuaj yeem ua raws li cov qauv kev ua tau zoo, ua kom cov rwb thaiv tsev hluav taws xob raug teeb tsa kom raug, thiab siv cov khoom siv ETL pom zoo. Xyuas kom tseeb tias koj cov khoom txaus siab rau qhov tsim nyog kev ua tau zoo thiab cov qauv kev nyab xeeb los ntawm kev sim nws zoo.
Cov ntaub ntawv: Sau cov ntaub ntawv ntxaws ntxaws qhia txog seb koj lub teeb ci LED ua raws li ETL cov cai. Cov qauv tsim tshwj xeeb, cov txiaj ntsig kev xeem, thiab lwm cov ntaub ntawv tsim nyog yuav yog cov piv txwv ntawm qhov no.
Xa Koj Cov Teeb LED Sawb rau kev ntsuam xyuas: Xa koj cov teeb ci LED rau kev ntsuam xyuas rau ETL lossis qhov chaw kuaj pom los ntawm ETL. Txhawm rau kom paub tseeb tias koj cov khoom ua tau raws li qhov yuav tsum tau ua, ETL yuav ua qhov kev sim thiab ntsuas ntxiv.
Chaw Nyob Cov Lus Qhia: Thaum lub sij hawm kev ntsuam xyuas, yog ETL pom muaj teeb meem lossis thaj chaw tsis ua raws, kho cov teeb meem no thiab kho koj cov khoom raws li xav tau.
Daim ntawv pov thawj: Koj yuav tau txais daim ntawv pov thawj ETL thiab muaj koj cov khoom tsim raws li ETL tsim thaum koj lub teeb ci LED tau ua tiav tag nrho cov kev cai ETL.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov qauv tsim nyog yuav tsum tau txais daim ntawv pov thawj ETL rau LED sawb teeb tuaj yeem hloov pauv nyob ntawm tus qauv tsim, npaj siv, thiab lwm yam. Cov lus qhia tshwj xeeb ntxiv rau koj cov khoom tshwj xeeb tuaj yeem tau txais los ntawm kev koom tes nrog lub chaw kuaj pom zoo thiab tham nrog ETL ncaj qha.
