Sterilization & Sterile Barrier Manufacturing worked example

Sterile Barrier Seal Strength at 7.2% aql sampling share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop aql sampling share to 7.2%, then walk the calculation through step by step. Estimate sterile-barrier seal-strength testing cost from pouch sample count, per-test cost, AQL sampling share, and sealer validation setup.

The inputs for this scenario

  • Pouches Seal-Tested: 120 pouches (held at the documented default)
  • Cost per Seal Test: 18 $/pouch (held at the documented default)
  • AQL Sampling Share: 7.2 % (the input this scenario stresses; the baseline uses 10)
  • Seal Validation Setup: 1,800 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total seal-strength cost = pouches tested x cost per seal test x AQL sampling share + seal validation setup.
  • Total sterile barrier seal strength cost works out to 1,956 $ at these inputs, and this is the headline figure for the scenario.
  • Sterile barrier seal strength cost per unit works out to 16.3 $ / piece at these inputs.
  • Variable sterile barrier seal strength cost works out to 156 $ at these inputs.
  • Fixed sterile barrier seal strength adder works out to 1,800 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where aql sampling share sits at 10% and the headline result is 2,016 $, this scenario comes in 3% below the baseline at 1,956 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to aql sampling share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It models testing spend only — it does not size a statistically valid AQL plan or account for destructive-test scrap value or retest costs on failures.
