Seven parameters that the rubber tensile strength testing machine needs to obtain

1) The maximum force value (tensile strength) that occurs when the sample is stretched to fracture;

2) The force value (breaking strength) of the specimen when it breaks;

3) The force value corresponding to the yield point (tensile stress at the yield point);

4) The force value (constant elongation stress) when the sample is stretched to a given elongation;

5) The elongation of the electronic stretching machine when the sample is stretched to a given stress (constant stress elongation);

6) The elongation corresponding to the yield point (yield point elongation);

7) The elongation (elongation at break) of the specimen at break.
