UV Curing worked example
UV Cure Validation Sample Size at 99% inspection efficiency: a worked example
Push inspection efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it during PPAP, IQ/OQ/PQ, or routine production-validation planning to pick a defensible sample size for cure verification.
The inputs for this scenario
- Production volume per shift: 2,400 parts / shift (unchanged)
- Sampling rate: 5 samples / 1,000 (unchanged)
- Inspection efficiency: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Raw samples = production volume × sampling rate ÷ 1,000) to the inputs above produces each figure below.
- At this operating point the engine returns 13 samples per validation for recommended sample pull, the number this scenario is built around.
- At this operating point the engine returns 12 samples for raw samples.
- At this operating point the engine returns 99 % for inspection efficiency.
How this compares with the baseline
- Against the tool's baseline example, where inspection efficiency sits at 90% and the headline result is 14 samples per validation, this scenario comes in 7.14% below the baseline at 13 samples per validation.
- It converts your production volume and target sampling rate into a raw sample count, then inflates it by inspection efficiency to give the number of parts to actually pull. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
