Rankings are based on the results of each lab in coming closest to the mean (average) values for all laboratories participating in the Round Trial on all six measurements. The range of scores for the combined properties among the 72 instruments was 0.22 to 1.65 (a score of zero would be perfect), and the median overall evaluation of combined properties was 0.51.
The results in CSITC RT 2008-1 are consistent with the results from the Round Trials conducted in 2007. The average difference between the evaluation grades of identical instruments in comparison between the four Round Trials conducted during 2007 was 0.1, which means, that the evaluation of each single testing facility, and therefore its accuracy, is stable.
