Pressure Decay Test with assembly working pressure of 7,500 psi: a worked example

This scenario runs the pressure decay test calculation on the strong side: assembly working pressure of 7,500 psi, with every other input held at its documented default. Use it when setting up a pressure decay leak test procedure for hose or tubing assemblies, or reviewing test parameters against the product working pressure.

The inputs for this scenario

  • Assembly working pressure: 7,500 psi (raised for this scenario; the documented default is 3,000)
  • Test pressure multiplier: 1.5 x (unchanged)
  • Test hold time: 0.08 hr (unchanged)

Working through the calculation

  • Applying the documented formula (Pressure decay test pressure = working pressure x test pressure multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 11,250 psi for total load, the number this scenario is built around.
  • At this operating point the engine returns 135,542 psi / hr for hourly equivalent.
  • At this operating point the engine returns 7,500 psi for input load.
  • At this operating point the engine returns 1.5 x for test pressure multiplier.

How this compares with the baseline

  • Against the tool's baseline example, where assembly working pressure sits at 3,000 psi and the headline result is 4,500 psi, this scenario comes in 150% above the baseline at 11,250 psi.
  • Use it when writing a proof-test spec, qualifying a new crimp die, or auditing whether your test stand pressure matches the assembly's rating. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
