Leak Test Workload Calculator at 21% retest and handling allowance: a worked example

This scenario runs the leak test workload calculator calculation on the strong side: 21% retest and handling allowance, with every other input held at its documented default. a test engineer needs to size leak-test capacity for a sealed-system production schedule

The inputs for this scenario

  • Units or assemblies leak tested: 1,600 units (unchanged)
  • Leak-test throughput rate: 2.4 units / min (unchanged)
  • Retest and handling allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base leak-test time = units or assemblies leak tested รท leak-test throughput rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 807 hr for required leak-test workload, the number this scenario is built around.
  • At this operating point the engine returns 667 hr for base leak-test time.
  • At this operating point the engine returns 21 % for retest and handling allowance.
  • At this operating point the engine returns 2.4 units / min for leak-test throughput rate.

How this compares with the baseline

  • Against the tool's baseline example, where retest and handling allowance sits at 18% and the headline result is 787 hr, this scenario comes in 2.54% above the baseline at 807 hr.
  • Use it for shift staffing, capacity planning, and deciding whether to add a second leak-test station before a volume ramp. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required leak-test workload: 807 hr (headline result)
  • Base leak-test time: 667 hr
  • Retest and handling allowance: 21 %
  • Leak-test throughput rate: 2.4 units / min

Run it with your numbers

  • Every input above is editable in the live Leak Test Workload Calculator calculator, which recalculates instantly and can be shared with the inputs intact.
