Maodzanyemba America: Zvitsva zvekuchengetedza zviyero zvebhatani / mari yebhatiri zvigadzirwa
North America: Mitsva yekuchengetedza zviyero zvebhatani/mari bhatirizvigadzirwa,
bhatani/mari bhatiri,
▍ Chii chinonzi cTUVus & ETL CERTIFICATION?
OSHA (Occupational Safety and Health Administration), yakabatana neUS DOL (Department of Labor), inoda kuti zvigadzirwa zvese zvinofanirwa kushandiswa munzvimbo yebasa zviongororwe nekupihwa zvitupa neNRTL zvisati zvatengeswa pamusika. Miyero yekuyedza inoshanda inosanganisira American National Standards Institute (ANSI) zviyero; American Society for Testing Material (ASTM) zviyero, Underwriter Laboratory (UL) zviyero, uye fekitori mutual-recognition sangano zviyero.
▍OSHA, NRTL, cTUVus, ETL uye UL tsananguro yematemu nehukama
OSHA:Kupfupisa kweOccupational Safety uye Health Administration. Iyo mubatanidzwa weUS DOL (Dhipatimendi reVashandi).
NRTL:Kupfupisa kweNationally Recognized Testing Laboratory. Ndiyo inotarisira kubvumidzwa kwe lab. Kusvika parizvino, kune gumi nemasere echitatu-bato rekuyedza masangano akabvumidzwa neNRTL, kusanganisira TUV, ITS, MET zvichingodaro.
cTUVus:Certification chiratidzo cheTUVRh muNorth America.
ETL:Kupfupisa kweAmerican Electrical Testing Laboratory. Yakavambwa muna 1896 naAlbert Einstein, muvambi weAmerica.
UL:Nhoroondo ye Underwriter Laboratories, Inc.

▍ Neiko MCM?
● Tsigiro yakapfava kubva kuhunyanzvi uye tekinoroji:Seyapupu yekuyedza lab yeTUVRH neITS muNorth America Certification, MCM inokwanisa kuita marudzi ese ekuyedza uye nekupa sevhisi iri nani nekuchinjana tekinoroji chiso nechiso.
● Tsigiro yakaoma kubva kune tekinoroji:MCM inoshongedzerwa nemidziyo yese yekuyedza mabhatiri ehukuru-hukuru, diki-hukuru uye chaiyo mapurojekiti (kureva yemagetsi nharembozha, simba rekuchengetera, uye zvemagetsi zvigadzirwa zvedhijitari), inokwanisa kupa bhatiri rese rekuyedza uye masevhisi etifiketi muNorth America, inovhara zviyero. UL2580, UL1973, UL2271, UL1642, UL2054 zvichingodaro.
United States ichangobva kuburitsa sarudzo mbiri dzekupedzisira muFederal Register
