Which paint tests belong in the package?

Include the specified routine tests, such as viscosity, density or fineness of grind. Use observed labor for your actual methods and preparation requirements.

Should drying time count as labor?

Count only attended work. Unattended drying or conditioning affects release timing but does not consume continuous hands-on labor.

Can I divide the result by two analysts?

That estimates elapsed time only if work splits evenly and equipment and dependencies allow parallel execution. The calculator reports person-hours, not a detailed schedule.

Where do preparation and documentation times come from?

Measure the actual sample preparation, cleanup, recording and review tasks. Keep those minutes separate from the hands-on testing interval to avoid double counting.

Paint, Resin & Polymer Compounding calculator

Batch Sample Workload Calculator

Estimate hands-on laboratory workload for a defined coating test package. Enter sample count, observed testing, preparation and documentation minutes plus the staffed hours available for that queue.

What this calculator does

Plan staffed laboratory hours for a defined paint or resin sample queue using measured hands-on work.

Formula used

Required labor hours = samples × (testing + preparation + documentation minutes per sample) ÷ 60
Testing labor hours = samples × testing minutes per sample ÷ 60
Preparation and documentation hours = samples × (preparation + documentation minutes per sample) ÷ 60
Labor capacity margin = available laboratory labor hours − required labor hours

Inputs explained

Batch Samples to Test: Whole samples queued for the same routine test package.
Hands-On Testing Time: Measured person-minutes for the specified tests on one sample.
Sample Preparation Time: Measured person-minutes preparing and cleaning up one sample.
Sample Documentation Time: Measured person-minutes recording and reviewing one sample result.
Available Laboratory Labor: Staffed person-hours allocated to this sample queue.

How to use the result

Best suited to routine paint sample Queues, laboratory staffing plans.
Unattended drying, conditioning and instrument waiting are excluded. Workload does not predict elapsed release time or validate a sampling plan.

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.
Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
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 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
