Lub Koom Haum Thoob Ntiaj Teb Electrotechnical Commission (IEC) tau tsim tsa xyoo 1906 thiab muaj keeb kwm 109 xyoo txog rau xyoo 2015. Nws yog lub koom haum thoob ntiaj teb electrotechnical standardization thaum ntxov tshaj plaws hauv ntiaj teb, uas yog lub luag haujlwm rau kev ua tus qauv thoob ntiaj teb hauv kev tsim hluav taws xob thiab kev tsim hluav taws xob. Lub hauv paus ntawm International Electrotechnical Commission tau nyob hauv London, tab sis tau tsiv mus rau nws lub hauv paus tam sim no hauv Geneva xyoo 1948. Ntawm 6 lub rooj sib tham thoob ntiaj teb electrotechnical uas tau muaj txij li xyoo 1887 txog 1900, cov kws tshaj lij koom nrog tau pom zoo tias nws yog qhov tsim nyog los tsim kom muaj lub koom haum thoob ntiaj teb electrotechnical standardization mus tas li los daws cov teeb meem ntawm kev nyab xeeb hluav taws xob thiab kev ua tus qauv khoom hluav taws xob. Xyoo 1904, Lub Rooj Sib Tham Thoob Ntiaj Teb Electrotechnical uas tau muaj nyob hauv St. Louis, Tebchaws Meskas, tau pom zoo rau kev tsim kom muaj lub koom haum mus tas li. Thaum Lub Rau Hli 1906, cov neeg sawv cev ntawm 13 lub tebchaws tau ntsib hauv London, tau sau cov cai IEC thiab cov cai ntawm cov txheej txheem, thiab tau tsim tsa International Electrotechnical Commission. Xyoo 1947 nws tau koom nrog rau hauv Lub Koom Haum Thoob Ntiaj Teb rau Kev Txheem (ISO) ua ib lub chaw faib hluav taws xob, thiab xyoo 1976 nws tau raug cais tawm ntawm ISO. Lub hom phiaj yog txhawb kev koom tes thoob ntiaj teb ntawm txhua yam teeb meem ntsig txog kev cai lij choj hluav taws xob hauv cov teb ntawm hluav taws xob, hluav taws xob thiab cov thev naus laus zis cuam tshuam, xws li kev ntsuam xyuas kev ua raws li cov qauv. Lub hom phiaj ntawm pawg neeg yog: kom ua tau raws li qhov xav tau ntawm kev lag luam thoob ntiaj teb; kom ntseeg tau tias qhov tseem ceeb thiab siv ntau tshaj plaws ntawm nws cov qauv thiab cov phiaj xwm ntsuam xyuas kev ua raws li thoob ntiaj teb; los ntsuam xyuas thiab txhim kho qhov zoo ntawm cov khoom thiab cov kev pabcuam uas nws cov qauv them; los muab rau kev siv dav dav ntawm cov txheej txheem nyuaj Tsim cov xwm txheej; nce kev ua haujlwm ntawm cov txheej txheem kev lag luam; txhim kho kev noj qab haus huv thiab kev nyab xeeb ntawm tib neeg; tiv thaiv ib puag ncig.
NEMA motors yog tus qauv Asmeskas.
NEMA tau tsim muaj xyoo 1926. Lub koom haum kev lag luam tsim khoom siv hluav taws xob thawj zaug hauv Tebchaws Meskas tau tsim muaj xyoo 1905, hu ua Electronic Manufacturers Alliance (Electrical Manufacturers Alliance: EMA), thiab tsis ntev tom qab ntawd tau hloov nws lub npe mus rau Electrical Manufacturers Club (Electrical Manufacturers Club: EMC), 1908 American motor manufacturers Lub Koom Haum American Association of Electric Motor Manufacturers: AAEMM tau tsim muaj, thiab xyoo 1919 nws tau hloov lub npe mus ua Electric Power Club (Electric Power Club: EPC). Peb lub koom haum tau koom ua ke los tsim Electrical Manufacturers Council (EMC).
