GB/T 46230-2025 in English

This standard specifies the methods for evaluating the viscoelastic properties of solution-polymerized styrene-butadiene rubber. It covers the determination of key parameters such as storage modulus, loss modulus, and damping factor under various temperature and frequency conditions. The procedures described in this standard are applicable for testing the viscoelastic behavior of rubber materials used in a wide range of industrial applications. The standard provides detailed instructions on sample preparation, testing conditions, and data analysis. It is designed to ensure consistency and reliability in the evaluation process, facilitating the comparison of results across different laboratories and testing environments. The methods outlined are intended for use by researchers, manufacturers, and quality control personnel involved in the production and application of solution-polymerized styrene-butadiene rubber.
