Compression Set Test Workload at 22% conditioning, fixture, and retest allowance: a worked example

This worked example runs the compression set test workload numbers for a tougher week than the baseline: 22% conditioning, fixture, and retest allowance instead of the typical 30%. Estimate lab hours required to prepare, condition, compress, measure, and document foam compression set specimens.

The inputs for this scenario

  • Compression set specimens to test: 72 specimens (held at the documented default)
  • Specimens processed per hour: 9 specimens / hr (held at the documented default)
  • Conditioning, fixture, and retest allowance: 22 % (the input this scenario stresses; the baseline uses 30)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base compression set test workload time = compression set specimens to test รท specimens processed per hour.
  • Required compression set test workload time works out to 9.76 hr at these inputs, and this is the headline figure for the scenario.
  • Base compression set test workload time works out to 8 hr at these inputs.
  • Conditioning, fixture, and retest allowance works out to 22 % at these inputs.
  • Specimens processed per hour works out to 9 specimens / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where conditioning, fixture, and retest allowance sits at 30% and the headline result is 10.4 hr, this scenario comes in 6.15% below the baseline at 9.76 hr.
  • Use it when scheduling a compression set test batch, quoting a certification lead time to a customer, or checking whether your lab capacity covers the week's open work orders. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required compression set test workload time: 9.76 hr (headline result)
  • Base compression set test workload time: 8 hr
  • Conditioning, fixture, and retest allowance: 22 %
  • Specimens processed per hour: 9 specimens / hr

Run it with your numbers
