Let G be a strongly regular graph with three distinct eigenvalues and A his matrix of adjacency. In this work we associate a three dimensional real Euclidean Jordan algebra V with rank three to A and next we consider a Jordan frame B of idempotents of V. Next we analyse the spectra of a particular convergent Hadamard series of A2 and establish asymptotic inequalities over the spectra and the parameters of G.
