Interlaboratory studies (sometimes referred to as collaborative studies, or round robins) are investigations in which measurements are made on one or several materials at several laboratories. These studies are typically conducted for one of three reasons: (i) to evaluate a measurement method; (ii) to evaluate a reference material; or (iii) to evaluate the proficiency of the laboratories themselves.
