Pressure Test Throughput at 61% test bench availability: a worked example

This worked example runs the pressure test throughput numbers for a tougher week than the baseline: 61% test bench availability instead of the typical 85%. Calculate effective pressure test bench throughput per shift by combining valves per test cycle, available cycles per shift, bench availability, and first-pass test yield.

The inputs for this scenario

  • Valves tested per cycle: 2 valves / cycle (held at the documented default)
  • Test cycles available per shift: 24 cycles / shift (held at the documented default)
  • Test bench availability: 61 % (the input this scenario stresses; the baseline uses 85)
  • First-pass test yield: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross throughput = valves per cycle x cycles per shift.
  • Effective valves tested per shift (passed) works out to 27.82 valves at these inputs, and this is the headline figure for the scenario.
  • Gross valve test throughput per shift works out to 48 valves at these inputs.
  • Valves lost to bench downtime works out to 18.72 valves at these inputs.
  • Valves lost to first-test failures works out to 1.46 valves at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where test bench availability sits at 85% and the headline result is 38.76 valves, this scenario comes in 28.24% below the baseline at 27.82 valves.
  • Use it to size test-bench capacity against production output, justify a second bench, or model how a yield or uptime improvement changes daily passed-valve count. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Effective valves tested per shift (passed): 27.82 valves (headline result)
  • Gross valve test throughput per shift: 48 valves
  • Valves lost to bench downtime: 18.72 valves
  • Valves lost to first-test failures: 1.46 valves
