Scope and common interpretation errors
For aging-validation matrices; supplier instructions and customer specifications remain applicable.
Moisture can affect interfaces, inserts and nearby materials. Compound coupons alone may miss bonded or electrical assembly boundaries.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Define actual exposure | Separate dry hot air, humid air, condensation and direct water contact. |
| 2 · Create matched groups | Use comparable specimens from the same batch for dry and damp heat, retaining unaged controls. |
| 3 · Check complete-part function | Record assembly, sealing and interface changes as well as appearance and hardness. |
A comparison to avoid misinterpretation
If rubber remains intact after dry heat but an insert interface fails after damp heat, investigate the interface instead of attributing everything to inadequate silicone heat resistance.
Frequently asked question
Can damp heat replace dry heat because it is harsher?
Not necessarily. Choose according to failure mechanisms and the agreed test plan.
