The results of the inter-RMO key comparison EURAMET.L-K5.2016 on the calibration of a step gauge are reported. Twenty-two National Metrology Institutes from four different metrological regions all over the world participated in this comparison which lasted three years, from December 2015 to December 2018. Two artefacts were circulated so that the varying ranges of participants equipment could be accommodated. A 1020 mm ceramic monolithic step gauge remained stable throughout the comparison. A 610 mm steel step gauge changed length, possibly due to an impact while travelling between participants. The comparison of this artefact was divided into two groups, those before the damage and those after, with the reference value for each group derived from a linking participant who had demonstrated equivalence in the 1020 mm artefact circulation. For the 1020 mm comparison the inverse-variance weighted mean was taken as reference value. Of the twenty two participants, eleve...

一维CMM工件的校准：量规（EURAMET.L-K5.2016）

报告了关于RMO钥匙间比较EURAMET.L-K5.2016的校准步骤。来自全球四个不同计量区域的22个国家计量学院参加了为期三年的比较，从2015年12月到2018年12月。分发了两个文物，以便可以容纳不同范围的参与者设备。在整个比较过程中，一个1020 mm的陶瓷整体式台阶仪保持稳定。610毫米的钢制台阶仪改变了长度，这可能是由于参与者之间旅行时受到的冲击。将该假象的比较分为损伤之前和之后的两组，每组的参考值来自已在1020 mm假象循环中表现出等效性的链接参与者。对于1020 mm的比较，将反方差加权平均值作为参考值。在二十二位参与者中，精灵...
