A statistical analysis for Key Comparisons with linear trend is proposed. The approach has the advantage that it is consistent with the case in which there is no trend. The uncertainties for KCRV and the degrees of equivalence are also provided. As an example, the approach is applied to Key Comparison CCEM-K2.
