GB/T 45644-2025 "Thermal plasticity plastic inspection wells anti-ground and traffic load performance test method" is an important technical standard in the field of municipal engineering in our country. The standard is approved by the State Administration for Market Regulation, and will be officially implemented on November 1, 2025 by the National Technical Committee for Standardization of Plastic Products and the Urban Water Supply and Drainage Standardization Technical Committee. The standard systematically specifies the performance test methods of thermal plasticity plastic inspection wells under ground loads and traffic dynamic loads, including test environment control, sample prepative specifications, static/dynamic loading procedures, and deformation evaluation and other key technical requirements. By simulating the test of mechanical properties under actual working conditions, it provides a scientific basis for the quality control and security evaluation of plastic inspection wells in municipal engineering.
