North American cTUVus & ETL,
cTUVus & ETL,
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: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.

● 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.
I-Occupational Safety and Health Administration (OSHA) ngaphansi koMnyango Wezabasebenzi wase-US idinga ukuthi imikhiqizo esetshenziswa endaweni yokusebenza ihlolwe futhi iqinisekiswe ilabhorethri eyaziwa kuzwelonke ngaphambi kokuthi ithengiswe emakethe. Amazinga okuhlola asetshenziswayo ahlanganisa i-American National Standards Institute (ANSI); I-American Society for Testing and Materials (ASTM); I-Underwriters Laboratory (UL); kanye nezinga lenhlangano yocwaningo lokuqashelwa okufanayo kwamafekthri.
I-NRTL imfishane yokuthi Ilabhorethri Yokuhlola Eyaziwa Kuzwelonke. Isamba sezikhungo eziyi-18 zokunikeza izitifiketi nokuhlola zezinkampani zangaphandle zibonwe yi-NRTL, okuhlanganisa i-TUV, ITS kanye ne-MET kuze kube manje.
I-cETlus Mark: I-North America Certification Mark of Electrical Testing Labs of United States.
I-cTUVus Mark: I-North America Certification Mark ye-TUV Rheinland.
I-MCM isebenza njengelabhorethri yofakazi ye-TUV RH kanye ne-ITS ohlelweni lokunikeza izitifiketi lwaseNyakatho Melika. Zonke izivivinyo zingenziwa elabhorethri ye-MCM, ihlinzeka amakhasimende ngezinsizakalo zokuxhumana ezingcono zobuso nobuso.
