Standard requirements for high and low temperature tensile testing of rubber and plastic materials

Rubber and plastic materials are widely used in automotive, cable, sealing, new materials, and other fields. Their tensile properties under high and low temperature environments are core indicators for evaluating product weather resistance and structural stability. Industry testing must strictly adhere to national and international standards to ensure that test data is accurate and compliant, and can be used for quality inspection, acceptance, and scientific research reference.

The execution standards for high and low temperature tensile testing of rubber and plastic materials are differentiated based on the material type: plastic materials are tested according to the GB/T 1040 series of standards, while rubber elastomers follow the GB/T 528 standard. Additionally, they are compatible with international testing specifications such as ISO and ASTM, meeting the testing and acceptance requirements of different industries.

The testing environment and sample specifications are stringent. The conventional testing temperature range covers -60℃ to 200℃, which can be customized and adjusted according to the actual working conditions of the product. Standard dumbbell-shaped samples are uniformly used. Before high and low temperature testing, sufficient pre-cooling/pre-heating is required to ensure the overall temperature uniformity of the sample and eliminate data deviations caused by temperature differences. The tensile speed for conventional testing is set at 50mm/min, maintaining a constant and uniform loading speed throughout the process.

The core testing indicators for testing include tensile strength, elongation at break, stress-strain properties, etc. In scientific research and precision testing scenarios, the temperature control accuracy of the equipment needs to be ≤±0.5℃, and the mechanical testing accuracy should meet the standards to fulfill high-precision testing requirements.

The Fule high and low temperature tensile testing machine adopts an integrated design, eliminating the need for separate equipment. It is highly adaptable to various high and low temperature tensile tests for rubber and plastic materials, precisely meeting national standard testing requirements. With stable data and the ability to customize temperature zones and testing procedures, it is suitable for use in factory quality inspection, university research, and third-party testing institutions across all scenarios.
