Kana zvasvika kumagetsi emagetsi, kuchengetedzwa uye kuita ndizvo zvinhu zvekutanga zvekutanga. Ndokusaka matunhu akasiyana aine masangano avo ezvematongerwo ekuti ave nechokwadi chekuti tambo dzisangane nezvinodiwa zvinodiwa.
Maviri ezvakanaka-zvinozivikanwa zvitupa masisitimu ariUl (underwriters laboratories)uyeIEC (International Electrotechnicial Commission).
- ULinonyanya kushandiswa mukatiNorth America(USA neCanada) uye inotarisa paneKuchengetedza Kuteedzera.
- IECaGlobal Standard(zvakajairika mukatiEurope, Asia, uye mamwe misika) iyo inovimbisa zvese zviri zviviriKuita uye kuchengeteka.
Kana iwe uriMugadziri, mutengesi, kana mutengi, kuziva misiyano pakati peaya maviri zviyeroyakakosha pakusarudza tambo dzakaringana dzemisika dzakasiyana.
Ngatisvike mumusanganiswa wakakosha pakatiUl uye IEC zviyerouye kuti vanokanganisa sei tambo dhizaini, chitupa, uye zvinoshandiswa.
2. Misiyano yakakosha pakati peUL uye IEC
| Chikamu | UL standard (North America) | IEC Standard (Global) |
|---|---|---|
| Kufukidzwa | Kunyanya USA & Canada | Inoshandiswa pasi rese (Europe, Asia, nezvimwewo) |
| Tarisa | Kuchengetedzwa kwemoto, kusimba, simba rekuita | Performance, kuchengeteka, kuchengetedzwa kwezvakatipoteredza |
| Murazvo wekuongororwa | Vw-1, ft1, ft2, ft4 (yakasimba yemurazvo wekudzoreredza restard) | IEC 60332-1, IEC 60332-3 (dzakasiyana moto kudzika) |
| Voltage ratings | 300, 600v, 1000V, nezvimwe. | 450 / 750V, 0.6 / 1KV, nezvimwe |
| Zvinodiwa zvezvinhu | Kupisa-kupesana, murazvo-kudzoreredza | Svutugadzike-utsi, halogen-free sarudzo |
| Maitiro Ekutsigira | Inoda UL lab kuongororwa uye kunyora | Inoda kuteerana neIEC specs asi inosiyana nenyika |
Key Dealoways:
✅Ul inotarisisa pane chengetedzo uye kudzivisa moto, nepoIEC zviyero zvekuita, kushanda zvakanaka, uye zvakatipoteredza zvinetso.
✅UL ine inopindirana inopisa bvunzo, asiIEC inotsigira yakawedzera huwandu hweshuwa-utsi uye halogen-emahara tambo.
✅Ul certification inoda kutenderwa zvakananga, nepoIEC kutevedzera inosiyana nemirairo yemuno.

Mhando dzakasiyana dzemabhokisi anotevera Ul kana IEC zviyero zvinoenderana nekwavoChikumbiro uye Musika Kuda.
