ISO 37

Test Materials: ISO 37 specifies the use of rubber specimens in various forms, typically in the shape of dumbbells or sheets. The materials should be representative of the final product, free from defects, and prepared according to the standards outlined in the document to ensure consistency and accuracy in testing.

Test Process: The testing process involves subjecting the rubber specimens to a uniaxial tensile test using a tensile testing machine. The samples are elongated at a constant rate until they break, with the test parameters, such as temperature and humidity, controlled to reflect real-world conditions. Proper calibration of the equipment is critical to obtaining valid results.

Test Result Interpretation: Results from ISO 37 testing are interpreted by analyzing the stress-strain curve generated during the test. Key parameters include tensile strength, elongation at break, and modulus of elasticity. These values are essential for assessing the material’s performance characteristics, such as flexibility and durability, ensuring they meet the required specifications for their intended application.
