  • Interlaboratory studies as a tool for many purposes : Proficiency testing, learning exercises, quality control and certification of matrix materials


Interlaboratory studies are collaborative exercises to assess or improve the quality of their measurements. They are an important aspect of quality control and quality assurance systems which should be set up by all testing laboratories. They are efficient tools to investigate the method and the laboratory performance and also to certify reference materials. They can be applied with a research or teaching objective but they can also be used to assess the performance of a normalised method or the ability of a laboratory to perform a given task. As such they are complementary to accreditation audits.
