ASTM D412-16 (2021) "Standard Test Method for Vulcanized Rubber and Thermal plasticity resilience tensile" is designed to evaluate the performance of materials under tensile conditions. This standard applies to vulcanized thermoset rubber and thermal plasticity resilience, through different test methods (such as dumbbell-shaped and cut ring samples), the measurement of their tensile performance. Although tensile performance can provide the basic characteristics of the material, the performance requirements in practical applications may be more extensive. Therefore, the comparison of different materials should be carried out under the same test conditions. Temperature, Humidity, specimen shape and other factors have an important influence on the test results and need to be strictly controlled to ensure comparability and accuracy. The application of this standard helps to develop and evaluate the engineering design and product specifications of materials under tensile loading, and is an important basis for material selection and quality control in the industry.
