Abstract
NIST pressure calibration services with nitrogen are now based on two transfer standard piston gages for which the effective areas have been determined by calibration with the manometer developed at NIST for gas thermometry. Root-sum-squared three sigma uncertainties for the areas for the two gages are 3.05 ppm and 4.18 ppm.
摘要
美国国家标准与技术研究院（NIST）的氮气压力校准服务现基于两个传递标准活塞压力计，其有效面积已通过使用NIST为气体温度测量开发的压力计进行校准来确定。这两个压力计面积的根均方根三西格玛不确定度分别为3.05 ppm和4.18 ppm。
