Material Assay Workload at 22% preparation and retest allowance: a worked example

This worked example runs the material assay workload numbers for a tougher week than the baseline: 22% preparation and retest allowance instead of the typical 30%. Estimate lab or quality hours needed for battery material assays from sample count, testing rate, and preparation allowance.

The inputs for this scenario

  • Battery material assay samples: 96 samples (held at the documented default)
  • Assay testing rate: 8 samples / hr (held at the documented default)
  • Preparation 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 assay testing time = assay sample count รท assay testing rate.
  • Required assay workload works out to 14.64 hr at these inputs, and this is the headline figure for the scenario.
  • Base assay testing time works out to 12 hr at these inputs.
  • Preparation and retest allowance works out to 22 % at these inputs.
  • Assay testing rate works out to 8 samples / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where preparation and retest allowance sits at 30% and the headline result is 15.6 hr, this scenario comes in 6.15% below the baseline at 14.64 hr.
  • Use it when staffing the assay bench, quoting lot-release turnaround, or sizing lab capacity against incoming sample volume. 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 assay workload: 14.64 hr (headline result)
  • Base assay testing time: 12 hr
  • Preparation and retest allowance: 22 %
  • Assay testing rate: 8 samples / hr
