Scope and common interpretation errors
For dimensional and assembly consistency, not choosing an arbitrary delay to make a failed result pass.
Recovery depends on temperature, load duration and geometry. Identical gauges cannot reconcile free-state data with measurements taken immediately after stretching.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Define starting conditions | Describe packaging restraint, unpacking, assembly and temperature. |
| 2 · Record a time series | Measure specimens from one batch at specified intervals to identify a repeatable window. |
| 3 · Document the method | Standardize handling, placement and timing, and repeat measurements on limit samples. |
A comparison to avoid misinterpretation
If inside diameter recovers after tight packaging is removed, use a validated conditioning procedure. Separately assess whether packaging caused permanent damage.

Frequently asked question
Can measurement be delayed until the size passes?
No. Agree the timing rule beforehand and apply it to every specimen.
