Of these, $^{52}$Co and $^{52}$Co$^m$ have been experimentally determined for the first time and found to be more bound than predicted by extrapolations. The isobaric multiplet mass equation for the $T=2$ quintet at $A=52$ has been studied employing the new mass values. No significant breakdown (beyond the $3\\sigma$ level) of the quadratic form of the IMME was observed ($\\chi^2/n=2.4$). The cubic coefficient was 6.0(32) keV ($\\chi^2/n=1.1$).
