Isethulo esifushane sesitifiketi se-UL

1. Mayelana ne-UL

I-UL imfushane yokuthi i-Underwriter Laboratories Inc. I-UL Safety Laboratory inegunya elikhulu e-United States futhi iyisikhungo esikhulu esizimele esizibandakanya nayo.ukuhlolwa kokuphephanokuhlonza emhlabeni.Kuyinhlangano ezimele, eyenza inzuzo eyenza ucwaningo lokuphepha komphakathi.Isitifiketi se-ULyisitifiketi esingaphoqelekile e-United States, ikakhulukazi ukuhlola kanye nesitifiketi sokusebenza kokuphepha komkhiqizo, futhi ububanzi baso besitifiketi asibandakanyi umkhiqizo.I-EMC(ukuhambisana kwe-electromagnetic) izici.

2. Inzuzo Yesitifiketi Se-UL

(1) 1.Imakethe yaseMelika yonke ibheka ukubaluleka okukhulu ekuphepheni komkhiqizo;abathengi nabathengi bazokhetha imikhiqizo enamamaki esitifiketi se-UL lapho bethenga imikhiqizo.

(2) I-UL inomlando ongaphezu kweminyaka eyi-100.Isithombe sokuphepha sigxile kakhulu kubathengi nakuhulumeni.Uma ungathengisi imikhiqizo ngokuqondile kubathengi, abaphakathi nabo bazodinga ukuthi imikhiqizo ibe namamaki esitifiketi se-UL ukwenza imikhiqizo yaziwe.

(3) Abathengi baseMelika namayunithi okuthenga banokuzethemba okwengeziwe emikhiqizweni yenkampani.

(4) Uhulumeni wobumbano, wesifunda, wesifunda, nomasipala wase-United States unengqikithi yezifunda zokuphatha ezingaphezu kuka-40,000, zonke eziqaphela uphawu lwesitifiketi se-UL.

3. I-Anbotek UL igunyaziwe

Njengamanje, i-Anbotek ithole ukugunyazwa kwe-WTDP kweI-UL60950-1futhiUL60065, okusho ukuthi konke ukubikezela nokuhlolwa kofakazi kungaqedwa e-anbotek, kunciphisa kakhulu umjikelezo wokunikeza izitifiketi.
