23/8/1994· My testing device complies with the current SAE J343 Impulse Test and SAE J1405 Flex-Impulse Test procedures for hydraulic hose asselies. These procedures establish a uniform method for comparative impulse testing of hydraulic hose asselies with and without flexing in order to determine the effect of flexing on the ultimate life of the hydraulic hose.
This hydraulic impulse tester is designed for testing parts of volumes up to 137 in 3 at pressures up to 7,500 PSIG utilizing MIL-PRF-83282 fluid. The project included: Software appliion programmed with our INERTIA test automation software , allowing for automated testing, manual control, calibration, and the ability for the end user to reconfigure the waveform or test profile for new
Impulse Testing of Hydraulic Hose Asselies. Septeer 7, 2018. The aim of any hydraulic hose coupling must be to grip the hose for the lifetime of the assely, never leak or weep and never blow off the hose. The ultimate test for an hydraulic assely is always “on the job”, as this proves whether the hose and couplings can meet the demands of
2/2/2010· The following article was contributed by Steven Hoff, Flextral''s VP of Engineering Services. Flextral hose and couplings are engineered to deliver top performance in the most demanding appliions. There are three primary factors that influence hydraulic hose life
Impulse testing is key to hose life as it cycles a hose at pressures up to 133% of the working pressure at 1 cycle per second. Hose assely robustness is vital to test performance. Our testing has shown non-genuine hoses had 10% to 20% lower performance than genuine Hitachi hoses.

Whereas a pressure gauge for a hydraulic appliion may only require 100,000 cycles. Other objectives may be more complied, with different usage scenarios, or even multiple loading parameters. In some cases, the manufacturer may dictate the pressure fatigue life of the product, but in today’s demanding market the more technically adept customers will be defining the requirements.
