Parts Cleanliness Compliance at 99% target cleanliness pass rate: a worked example
What does the result look like when target cleanliness pass rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when quality teams need to track whether washed parts meet particle, residue, or customer cleanliness specifications.
The inputs for this scenario
- Cleanliness samples passing specification: 238 samples (unchanged)
- Total cleanliness samples tested: 250 samples (unchanged)
- Target cleanliness pass rate: 99 % (raised for this scenario; the documented default is 98)
Working through the calculation
- Applying the documented formula (Parts cleanliness compliance rate = cleanliness samples passing specification ÷ total cleanliness samples tested × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 95.2 % for parts cleanliness compliance rate, the number this scenario is built around.
- At this operating point the engine returns 3.8 points for parts cleanliness compliance gap to target.
- At this operating point the engine returns 238 count for cleanliness samples passing specification.
- At this operating point the engine returns 250 count for total cleanliness samples tested.
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 %.
- A figure at this level is achievable when target cleanliness pass rate is genuinely sustained, not just peaked for a shift. It treats every sample equally and as pass/fail; it does not weight by severity of the cleanliness miss or by particle size distribution, which two parts at the same pass rate can differ on sharply.
Results at a glance
- Parts cleanliness compliance rate: 95.2 % (headline result)
- Parts cleanliness compliance gap to target: 3.8 points
- Cleanliness samples passing specification: 238 count
- Total cleanliness samples tested: 250 count
