Powder Fill Accuracy Audit Calculator at 1% target maximum fill exception rate: a worked example

Suppose target maximum fill exception rate falls to 1%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the audit rate for fill checks outside approved limits using inspected count, sample size, and target exception rate.

The inputs for this scenario

  • Powder fill checks outside approved limit: 5 checks (held at the documented default)
  • Total powder fill checks inspected: 1,000 checks (held at the documented default)
  • Target maximum fill exception rate: 1 % (the input this scenario stresses; the baseline uses 0.75)

Working through the calculation

  • The calculation starts from the formula this tool documents: Actual fill-check exception rate = fill checks outside approved limit ÷ total fill checks inspected × 100.
  • Actual fill-check exception rate works out to 0.5 % exceptions at these inputs, and this is the headline figure for the scenario.
  • Fill exception gap to target works out to 0.5 points at these inputs.
  • Fill checks outside approved limit works out to 5 checks at these inputs.
  • Total fill checks inspected works out to 1,000 checks at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum fill exception rate sits at 0.75% and the headline result is 0.5 % exceptions, this scenario lands almost exactly on the baseline at 0.5 % exceptions.
  • It computes the percentage of powder charge-weight checks that fell outside the approved limit and the gap between that rate and your target maximum exception rate. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Actual fill-check exception rate: 0.5 % exceptions (headline result)
  • Fill exception gap to target: 0.5 points
  • Fill checks outside approved limit: 5 checks
  • Total fill checks inspected: 1,000 checks
