Abstract APMP attenuation key comparison, APMP.EM.RF-K19.CL linked the comparison results to the corresponding CCEM comparison. The calculation method of weighted mean was used in the calculation of the linking correction. The method of median of absolute deviation was used for identifying statistical outlier from the linking data. It was considered whether measurement results in CCEM comparison of the linking laboratories were validity as well. The linking results show that the calculation result of linking correction is reliable and the evaluation of the uncertainties is reasonable.
