Ha ho tluoa tabeng ea lithapo tsa motlakase, polokeho le ts'ebetso ke tsona tse tlang pele. Ke ka lebaka leo libaka tse fapaneng li nang le litsamaiso tsa tsona tsa setifikeiti ho netefatsa hore likhoele li fihlela maemo a hlokahalang.
Litsamaiso tse peli tse tsebahalang haholo tsa setifikeiti keUL (Underwriters Laboratories)leIEC (Khomishene ea Machabeng ea Motlakase).

2. Phapang ea Sehloho lipakeng tsa UL le IEC
| Sehlopha | UL Standard (Amerika Leboya) | IEC Standard (Lefatšeng) |
|---|---|---|
| Kakaretso | Haholo-holo USA & Canada | E sebelisoa lefatšeng ka bophara (Europe, Asia, joalo-joalo) |
| Tsepamisa maikutlo | Tšireletseho ea mollo, ho tšoarella, matla a mochine | Tshebetso, polokeho, tshireletso ya tikoloho |
| Liteko tsa Lelakabe | VW-1, FT1, FT2, FT4 (Tlhahiso e thata ea lelakabe) | IEC 60332-1, IEC 60332-3 (Likarolo tse fapaneng tsa mollo) |
| Litekanyetso tsa Voltage | 300V, 600V, 1000V, joalo-joalo. | 450/750V, 0.6/1kV, joalo-joalo. |
| Litlhoko tsa Lintho | E thibela mocheso, e thibela lelakabe | Mosi o fokolang, likhetho tse se nang halogen |
| Mokhoa oa Setifikeiti | E hloka tlhahlobo ea lab ea UL le lethathamo | E hloka ho tsamaellana le lintlha tsa IEC empa e fapana ho ea ka linaha |
Lintlha tsa bohlokoa:
✅UL e shebane le polokeho le ho hanyetsa mollo, haIEC e leka-lekanya ts'ebetso, katleho, le mathata a tikoloho.
✅UL e na le liteko tse thata tsa ho cha, empaIEC e ts'ehetsa mehala e mengata e fapaneng ea mosi o tlase le e se nang halogen.
✅Setifikeiti sa UL se hloka tumello e tobileng, haHo latela melao ea IEC ho fapana ho ea ka melao ea lehae.
