Imikhiqizo yensimbi yase-US inamazinga amaningi, ikakhulukazi ezigabeni ezilandelayo:

I-ANSI- I-American National Standard

AISI- I-American Society of Iron and Steel Standards

I-ASTM- Inhlangano yaseMelika Yokuhlola Nezinto Zokusebenza

ASME- I-American Society of Mechanical Engineers

I-AMS-Ukucaciswa kwezinto ezibonakalayo ze-Aerospace (enye yezinto ezicaciswayo ezisetshenziswa kakhulu embonini yezokundiza yase-US, eyakhiwe yi-SAE)

I-API- Izindinganiso ze-American Petroleum Institute

AWS- I-American Welding Association Standard

SAE- I-American Society of Automotive Engineers Standards

I-MIL- Izindinganiso zezempi zase-US

Qq- Izindinganiso zikahulumeni wase-US

I-API- Izindinganiso ze-American Petroleum Institute

I-ANSI- I-American National Standard

ASME- I-American Society of Mechanical Engineers

I-ASTM- Inhlangano yaseMelika Yokuhlola Nezinto Zokusebenza

Lawa mazinga, wonke angaphansi kwamazinga ensimbi ase-US, afana ne-ASME kokuqukethwe okusetshenziswe amazinga asuka ku-ASTM, i-valve ku-API yereferensi evamile, nokufakwa kwepayipi lensimbi elithambile kusukela kuzinga le-ANSI.Umehluko ulele ekugxilweni okuhlukile kwemboni, ngakho ukwamukelwa kwamazinga ahlukene.I-API, ASTM, ASME amalungu e-ANSI.Amazinga e-American National Standards Institute, iningi elivela kumazinga ochwepheshe.Ngakolunye uhlangothi, izinhlangano zochwepheshe, izinhlangano, amaqembu angabuye asekelwe kumazinga akhona kazwelonke ukuthuthukisa amazinga athile omkhiqizo.Yiqiniso, abakwazi ukulandela indinganiso kazwelonke ukuthuthukisa eyabo izindinganiso association.Izindinganiso ze-ANSI zingezokuzithandela.I-United States ikholelwa ukuthi izindinganiso eziyisibopho zingakhawulela izinzuzo zokukhiqiza.Kodwa ngomthetho kanye neminyango kahulumeni ukuthuthukisa amazinga, ngokuvamile izinga okuyimpoqo.
