How to Perform ISO 37 Rubber, vulcanized or thermoplastic – Determination of tensile stress-strain properties

Home / Testing Standards / ISO 37 Rubber, vulcanized or thermoplastic – Determination of tensile stress-strain properties

Summary of Test

ISO 37 covers the testing of tensile properties of vulcanized and thermoplastic rubbers. The specification describes testing the stress-strain properties of either dumb-bell or ring specimens in a tensile testing machine until rupture.

Prior to conducting ISO 37, it is important to read the entire specification in the relevant ISO publication.

Testing Procedure

  1. Prepare specimens as described in the standard.
  2. Load the sample into a pair of tensile grips and attach your extensometer (if available).
  3. Begin the test by separating the tensile grips at a rate specified in the standard and run until sample break (rupture).

Calculations:

  • Tensile Strength
  • Elongation at Break
  • Stress at a Given Elongation
  • Elongation at a Given Stress
  • Stress at Yield
