SATRA TM60 determines the resistance of shoe soles and other flexible materials to flex cracking.

The test method involves subjecting a test specimen to repeated flexing at a constant speed and under controlled conditions until a crack or cut is observed. The test specimen can be of various shapes, such as a rectangle or trapezium, clamped at one end while the other is moved back and forth in a reciprocating motion.

The SATRA TM60 test method specifies the number of flex cycles, the frequency of flexing, and the criteria for evaluating the degree of cracking or cut growth. The standard also provides guidelines for specimen preparation, test equipment, and data analysis. SATRA TM60 is widely used in the footwear and leather industry to evaluate the durability and performance of shoe soles and other flexible materials.

NextGen’s Ross Flex Tester complies with SATRA TM60 standard.
