TECHNICAL STANDARD
ASTM D714-25
Standard Test Method for Evaluating Degree of Blistering of Paints
ASTM International
2025
Current
WHAT DOES THIS STANDARD COVER?
Provides a photographic blistering-rating approach that supports consistent coating-condition records.
WHY IS IT RELEVANT?
Helps communicate observed blistering consistently, while a rating alone does not establish cause or project acceptability.
KEY INSPECTION CONSIDERATIONS
Record the observed location, extent and surrounding coating condition alongside the rating.
WHAT THE STANDARD SHOULD NOT BE USED TO ASSUME
A blistering rating is not a stand-alone failure diagnosis or acceptance decision.
PRACTICAL INSPECTION APPLICATION
Use as a repeatable visual descriptor within condition records and maintenance planning.
RELATED TECHNICAL STANDARDS
