Industrial Cleaning, Washing & Parts Cleanliness calculator

Parts Cleanliness Compliance Calculator

Use this calculator to measure parts cleanliness compliance for production lots, validation batches, or customer release checks. It fits particle count limits, residue limits, visual cleanliness criteria, and pass or fail cleanliness inspections.

What this calculator does

  • Calculate cleanliness compliance rate from passing samples, total tested samples, and target pass rate.
  • Use it when quality teams need to track whether washed parts meet particle, residue, or customer cleanliness specifications.
  • The result shows pass rate and the point gap to the cleanliness target.

Formula used

  • Parts cleanliness compliance rate = cleanliness samples passing specification ÷ total cleanliness samples tested × 100
  • Parts cleanliness compliance gap to target = parts cleanliness compliance rate - target cleanliness pass rate

Inputs explained

  • Cleanliness samples passing specification: Count samples or lots that passed the applicable particle, residue, visual, or customer cleanliness requirement.
  • Total cleanliness samples tested: Use the matching total number of parts, lots, filters, or residue tests inspected for the same period.
  • Target cleanliness pass rate: Enter the required pass rate from the control plan, customer specification, quality KPI, or internal release target.

How to use the result

  • Use it to monitor washer performance, validate process changes, trigger containment, and decide whether rewash or root cause work is needed.
  • It depends on representative sampling and does not show which contaminant type caused failures.

Common questions

  • What is the parts cleanliness compliance calculator for? It calculates the share of tested parts or lots that passed the cleanliness specification.
  • What information should I enter? Use passing sample count, total tested sample count, and target pass rate.
  • What does the result tell me? The result helps quality teams decide whether cleaning performance is acceptable or needs corrective action.
  • When is the result only an estimate? It is only an estimate when sampling is limited, inspection methods vary, or cleanliness limits differ by part family.
