TECHNICAL STANDARD
ASTM D610-25
Standard Practice for Evaluating Degree of Rusting on Painted Steel Surfaces
ASTM International
2025
Current
WHAT DOES THIS STANDARD COVER?
Provides a visual rusting-rating approach that supports consistent survey records and maintenance planning.
WHY IS IT RELEVANT?
Helps describe observed rusting consistently, while a rating alone does not establish structural condition or the cause of deterioration.
KEY INSPECTION CONSIDERATIONS
Record the observed area and context so visual ratings can be interpreted with other survey evidence.
WHAT THE STANDARD SHOULD NOT BE USED TO ASSUME
A rusting rating is not, by itself, a diagnosis of coating failure or asset condition.
PRACTICAL INSPECTION APPLICATION
Use as a consistent visual descriptor within condition-survey records and maintenance planning.
