GOST 28653 Thermal Ageing Testing of Rubber Tracks and Tires
The GOST standard 28653:2014 specifies the methods for determining thermal ageing resistance of rubber tracks and tires. This testing is critical in ensuring that rubber components used in military vehicles meet the demanding performance criteria required by the sector.
In military applications, durability under extreme conditions is paramount. Rubber tracks and tires are subjected to high stress, temperature fluctuations, and harsh environmental conditions. GOST 28653 thermal ageing tests help manufacturers identify how well these materials will withstand prolonged exposure to elevated temperatures without degrading in performance or safety.
The testing procedure involves exposing rubber samples to a controlled environment where the temperature is gradually increased over time. This simulates real-world operational scenarios, providing insights into potential degradation of physical properties such as tensile strength and elongation at break. The test also evaluates changes in hardness, modulus, and other mechanical characteristics.
During this process, it's essential to prepare the rubber samples according to the standard specifications. This includes cutting specimens from the track or tire, ensuring they are free from defects, and conditioning them under specified humidity levels before testing. After exposure to heat, the samples undergo a series of mechanical tests to assess any changes in their properties.
Instrumentation plays a crucial role in accurately measuring the effects of thermal ageing on rubber materials. Key instruments include tensile testers for determining tensile strength and elongation, hardness testers for evaluating modulus changes, and viscometers or rheometers if viscosity is part of the evaluation criteria. Advanced testing facilities can also incorporate environmental chambers capable of simulating various temperature profiles.
The results from these tests are reported comprehensively in accordance with GOST 28653 requirements. Reports typically include detailed descriptions of the test setup, duration of exposure, observed changes in physical properties, and compliance or non-compliance with specified limits. Compliance officers and quality managers rely on such reports to ensure that rubber components meet not only current but also future performance expectations.
In summary, GOST 28653 thermal ageing testing is indispensable for the development and certification of rubber tracks and tires used in military vehicles. It ensures reliability under extreme conditions while contributing significantly to overall vehicle safety and operational effectiveness.

Why It Matters
The durability and reliability of rubber tracks and tires are critical for the performance of military vehicles. These components must endure harsh conditions, including extreme temperatures and high stresses, without compromising safety or functionality. GOST 28653 thermal ageing testing provides a standardized method to evaluate how these materials perform under such rigorous conditions.
By conducting this test, manufacturers can identify any potential weaknesses in the rubber composition before they become critical issues during field use. This early detection allows for improvements in material selection and processing techniques, enhancing overall product quality. Additionally, compliance with GOST 28653 ensures that products meet international standards, which is essential for export markets.
For R&D engineers working on new rubber formulations or design modifications, thermal ageing tests offer valuable data points to guide further development efforts. They can use the test results to refine their designs and materials choices, leading to more robust and efficient products.
The insights gained from these tests are also useful for quality managers overseeing production processes. By regularly assessing product performance through thermal ageing testing, they can ensure consistent quality across batches, reducing the risk of failures in critical applications.
Applied Standards
GOST 28653:2014 is specifically applied to rubber tracks and tires used in military vehicles. The standard outlines the procedures for determining thermal ageing resistance based on exposure to high temperatures over extended periods.
- Temperature Range: Tests are conducted at various temperature levels, typically starting from room temperature up to 80°C or higher, depending on the specific application.
- Duration of Exposure: Specimens are exposed to heat for durations ranging from several days to weeks, again dependent on intended use and environmental conditions.
The standard also specifies methods for preparing specimens, conditioning them before testing, and interpreting results. Compliance with GOST 28653 ensures that rubber components meet stringent quality benchmarks set by the Russian military and other international standards.
Environmental and Sustainability Contributions
- Material Efficiency: By ensuring that rubber components last longer under harsh conditions, GOST 28653 promotes efficient use of raw materials.
- Economic Benefits: Prolonged product life reduces the need for frequent replacements and associated costs.
The testing ensures that military vehicles remain operational for extended periods without costly repairs or replacements, contributing to overall economic sustainability. Additionally, by adhering to international standards like GOST 28653, manufacturers can demonstrate their commitment to environmental responsibility, which is increasingly important in global markets.
