ISO 132:2017

Rubber, vulcanized or thermoplastic — Determination of flex cracking and crack growth (De Mattia)

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.
