1. Mawu Oyamba
Pankhani ya zingwe zamagetsi, chitetezo ndi magwiridwe antchito ndizofunikira kwambiri. Ichi ndichifukwa chake madera osiyanasiyana ali ndi machitidwe awoawo otsimikizira kuti zingwe zimakwaniritsa zofunikira.
Awiri mwa machitidwe odziwika bwino a certification ndiUL (Underwriters Laboratories)ndiIEC (International Electrotechnical Commission).
- ULamagwiritsidwa ntchito makamaka mukumpoto kwa Amerika(USA ndi Canada) ndipo imayang'ana kwambirikutsata chitetezo.
- IECndi amulingo wapadziko lonse lapansi(wamba muEurope, Asia, ndi misika ina) zomwe zimatsimikizira zonse ziwirintchito ndi chitetezo.
Ngati ndinu awopanga, wogulitsa, kapena wogula, kudziwa kusiyana pakati pa miyezo iwiriyi ndizofunika posankha zingwe zoyenera misika yosiyanasiyana.
Tiyeni tilowe muzosiyana zazikuluzikuluMiyezo ya UL ndi IECndi momwe zimakhudzira mapangidwe a chingwe, certification, ndi ntchito.
2. Kusiyana Kwakukulu Pakati pa UL ndi IEC
| Gulu | UL Standard (North America) | IEC Standard (Global) |
|---|---|---|
| Kufotokozera | Makamaka USA & Canada | Amagwiritsidwa ntchito padziko lonse lapansi (Europe, Asia, etc.) |
| Kuyikira Kwambiri | Moto chitetezo, durability, makina mphamvu | Kuchita, chitetezo, chitetezo cha chilengedwe |
| Mayeso a Flame | VW-1, FT1, FT2, FT4 (Kuchedwa kwamoto kolimba) | IEC 60332-1, IEC 60332-3 (Magulu osiyanasiyana amoto) |
| Mavoti a Voltage | 300V, 600V, 1000V, etc. | 450/750V, 0.6/1kV, etc. |
| Zofunika Zakuthupi | Zosagwirizana ndi kutentha, zoletsa moto | Zosankha zopanda utsi, zopanda halogen |
| Njira Yotsimikizira | Imafunikira kuyezetsa kwa labu ya UL ndi mindandanda | Imafunika kutsata ma IEC koma imasiyana malinga ndi mayiko |
Zofunika Kwambiri:
✅UL imayang'ana kwambiri chitetezo ndi kukana moto, pameneIEC imayang'anira magwiridwe antchito, magwiridwe antchito, komanso zovuta zachilengedwe.
✅UL ili ndi mayeso okhwima oyaka moto,komaIEC imathandizira mitundu ingapo ya zingwe zotsika utsi komanso zingwe zopanda halogen.
✅Chitsimikizo cha UL chimafuna chivomerezo chachindunji, pameneKutsatira kwa IEC kumasiyana malinga ndi malamulo akumaloko.
3. Common UL ndi IEC Cable Models mu Global Market
Mitundu yosiyanasiyana ya zingwe imatsata milingo ya UL kapena IEC kutengera zomwe zilintchito ndi kufunikira kwa msika.
| Kugwiritsa ntchito | UL Standard (North America) | IEC Standard (Global) |

| Zingwe za Solar PV | Mtengo wa UL4703 | IEC H1Z2Z2-K (EN 50618) |
| Zida Zamagetsi Zamagetsi | UL 1283, UL 1581 | IEC 60502-1 |
