SATRA TM92 is intended to assess the resistance of completed footwear to repeated flexing. The method is applicable to all types of footwear.

Principle

The footwear sample is repeatedly bent through a specific angle of its natural bending line under the action of the testing machine. After a predetermined time or number of bends, a subjective assessment of shoe damage is performed. The number of bends or the time between evaluations, as well as the angle at which the shoe bends, are all determined by the type of shoe being tested.

Materials Testing System

Results Evaluation

1. Observe whether there are cracks in the soles, if any, measure the depth and length, and record them.
2. Observe whether there are cracks in the sole and upper.
3. Record the number of bending and bending angle.
