The report summarizes the Consultative Committee for Mass (CCM) key comparison CCM.P-K4.2012 for absolute pressure spanning the range of 1 Pa to 10 000 Pa. The comparison was carried out at six National Metrology Institutes (NMIs), including National Institute of Standards and Technology (NIST), Physikalisch-Technische Bundesanstalt (PTB), Czech Metrology Institute (CMI), National Metrology Institute of Japan (NMIJ), Centro Nacional de Metrología (CENAM), and DI Mendeleyev Institute for Metrology (VNIIM). The comparison was made via a calibrated transfer standard measured at each of the NMIs facilities using their laboratory standard during the period May 2012 to September 2013. The transfer package constructed for this comparison preformed as designed and provided a stable artifact to compare laboratory standards. Overall the participants were found to be statistically equivalent to the key comparison reference value.

CCM.P-K4.2012 绝对压力从 1 Pa 到 10 kPa 关键比较的最终报告

该报告总结了质量咨询委员会 (CCM) 的关键比较 CCM.P-K4.2012 对跨越 1 Pa 至 10 000 Pa 范围的绝对压力。比较是在六个国家计量机构 (NMI) 进行的，包括国家标准与技术研究所 (NIST)、联邦物理技术研究所 (PTB)、捷克计量研究所 (CMI)、日本国家计量研究所 (NMIJ)、国家计量中心 (CENAM) 和 DI Mendeleyev 计量研究所 (VNIIM) . 比较是通过在 2012 年 5 月至 2013 年 9 月期间使用其实验室标准在每个 NMI 设施测量的校准转移标准进行的。为此比较构建的转移包按设计进行，并提供了一个稳定的工件来比较实验室标准。
