Label Verification Sample Size at 99% verification station uptime: a worked example

This scenario runs the label verification sample size calculation on the strong side: 99% verification station uptime, with every other input held at its documented default. Use it when label verification sample size in traceability, serialization and lot genealogy is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Labels verified per inspection cycle: 4 units / cycle (unchanged)
  • Available inspection cycles in the window: 480 cycles (unchanged)
  • Verification station uptime: 99 % (raised for this scenario; the documented default is 90)
  • Label first-pass verification yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross label verification sample size capacity = label verification sample size output per cycle × available label verification sample size cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good label verification sample size capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross label verification sample size capacity.
  • At this operating point the engine returns 19.2 units for label verification sample size downtime loss.
  • At this operating point the engine returns 57.02 units for label verification sample size yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where verification station uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when sizing a barcode verification or vision station, planning a sampling regime, or checking whether verification keeps pace with the packaging line. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good label verification sample size capacity: 1,844 units (headline result)
  • Gross label verification sample size capacity: 1,920 units
  • Label verification sample size downtime loss: 19.2 units
  • Label verification sample size yield loss: 57.02 units

Run it with your numbers

  • Every input above is editable in the live Label Verification Sample Size calculator, which recalculates instantly and can be shared with the inputs intact.
