Calibration Lab & Gauge Management worked example

Calibration Failure Rate at 99% maximum acceptable failure rate: a worked example

Push maximum acceptable failure rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when calibration failure rate in calibration lab and gauge management needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Failed or out-of-tolerance calibrations: 8 calibrations (unchanged)
  • Total calibrations completed: 250 calibrations (unchanged)
  • Maximum acceptable failure rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Calibration failure rate = failed or out-of-tolerance calibrations ÷ total calibrations completed × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for calibration failure rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for failure-rate headroom to limit.
  • At this operating point the engine returns 8 count for failed or out-of-tolerance calibrations.
  • At this operating point the engine returns 250 count for total calibrations completed.

How this compares with the baseline

  • Against the tool's baseline example, where maximum acceptable failure rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the percentage of calibrations that failed or came back out of tolerance and the headroom in points to your maximum acceptable failure rate. 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.

Results at a glance

  • Calibration failure rate: 3.2 % (headline result)
  • Failure-rate headroom to limit: 95.8 points
  • Failed or out-of-tolerance calibrations: 8 count
  • Total calibrations completed: 250 count
