This standard specifies the test method for evaluating the room-temperature flex resistance of finished footwear and outsoles. The method involves mounting the finished shoe or outsole on a flex testing machine and subjecting it to repeated bending at a specified angle and frequency. The test aims to measure the crack length and delamination length of the outsole and sidewall after a predetermined number of flex cycles, while also observing any changes in the upper. This standard is not applicable to footwear with excessively high heels, overly thick soles, or excessive rigidity. Implementation of this standard requires specialized testing instruments designed according to its methodology, specifically flex testing machines.
