Abstract
The CCAUV.A-K3 Key Comparison has involved 15 countries organized in two loops with two
common laboratories, CENAM and DPLA. The measurements took place in 2003. This is the first CCAUV key
comparison organized with more than one loop, and therefore the analysis of the results required a more
elaborated method to arrive to the desired degrees of equivalence per laboratory and between any pair of
laboratories. An implementation of the linear least squares has been applied to the analysis of the CCAUV.AK3
key comparison. In this paper, the mathematical development is presented in parallel with the results of
the comparison. The details of the analysis are reviewed, and suggestions are made in order to further
improve comparison protocols in acoustics.
