日前,江苏省计量院真空标准漏孔检定装置新建高标顺利通过计量标准考核,获得计量标准考核证书。真空标准漏孔检定装置的测量范围为(10-9~10-7)Pa?m3/s,不确定度为Urel=12%(k=2),可以开展同范围、不确定度为Urel=15%(k=2)的标准漏孔的检定校准工作。目前华东地区除了上海计量院,尚无其他计量技术机构有这一技术能力开展相应的 Recently, the Jiangsu Provincial Institute of Metrology vacuum leak detection device built a new high standard passed the measurement standard assessment, access to measurement standards examination certificate. Vacuum standard leak detection device measuring range (10-9 ~ 10-7) Pa? M3 / s, the uncertainty of Urel = 12% (k = 2), can carry out the same range, the uncertainty of Urel = 15% (k = 2) standard leak calibration verification work. At present, in addition to Shanghai Institute of Metrology in East China, there is no other measurement technology institutions have the technical capacity to carry out the corresponding
