Dab tsi yog qhov sib txawv ntawm cov nyiaj tam sim no UL thiab IEC tam sim no?

1. Pib

Thaum nws los txog rau cov hluav taws xob cables, kev nyab xeeb thiab kev ua tau yog qhov tseem ceeb tshaj plaws. Tias yog vim li cas cov cheeb tsam sib txawv muaj lawv cov ntawv pov thawj cov ntawv pov thawj los xyuas kom meej tias cov khoom siv tau raws li cov qauv.

Ob ntawm cov txheej txheem zoo tshaj plaws yogUL (Underwriters Chaw soj ntsuam)thiabIEC (International ElectroteCnical Commission).

• ULyog siv nyob rau hauvNorth America(Tebchaws Asmeskas thiab Canada) thiab tsom mus rauKev Nyab Xeeb Kev Nyab Xeeb.
• Iecyog aNtiaj Teb Tus Qauv(ntau yam hauvTeb chaws Europe, Asia, thiab lwm yam kev lag luam) uas ua kom muaj ob qho tib siKev ua tau zoo thiab kev nyab xeeb.

Yog koj yog aChaw tsim tshuaj paus, chaw muag khoom, lossis tus yuav khoom, paub txog qhov sib txawv ntawm ob qho qauv no yogQhov tseem ceeb rau xaiv cov cables zoo rau kev sib txawv.

Wb dhia rau hauv qhov sib txawv tseem ceeb ntawmUL thiab IEEC Cov QauvThiab lawv yuav cuam tshuam cable tsim, ntawv pov thawj, thiab kev siv.

2. Qhov sib txawv tseem ceeb ntawm ul thiab iec

Tseem ceeb takaways:

✅UL yog tsom rau kev nyab xeeb thiab hluav taws kub tiv, thaumIEC sib npaug kev ua tau zoo, ua tau zoo, thiab kev txhawj xeeb ib puag ncig.
✅UL muaj cov kev ntsuas stricter, tab sisIEC txhawb nqa ntau yam ntawm cov pa hluav taws thiab halogen-dawb.
✅UL daim ntawv pov thawj yuav tsum tau kev pom zoo ncaj qha, thaumIec ua raws li kev sib txawv los ntawm cov cai hauv zos.

3. Cov qauv UL thiab IEC Cable qauv hauv kev ua lag luam thoob ntiaj teb

Ntau hom cable ntawm cov cable ua raws li cov qauv IEC raws lawvDaim ntawv thov thiab kev ua lag luam xav tau.
