近日，中国市场监管总局批准新建11项国家计量基准，涵盖声学、电离辐射、流量等多个关键领域。这些基准作为国家最高测量标准，是统一全国量值的核心依据，对科技创新、产业发展和国际贸易具有深远意义。新增基准包括超声功率、听力零级、辐射波长等测量标准，精准度达到国际先进水平。例如，在医疗领域，超声功率基准可提升诊断设备准确性；在核能应用中，电离辐射基准能保障安全监测可靠性。此外，流量基准将助力能源计量和环境保护，支撑碳足迹监测等绿色发展需求。此次扩容体现了中国在计量科学领域的持续突破，不仅强化了国家质量基础设施，也为高端制造、医疗卫生等行业提供了技术支撑，进一步推动中国标准与国际体系接轨。
Recently, China’s State Administration for Market Regulation approved the establishment of 11 new national measurement standards, covering key areas such as acoustics, ionizing radiation, and flow measurement. As the highest reference for measurement in the country, these standards serve as the core basis for unifying national metrological values, with significant implications for technological innovation, industrial development, and international trade.The new standards include benchmarks for ultrasonic power, auditory zero-level, and radiation wavelength, achieving precision levels comparable to international advanced standards. For instance, in healthcare, the ultrasonic power standard enhances the accuracy of diagnostic equipment; in nuclear applications, ionizing radiation standards ensure the reliability of safety monitoring. Additionally, flow measurement standards will support energy metering and environmental protection, facilitating green development initiatives such as carbon footprint monitoring.This expansion reflects China’s continuous breakthroughs in metrology, strengthening the national quality infrastructure while providing technical support for high-end manufacturing, medical care, and other industries. It further promotes the alignment of Chinese standards with international systems.
