1. Isingeniso
Uma kukhulunywa ngezintambo zikagesi, ukuphepha nokusebenza yikona okuhamba phambili. Yingakho izifunda ezehlukene zinezinhlelo zazo zokunikeza izitifiketi zokuqinisekisa ukuthi amakhebuli ahlangabezana namazinga adingekayo.
Amasistimu wokunikeza izitifiketi amabili aziwa kakhuluI-UL (Underwriters Laboratories)futhiI-IEC (International Electrotechnical Commission).
- ULisetshenziswa kakhulu kui-America esenyakatho(USA naseCanada) futhi igxileukuhambisana nokuphepha.
- I-IECyin aizinga lomhlaba jikelele(evamile kuEYurophu, e-Asia, nakwezinye izimakethe) okuqinisekisa kokubiliukusebenza nokuphepha.
Uma u-aumkhiqizi, umphakeli, noma umthengi, ukwazi umehluko phakathi kwalezi zindinganiso ezimbilikubalulekile ekukhetheni izintambo ezifanele ezimakethe ezahlukene.
Ake singene phakathi komehluko obalulekileIzindinganiso ze-UL kanye ne-IECnokuthi ziwuthinta kanjani umklamo wekhebula, izitifiketi, nezinhlelo zokusebenza.
2. Umehluko Obalulekile Phakathi kwe-UL ne-IEC
| Isigaba | I-UL Standard (eNyakatho Melika) | I-IEC Standard (Global) |
|---|---|---|
| Ukuhlanganisa | Ikakhulukazi e-USA naseCanada | Isetshenziswa emhlabeni wonke (iYurophu, i-Asia, njll.) |
| Gxila | Ukuphepha komlilo, ukuqina, amandla emishini | Ukusebenza, ukuphepha, ukuvikelwa kwemvelo |
| Ukuhlolwa Kwelangabi | I-VW-1, FT1, FT2, FT4 (I-Strict flame retadancy) | I-IEC 60332-1, IEC 60332-3 (Izigaba zomlilo ezihlukene) |
| Izilinganiso zamandla kagesi | 300V, 600V, 1000V, njll. | 450/750V, 0.6/1kV, njll. |
| Izidingo Zempahla | Ikwazi ukumelana nokushisa, i-flame-retardant | Intuthu ephansi, izinketho ezingenayo i-halogen |
| Inqubo Yokuqinisekisa | Idinga ukuhlolwa kwelebhu ye-UL nokufakwa kuhlu | Idinga ukuthobela imininingwane ye-IEC kodwa iyahlukahluka ngezwe |
Okubalulekile Okuthathwayo:
✅I-UL igxile ekuphepheni nasekumelaneni nomlilo, ngenkathiI-IEC ilinganisa ukusebenza, ukusebenza kahle, kanye nokukhathazeka kwemvelo.
✅I-UL inokuhlolwa okuqinile kokuvutha,kodwaI-IEC isekela uhla olubanzi lwezintambo ezingenantuthu ephansi kanye ne-halogen.
✅Isitifiketi se-UL sidinga ukugunyazwa okuqondile, ngenkathiUkuthobela i-IEC kuyehluka ngokwemithetho yendawo.
3. Amamodeli Ekhebula Avamile e-UL kanye ne-IEC Emakethe Yomhlaba Wonke
Izinhlobo ezahlukene zezintambo zilandela amazinga e-UL noma e-IEC kuye ngezawoisicelo kanye nesidingo semakethe.
| Isicelo | I-UL Standard (eNyakatho Melika) | I-IEC Standard (Global) |
|---|---|---|
| Izintambo ze-Solar PV | I-UL4703 | I-IEC H1Z2Z2-K (EN 50618) |
| Amakhebula Amandla Wezimboni | UL 1283, UL 1581 | I-IEC 60502-1 |
| I-Building Wiring | I-UL 83 (THHN/THWN) | I-IEC 60227, IEC 60502-1 |
| Izintambo zokushaja ze-EV | UL 62, UL 2251 | I-IEC 62196, IEC 62893 |
| Izintambo Zokulawula Nesiginali | I-UL 2464 | I-IEC 61158 |
