Izinga eliguquguqukayo ekhaya naphesheya,
UL 1973,
▍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.
Kule nyanga, i-UL ichitshiyelweUL 1973ngokwengeza izidingo zebhethri le-nickel-zinc kanye nokubuyekeza amanani athile okuhlola amabhethri e-nickel-cadmium namasistimu ebhethri. Isizathu ukuthi iSithasiselo H asiwafaki wonke amakhemikhali e-nickel ashajwayo.Isithasiselo H, ekuqaleni Izindlela Ezihlukile Zokuhlola Amabhethri Alawulwa I-Valve noma Ama-Vented Lead-acid noma i-Nickel-cadmium, manje Sekuyizinye Izindlela Zokuhlola Umthofu Olawulwa I-Valve- i-asidi noma i-Nickel-zinc Amabhethri. Izimo zokuhlola ezifanele ibhethri le-nickel-zinc zengezwa ezindleleni zokuhlola zokushajwa ngokweqile, i-short-circuit, i-overdischarge, izinga lokushisa nokumelana ne-voltage.
Ngokombono we-The General Office of the State Council mayelana nokujulisa ukuguqulwa kohlelo lokuphatha imboni kagesi neye-elekthronikhi: amabhethri e-lithium-ion namaphakethe ebhethri asetshenziswa emikhiqizweni kagesi neye-elekthronikhi, amabhange kagesi, kanye ne-adaptha/ishaja yamandla ehambisana nemikhiqizo yokugcina yezokuxhumana, izofakwa esitifiketini somkhiqizo esiyimpoqo. Ngezansi kunezindaba ezithile mayelana nesitifiketi namazinga okuhlola ahilelekile: I-GB/T 35590-2017 Ukucaciswa Okujwayelekile Kokuhlinzekwa Kwamandla Aphathekayo Kwezisetshenziswa Zedijithali Eziphathwayo ze-IT kubuyekeziwe. Ingqungquthela yezingxoxo zamazinga izobanjwa ngo-Oct 13, 2022. Olunye ulwazi kusazotholwa mayelana nokuthi yiliphi izinga okufanele lamukelwe njengezinga lokugunyazwa nokuhlola lamabhethri e-lithium emikhiqizweni yezinto zikagesi. Njengamanje, izinga elifaneleka kakhulu lamabhethri e-lithium ezinto zikagesi yi-SJ/T 11757-2020.
