ANSI B93.64M : 83(R1989)

This Standard includes: the method of determining the pressure drop of hydraulic fluid power quick action couplings with male and female pipe thread end terminations, the method of determining the pressure drop of hydraulic fluid power quick action couplings with male and female SAE straight thread end terminations, pipe thread sizes from (1/8) one eighth inch to (2) two inches, straight thread sizes from 2 to 32 tube sizes, uniform methods of presenting test data numerically or graphically, only pipe threads and straight threads covered by recognized American Standards and is intended to provide, uniform laboratory procedures for measuring the pressure drop or hydraulic fluid power quick action couplings, standard means for reporting the above drop.
