日前,从国际计量局(BIPM)等效互认数据库获悉,中国计量科学研究院(以下简称“中国计量院”)电磁领域获国际互认的校准和测量能力(CMC)从144项增长到182项,用于表示CMC测量不确定度水平的矩阵数量从68个增长到81个,综合排名从2015年的第8位跃升至世界第3,标志着我国电磁领域校准和测量能力有了新的提高,在该领域的计量科技水平已跻身世界前列。CMC是国际计量界为实现各国校准测量数据全球等效一致而采用的一种重要评价形式,其数量和水平是
Recently, the International Bureau of Weights and Measures (BIPM) Database for Mutual Recognition of Equivalence was informed that the CMC has achieved 144 increases in the internationally recognized calibration and measurement capabilities (CMC) of the electromagnetic field of China Institute of Metrology (hereinafter referred to as “China Metrology Institute” To 182 items. The number of matrices used to represent the CMC measurement uncertainty increased from 68 to 81, and the overall rankings jumped from 8th in 2015 to 3rd in the world, marking the country’s ability to calibrate and measure the electromagnetic field New improvements in the field of metrology and technology has been among the highest in the world. CMC is an important form of evaluation used by the international metrology community to achieve global equivalence of measured data from all countries. Its quantity and level are
