▍Iyini i-cTUVus & ne-ETL CERTIFICATION?
I-OSHA (Occupational Safety and Health Administration), exhumene ne-US DOL (Umnyango Wezabasebenzi), ifuna ukuthi yonke imikhiqizo ezosetshenziswa emsebenzini kufanele ihlolwe futhi iqinisekiswe yi-NRTL ngaphambi kokuba idayiswe emakethe. Amazinga okuhlola asebenzayo ahlanganisa amazinga e-American National Standards Institute (ANSI); Amazinga e-American Society for Testing Material (ASTM), amazinga e-Underwriter Laboratory (UL), kanye namazinga enhlangano yokuqaphela mutual yefekthri.
▍OSHA, NRTL, cTUVus, ETL kanye nencazelo yamagama e-UL kanye nobudlelwano
OSHA:Isifinyezo Sokuphepha Kwasemsebenzini Nokuphathwa Kwezempilo. Kuyinhlangano ehlangene ye-US DOL (Umnyango Wezabasebenzi).
I-NRTL:Isifinyezo Selabhorethri Yokuhlola Eyaziwa Kuzwelonke. Iphethe ukugunyazwa kwelebhu. Kuze kube manje, kunezikhungo zokuhlola ezivela eceleni eziyi-18 ezigunyazwe yi-NRTL, okuhlanganisa i-TUV, ITS, MET njalonjalo.
cTUVus:Uphawu lwesitifiketi se-TUVRh eNyakatho Melika.
I-ETL:Isifinyezo se-American Electrical Testing Laboratory. Yasungulwa ngo-1896 ngu-Albert Einstein, umsunguli waseMelika.
UL:Ukulinganisa kwenkampani Underwriter Laboratories Inc.
▍Umehluko phakathi kwe-cTUVus, i-ETL ne-UL
| Into | UL | cTUVus | I-ETL |
| Kusetshenziswe okujwayelekile | Ngokufanayo | ||
| Isikhungo esifanelekile ukuthola irisidi yesitifiketi | I-NRTL (ilabhorethri egunyazwe kuzwelonke) | ||

▍Kungani i-MCM?
● Ukusekelwa Okuthambile okuvela kuziqu nobuchwepheshe:Njengelebhu yokuhlola yofakazi ye-TUVRH kanye ne-ITS kusitifiketi saseNyakatho Melika, i-MCM iyakwazi ukwenza zonke izinhlobo zokuhlola futhi inikeze isevisi engcono ngokushintshisana ngobuchwepheshe ubuso nobuso.
● Usekelo oluqinile oluvela kubuchwepheshe:I-MCM ifakwe zonke izinto zokuhlola amabhethri amaphrojekthi amakhulu, amancane futhi anembayo (okungukuthi imoto ephathwayo esebenza ngogesi, amandla okugcina, kanye nemikhiqizo yedijithali), ekwazi ukuhlinzeka ngezinsizakalo zokuhlola ibhethri kanye nezitifiketi eNyakatho Melika, ezihlanganisa izindinganiso. UL2580, UL1973, UL2271, UL1642, UL2054 njalonjalo.
Uhlolojikelele:
Isikuta sikagesi kanye ne-skateboard kufakwe ngaphansi kwe-UL 2271 ne-UL 2272 lapho kugunyazwe eNyakatho Melika. Nasi isingeniso, ebangeni abalihlanganisayo kanye nezimfuneko, zomehluko phakathi kwe-UL 2271 ne-UL 2272:UL 2272 iyatholakala kumadivayisi eselula omuntu siqu, njengalezi: izikuta zikagesi nezimoto ezibhalansi.
Kusukela kububanzi obujwayelekile, i-UL 2271 iyindinganiso yebhethri, futhi i-UL 2272 iyindinganiso yedivayisi. Uma wenza isitifiketi sedivayisi ye-UL 2272, ingabe ibhethri lidinga ukuqinisekiswa ku-UL 2271 kuqala?
Okokuqala, ake sazi ngezimfuneko ze-UL 2272 zamabhethri (amabhethri/amaseli e-lithium-ion kuphela acatshangelwa ngezansi):
Iseli: Amaseli e-lithium-ion kufanele ahlangabezane nezimfuneko ze-UL 2580 noma UL 2271;
Ibhethri: Uma ibhethri lihlangabezana nezidingo ze-UL 2271, lingakhishwa ekuhlolweni kokushajwa ngokweqile, i-short-circuit, ukukhipha ngokweqile kanye nokushaja okungenabhalansi.
Kungabonakala ukuthi uma ibhethri ye-lithium isetshenziswa entweni esebenza ku-UL 2272, akudingekile ukwenza isitifiketi se-UL 2271, kodwa iseli lidinga ukuhlangabezana nezidingo ze-UL 2580 noma i-UL 2271.
