A sorting process for used friction elements such as friction discs is provided, including determining whether the friction elements are heat compromised based at least in part on a wave scattering property of at least one frictionally interactive face of each of the used friction elements. Suitable friction elements may be sorted into an acceptable category, and unsuitable friction elements sorted into a scrap category. A method of assembling a machine system such as a transmission includes determining suitability of a friction element for service therein by measuring a wave scattering property such as reflectivity of at least one frictionally interactive face of the friction element, and coupling the friction element with the same or a different machine system for returning to service therein based at least in part on the determination of suitability.
