Retesting is sometimes needed within a product lifecycle. Let's look at 5 common situations that can trigger retesting.
1. Changes in Raw Materials
Any change in formulation, supplier, or material grade may require retesting to confirm performance remains consistent.
2. Manufacturing or Process Modifications
Adjustments to equipment, curing times, temperatures, or production methods can affect test outcomes.
3. Revisions to ASTM Standards
ASTM standards are periodically updated. Retesting ensures compliance with the latest requirements.
4. New Product Applications
Products used in new environments or markets may require additional validation.
5. Quality or Performance Concerns
Customer complaints, failures, or inconsistencies often trigger retesting to identify root causes.

FAQ: ASTM Retesting Requirements
Does ASTM specify retesting intervals?
Some standards do, while others rely on material or process changes to trigger retesting.
Is retesting required after minor changes?
Even small changes can impact performance. A lab can help determine if retesting is necessary.
Can old test data still be used?
Only if materials, processes, and standards remain unchanged.
