Will this determine a fire rating?

No. Fire performance requires the applicable physical tests and qualified interpretation. This calculator only adds the active labor in your laboratory plan.

Does the conditioning time increase required labor?

No. Unattended conditioning is elapsed waiting, not active person-hours. Include attended observations in the measured specimen work.

How are repeat specimens charged?

Each repeat adds the same measured specimen labor as an original specimen. Repeat documentation is included in the reporting input for its submission.

Can I combine different test methods?

Use a separate calculation when specimen labor or reporting differs between methods. Sum the resulting person-hours in your staffing plan.

Fire Test Laboratory Workload Calculator

Plan laboratory staffing for a defined fire-test submission workload. Enter submission and specimen counts, measured active work, explicit repeat specimens and unattended conditioning time.

What this calculator does

Estimate active specimen and reporting labor for fire-test submissions without treating unattended conditioning as staffing time.

Formula used

Total specimens = submissions × specimens per submission + additional repeat specimens
Specimen labor = total specimens × active minutes per specimen ÷ 60
Reporting labor = submissions × reporting minutes per submission ÷ 60; required labor = specimen labor + reporting labor
Repeat labor subtotal = additional repeat specimens × active minutes per specimen ÷ 60
Unattended conditioning is reported separately and excluded from required labor

Inputs explained

Planned Submissions: Distinct test submissions in the approved laboratory work order.
Specimens per Submission: Original specimens specified for each submission by your test plan.
Active Labor per Specimen: Measured preparation, attended testing and cleanup labor per specimen.
Reporting Labor per Submission: Observed documentation labor including repeat-test records for each submission.
Additional Repeat Specimens: Extra specimen tests listed explicitly in the laboratory work order.
Unattended Conditioning Time: Elapsed unattended conditioning from the approved specimen preparation schedule.

How to use the result

Best suited to Fire-Test submission Staffing, repeat specimen work orders.
Does not calculate a fire rating, compliance, acceptance, laboratory accreditation or test outcome. Does not schedule chamber occupancy, shared equipment, unattended conditioning or calendar turnaround.

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.
