At the meeting in September 2010, the EUROMET TC Length decided to carry out a comparison of laser distance measuring instruments (EDMs), with the Central Office of Measures (GUM), Poland as the pilot laboratory. The results of this international comparison will support the Calibration and Measurement Capabilities (CMCs) declared by the NMIs in the CIPM Mutual Recognition Arrangement (MRA). Four EDMs of different quality classes had been used as artifacts (three of them were provided by BEV). The measurements were carried out over a distance up to 30, 40 or 50 m, depending on measurement capabilities of participants. 2 Organisation Conditions for participation The participating laboratories were NMIs required to fulfil the following conditions: • signatory (or applicant) of the CIPM MRA; • calibrating EDMs for their customers as a regular service; • being well trained in handling EDMs; • being capable of measuring at least within a 20 m range.
