In this paper we contrast two approaches for proving the validity of relaxation limits α → ∞ of systems of balance laws ut + f(u)x = αg(u) In one approach this is proven under some suitable stability condition; in the other approach, one adds artificial viscosity to the system ut + f(u)x = αg(u) + ∈uxx and lets α → ∞ and ∈ → 0 together with Ma ≤ e for a suitable large constant M. We illustrate the usefulness of this latter approach by proving the convergence of a relaxation limit for a system of mixed type, where a subcharacteristic condition is not available.
