Foam, Insulation & Cushioning Products calculator

Compression Set Test Workload Calculator

Estimate lab hours required to prepare, condition, compress, measure, and document foam compression set specimens. Use it for polyurethane, polyethylene, EVA, cushioning, gasket, mattress, or automotive interior foam lots that need compression set or related compression-performance testing.

What this calculator does

  • Estimate lab hours required to prepare, condition, compress, measure, and document foam compression set specimens.
  • Use it for polyurethane, polyethylene, EVA, cushioning, gasket, mattress, or automotive interior foam lots that need compression set or related compression-performance testing.
  • Plans quality-lab workload for compression set testing on flexible, semi-rigid, molded, or converted foam products.

Formula used

  • Base compression set test workload time = compression set specimens to test ÷ specimens processed per hour
  • Required compression set test workload time = base compression set test workload time × allowance factor

Inputs explained

  • Compression set specimens to test: Enter specimens, lots, or sample pieces that require measurement, compression, conditioning, recovery, and final reading.
  • Specimens processed per hour: Use observed lab throughput including specimen prep, thickness measurement, fixture loading, unloading, and data entry.
  • Conditioning, fixture, and retest allowance: Add allowance for conditioning time coordination, retests, fixture cleaning, customer paperwork, or out-of-spec investigations.

How to use the result

  • Use it for lab scheduling, release timing, staffing, and deciding whether customer samples or production lots will delay shipment.
  • It assumes released test plans, prepared specimens, available fixtures, calibrated equipment, normal conditioning time, and no unusual retest, certification, material hold, or customer engineering review.

Common questions

  • What information do I need before using the Compression Set Test Workload? Use specimen count, lab throughput in specimens per hour, and allowance for conditioning, fixture handling, documentation, and retesting.
  • What does the result mean? It estimates required hours after applying the entered allowance for setup, conditioning, fixture loading, test observation, documentation, or retesting.
  • When is the result only an estimate? It is an estimate when foam density, sheet thickness, cell structure, board dimensions, nest efficiency, cut tolerance, adhesive coverage, cure conditions, compression behavior, scrap handling, QC sampling, or production mix differs from the assumptions entered.
  • What decision can I make from the result? Use required hours to schedule fixtures, prioritize lots, add lab support, or adjust promised release dates.
