GB/T 31402 - 2023 is used to determine the surface antibacterial activity of non-porous materials such as plastics. The standard specifies the preparation method of the sample required for the test to ensure that it can represent the true characteristics of the material. Clarify the technical requirements of the test equipment, and strictly describe the antibacterial activity test process, including the type, concentration, time of action of the inoculated bacteria, and the subsequent detection and calculation method of the survival number of bacteria. According to this standard, the antibacterial ability of the surface of the material can be accurately evaluated, providing a scientific basis for the development of antibacterial materials, product quality control and related industry applications, and helping to improve product hygiene and safety.
