Astm D61821 Pdf Jun 2026

ASTM D6182-21 establishes a standardized, Bally flexometer-based method for evaluating the flexibility and adhesion of surface coatings on finished leather, specifically detecting cracking, delamination, and discoloration. The test simulates real-world stress on materials for applications like footwear and upholstery, ensuring quality control by simulating continuous flexing.
