During the World Games 2025 in Chengdu, Sichuan province, SAMR organized and guided the Sichuan Administration for Market Regulation, National Institute of Metrology, National Institute of Measurement and Testing Technology, and other relevant institutions to carry out the action on precision measurement, to support the great event.
Technological R&D and application, the innovation of standard materials, and the capacity building of measurement standard instruments provided guarantees for the safe and stable operation as well as the fair competition of the Games.
Cutting-edge metrology technologies provide robust technical support. SAMR urged metrology institutions to develop new technologies of energy and time-frequency measurement to ensure the safe and stable operation of the combustion system of the torch named “Zhumeng”, which means “chasing dreams”. Also, the application of time-frequency metrology in intelligent navigation robotic dogs enabled precise positioning, optimal route planning, and obstacle avoidance. These advanced metrology technologies safeguarded the operation of numerous smart devices during the Games, including intelligent transportation systems, unmanned security routing and inspection vehicles, and pool-cleaning robots.
Standard materials provide critical basis for ensuring fairness and integrity. SAMR emphasized the timely supply of high-purity ß-receptor agonist standard materials. By adopting internationally recognized metrological calibration procedures, a breakthrough was achieved in detection sensitivity to the level of one part per billion, ensuring the results were comparable, traceable, and arbitrable.
Standard measuring instruments have played a key role in guaranteeing the smooth and efficient operation of the Games. The stable operation of the events relied on the resilient support of metrological infrastructure. A comprehensive inspection was carried out at 17 core venues and surrounding areas in Chengdu. Through calibrating environmental monitoring equipment such as temperature and humidity sensors, anemometers, and PM2.5 monitors, real-time traceability of microclimate parameters at the venues was realized.
