01Freeze sample identity
Assign each unit an ID and record model, shape, nominal dimensions, weight, color, printing, scent claim if any, material or formulation reference, supplier batch and package revision. Photograph every side before handling. Do not group samples only because they share a character or retail name.
02Condition and measure the baseline
Store comparison units together for a defined time and record temperature and humidity where practical. Measure dimensions and weight with named tools and precision. Describe surface feel and visible condition before compression so an existing mark is not attributed to the test.
03Define the compression cycle
Specify how the sample is compressed, approximate force or fixture setting, target deformation, hold time, release method, cycle count and rest intervals. Use the same orientation for comparable shapes. If testing by hand, name the limitation and avoid claiming laboratory precision.
04Record recovery at fixed times
Photograph or measure the sample immediately after release and at predetermined intervals. Record time to reach the defined recovery condition and any permanent set, twisting or localized collapse. Compare like-for-like units rather than assigning fast or slow without a reference.
05Inspect surfaces, seams and decoration
After the planned cycles, inspect for cracks, tears, pinholes, opened seams, peeling print, coating separation, tackiness, color transfer and residue. Record location and severity with close photographs. Stop and quarantine units showing unexpected damage pending technical review.
06Handle odor observations carefully
Use a small panel and consistent unpacking interval if odor is part of buyer acceptance. Record descriptors and intensity scale, not conclusions about toxicity or chemical identity. Ventilation, packaging time and individual sensitivity can influence perception; laboratory analysis is a separate activity.
07Link findings to evidence and changes
Compare results with the approved sample, product brief and packaging method. Record whether material, colorant, coating, printing, mold, curing, supplier or packing changed. Send relevant questions through change control and confirm required market testing for the exact production configuration.
