i-America esenyakathoI-CTIA,
I-CTIA,
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-CTIAimele i-Cellular Telecommunications and Internet Association, inhlangano ezimele engenzi nzuzo e-United States. I-CTIA ihlinzeka ngokuhlolwa komkhiqizo okungachemile, okuzimele kanye nendawo eyodwa kanye nesitifiketi semboni engenazintambo. Ngaphansi kwalolu hlelo lwesitifiketi, yonke imikhiqizo engenantambo yabathengi kufanele iphumelele ukuhlolwa kokuvumelana okuhambisanayo futhi ihlangabezane nezidingo zamazinga afanele ngaphambi kokuthi ithengiswe emakethe yezokuxhumana yaseNyakatho Melika.Isidingo Sokugunyazwa Kwesistimu Yebhethri Ukuthobelana ku-IEEE1725 sisebenza kuseli eyodwa kanye amabhethri amaseli amaningi ahambisana.Isidingo Sokugunyazwa Kwesitifiketi Sohlelo Lwebhethri Ukuhambisana ne-IEEE1625 kusebenza kumabhethri amaningi amaseli enokuxhumana okuyinhloko ochungechungeni noma ngokuhambisana.Isaziso: kokubili ibhethri leselula kanye nebhethri yekhompyutha kufanele ikhethe izinga lokuqinisekisa ngokusho okungenhla, esikhundleni se-IEEE1725 yomakhalekhukhwini kanye ne-IEEE1625 yekhompyutha.I-MCM ilabhorethri egunyazwe yi-CTIA.I-MCM inganikeza isethi egcwele yesevisi yohlobo lomphathi okuhlanganisa ukuthumela isicelo, ukuhlola, ukuhlola nokulayisha idatha, njll.
