Parts Cleanliness Compliance at 71% target cleanliness pass rate: a worked example

This worked example runs the parts cleanliness compliance numbers for a tougher week than the baseline: 71% target cleanliness pass rate instead of the typical 98%. Calculate cleanliness compliance rate from passing samples, total tested samples, and target pass rate.

The inputs for this scenario

  • Cleanliness samples passing specification: 238 samples (held at the documented default)
  • Total cleanliness samples tested: 250 samples (held at the documented default)
  • Target cleanliness pass rate: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Parts cleanliness compliance rate = cleanliness samples passing specification ÷ total cleanliness samples tested × 100.
  • Parts cleanliness compliance rate works out to 95.2 % at these inputs, and this is the headline figure for the scenario.
  • Parts cleanliness compliance gap to target works out to -24.2 points at these inputs.
  • Cleanliness samples passing specification works out to 238 count at these inputs.
  • Total cleanliness samples tested works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target cleanliness pass rate sits at 98% and the headline result is 95.2 %, this scenario lands almost exactly on the baseline at 95.2 %.
  • Use it for periodic cleanliness reporting, PPAP and audit evidence, or to track whether a washer or chemistry change moved conformance. 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

  • Parts cleanliness compliance rate: 95.2 % (headline result)
  • Parts cleanliness compliance gap to target: -24.2 points
  • Cleanliness samples passing specification: 238 count
  • Total cleanliness samples tested: 250 count
