Abstract:

An apparatus for measuring the tear strength of an elastomer specimen having a housing which contains therein a specimen holder, a controllable heat source, a force applying assembly which includes a taut wire, means for measuring the amount of movement of the force applying assembly and a temperature programmer and strip chart recorder. The force applying assembly by means of the taut wire applies a predetermined amount of force on the elastomer specimen which has been precut on one side thereof. The load on the taut wire is counterbalanced by a calibrated spring such that the load decreases linearly to zero as the tearing of the specimen is completed. Author
