Comparison of 10 V DC reference standards.
The comparison started in October 1998. On 31 December 2000, the standards were measured by all participants. During the first months of 2001 the last measurements were performed on the travelling standard at NMi-VSL. All measurement data and uncertainty budgets from the participants were transformed in the same format to make the calculation and comparison of the results easier. In September 2001 the Draft A report was finished and sent to the participants for comments. A few laboratories sent some valuable comments, which will be taken into account in the Draft B report. Therefore, the calculations of the results have to be slightly changed. The changes will be introduced in the first months of 2002. We expect the Draft B report to be finished by June 2002.
There has been a delay in the processing of the comments to the Draft A report due to the change of coordinator of this project. As a result, the completion date will be later than expected previously
Final Report 2003-04-30
The comparison has been completed and results are available in the KCDB.
The comparison started in October 1998. In January 2001, the last measurements of the pilot laboratory were completed. In September 2001 the Draft A report was finished and sent to the participants for comments. In March 2002 the revised version of the Draft A report was sent to the participants. In June 2002, the third version of the Draft A was completed. All participants agreed on this version of the report, so it was transformed in a Draft B report. This Draft B report was submitted to the support group of this comparison. In the mean time, a proposal was made for linking this EUROMET comparison to the corresponding CCEM comparison.
After including some minor changes as proposed by the support group, the report and the linking documents were submitted to the EUROMET technical chairman for electricity.
The report has been sent to the BIPM to include the results in the key comparison database.
