Understanding the ASTM 4 Point System for Fabric Quality Inspection

Explore how the ASTM 4 point system assesses fabric quality through a standardized defect scoring method.

40 views

The ASTM 4 point system is a fabric inspection method used to assess the quality of textile products. Points are assigned to defects based on their size and severity: 1 point for defects 3 inches or smaller, 2 points for defects 3-6 inches, 3 points for defects 6-9 inches, and 4 points for defects over 9 inches. A total score of 40 points or fewer per 100 square yards is considered acceptable quality.
