From April to June 2018, a bilateral comparison of energy standards at 50/60 Hz was conducted, by both SIM and AFRIMET. The comparison included measurements of active energy at two frequencies and power factors of 1.0 and 0.5 lead/lag, aiming at the evaluation of the stated uncertainty and degrees of equivalence, between CENAMEP AIP (Panama) and NIS (Egypt).

This work presents the results of the SIM.EM-S14 supplementary comparison.
