Round robin tests

Round robin tests or inter-laboratory comparison tests (ILCs) in chemical analysis are an important means of quality control. Laboratories accredited in accordance with EN ISO 17025 are required to participate in such studies on a regular basis. The successful participation in ILCs is a prerequisite for accreditation or the continued validity thereof.
In such tests, an individual laboratory can compare its own results from the analysis of a particular sample with the results of a group of other laboratories and thus obtain information about the performance of their own methods.


The IAG round robin test is an international laboratory performance test which is conducted once a year and includes two samples.
