Does this predict bond strength?

No. It estimates test labor. Bond strength requires specimen dimensions, measured failure load and the applicable test procedure.

Where does the pull-test throughput come from?

Time representative specimens through loading, testing and unloading. Divide completed pulls by those active minutes.

Do conditioning hours belong in setup labor?

Only staffed handling belongs there. Unattended soaking, curing and chamber holds require separate elapsed-time planning.

How do I include repeat tests?

Enter the number of additional pulls you plan to run. Include only replacement specimens that will actually consume testing time.

Tensile Bond Load Test Time Calculator

Estimate the staffed hours needed for a tensile bond test campaign. Enter specimen counts, measured pull-test throughput, setup labor and available staffed hours.

What this calculator does

Plan staffed time for tensile bond testing, fixture setup and repeat pulls.

Formula used

First-pass labor (hr) = first-pass count ÷ rate ÷ 60
Additional labor (hr) = (repeat count ÷ rate + separate labor minutes) ÷ 60
Required labor = first-pass labor + additional labor
Hours balance = available labor − required labor

Inputs explained

Tensile Bond Specimens: Count from the lot traveler or test plan.
Pull-Test Throughput: Observed completed tasks per staffed minute.
Setup Labor: Active labor minutes from the work study.
Retest Specimens: Additional passes from the planned repeat-work list.
Available Labor: Staffed productive hours assigned to this lot.

How to use the result

Best suited to bond qualification coupon campaign, repeat pulls after invalid tests.
Unattended conditioning, curing and queue time are excluded. Separate campaigns are needed for different fixtures or test procedures.

Current U.S. benchmarks

The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 11,391 plastics and rubber products establishments employing about 815,988 workers (Census County Business Patterns, 2023).
