GB/T 15047-2025 "Test Method for Torsional Rigidity of Plastics" specifies a test method for determining the torsional rigidity of plastics (especially thermoplastics) within a specified temperature range by measuring the apparent rigidity modulus. This standard details the test principle, which involves applying torque to a specimen at a set temperature and measuring its torsional angle. It also provides unified specifications for test equipment, specimen preparation, conditioning, test procedures, and result calculation. The core testing instrument required for implementing this method is a torsion testing machine (or torsional tester), which must be capable of applying controlled torque to the specimen and measuring the corresponding torsional angle. This standard is a comprehensive revision of the 1994 edition and aims to provide more precise and standardized technical guidelines for evaluating the mechanical properties of plastic materials.
