Does conditioning consume laboratory labor?

Unattended conditioning does not consume active person-hours. Include any attended checks in measured specimen labor, and schedule the elapsed waiting separately.

Where does fixture setup belong?

Enter total fixture setup and cleanup labor separately. Exclude those minutes from the per-specimen observation to avoid counting them twice.

Can repeat tests exceed the original specimen count?

Yes, when several repetitions are planned. Enter the additional tests explicitly instead of treating the count as a probability.

Does this calculate the compression-set result?

No. Measure initial and recovered specimen dimensions using the applicable approved test method. This calculator only plans the laboratory workload.

Compression Set Test Workload Calculator

Estimate the active labor needed for your compression-set test plan. Enter measured specimen handling, fixture work, explicit repeat tests, unattended waiting and available person-hours.

What this calculator does

Plan active compression-set laboratory labor from specimen handling, explicit retests and fixture work, while keeping unattended waiting separate.

Formula used

Total specimen tests = original specimens + repeat specimens
Specimen handling labor = total specimen tests × active minutes per specimen ÷ 60
Fixture labor = total fixture labor minutes ÷ 60; required labor = specimen handling labor + fixture labor
Available labor margin = available laboratory labor − required labor
Unattended waiting is reported separately and excluded from required labor

Inputs explained

Original Test Specimens: Original specimens listed on the compression-set test request.
Repeat Specimens: Additional specimen tests explicitly included in the retest plan.
Active Labor per Specimen: Observed preparation, loading, measuring and recording labor per specimen.
Total Fixture Labor: Separate setup and cleanup labor across all planned fixture sessions.
Unattended Conditioning and Recovery: Elapsed unattended waiting from the approved laboratory schedule.
Available Laboratory Labor: Person-hours allocated to this specimen and fixture workload.

How to use the result

Best suited to Compression-Set lab Staffing, explicit retest work plans.
Does not calculate compression-set performance, compliance, fixture capacity or calendar turnaround. Conditioning and recovery durations come from your approved method, not this example.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
