Scope and common interpretation errors
For ordinary mass-change tests, not drinking-water or food-contact compliance.
Wiping force and waiting time create systematic differences. Thin and porous parts retain liquid differently; unequal geometry can make percentage comparisons misleading.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Standardize preparation | Define cleaning, liquid removal and weighing order; do not mix wiped and drip-dried specimens. |
| 2 · Keep separate time points | Record initial mass, mass after removal and mass after an agreed recovery period. |
| 3 · Review geometry and repeatability | Use matched shapes or report differences, and check the balance and handling repeatability. |
A comparison to avoid misinterpretation
If mass drops substantially after several minutes, investigate residual liquid and evaporation before concluding long-term absorption.
Frequently asked question
Does returning to initial mass prove full recovery?
Dimensions and the target function still need checking.
