The General Administration of Market Regulation recently issued 65 national measurement technical specifications, covering more than 20 professional fields such as radio, ionizing radiation, medicine, biology, and digital metrology. The release of this batch of national measurement technology standards will strongly support quality improvement and technological progress in related industries, and further guarantee people's livelihood safety and market order. In terms of food safety, the newly formulated “Cooking Oil Quality Tester Calibration Specification” provides a uniform measurement and calibration basis for rapid testing equipment for edible oil quality. This specification applies to edible oil quality detectors used in scenarios such as rapid on-site inspection, manufacturer quality control, and supermarket self-inspection. Standardized instrument calibration methods ensure accurate and reliable test data, help detect poor quality oil and expired oil in a timely manner, and protect the “safety on the tip of the tongue” of ordinary people. In the field of ionizing radiation, the “X-ray Safety Checker Calibration Specification” published in this revision is widely used in the measurement and calibration of security inspection equipment in public places. The specification uniformly stipulates how to calibrate key parameters such as image resolution, penetrating power, and radiation dose of X-ray safety inspection instruments to ensure that security equipment accurately identifies prohibited items while effectively controlling the radiation dose within a safe range.
