ISO 132:2017规定了一种试验方法,用于比较在De Mattia型机器上反复弯曲时,硫化橡胶或热塑性橡胶对裂纹形成和扩展的阻力。为了确定裂纹扩展,在试件上进行人工切割,以开始切割扩展。
ISO 132:2017 specifies a method of test intended for use in comparing the resistance of vulcanized or thermoplastic rubbers to the formation and growth of cracks, when subjected to repeated flexing on the De Mattia type machine. For determination of crack growth, an artificial cut is made in the test piece to initiate cut growth.
