Acceptance Test Labor at 7.2% troubleshoot and retest allowance: a worked example

Suppose troubleshoot and retest allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate acceptance test labor for rugged electronics ATP, functional test, EMI/EMC checks, thermal checks, and customer sell-off.

The inputs for this scenario

  • Acceptance test procedure steps: 120 test steps (held at the documented default)
  • ATP completion pace: 12 test steps / hr (held at the documented default)
  • Troubleshoot and retest allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base acceptance test hours = acceptance test steps รท ATP completion pace.
  • Required acceptance test hours works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base acceptance test hours works out to 10 hr at these inputs.
  • Troubleshoot and retest allowance works out to 7.2 % at these inputs.
  • ATP completion pace works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where troubleshoot and retest allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It converts the number of ATP steps and the realistic step-per-hour pace into base test hours, then inflates them by a troubleshoot-and-retest allowance to give required acceptance test hours. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required acceptance test hours: 10.72 hr (headline result)
  • Base acceptance test hours: 10 hr
  • Troubleshoot and retest allowance: 7.2 %
  • ATP completion pace: 12 pieces / min
