| Content | Problem In round-robin tests for internal verification of measurement procedures, the test institutes in- volved were provided by a neutral body with a set of samples which were as identical as possible. The results of round-robin tests are frequently the only means by which participating bodies can document the quality of their own work to third parties. They are an essential element of the ex- ternal quality assurance of test institutes and labo- ratories. In the round-robin tests for in-plant test bodies conducted by the IFA during the last twenty years or so, the participating bodies were supplied with prepared samples for analysis. Round-robin tests of this kind lack an important element of hazard- ous substance measurement, namely that of sam- pling. In order to include this element, a new test gas device at the Institute Work and Health of the German Social Accident Insurance (IAG) in Dres- den was installed which delivered a homogeneous test gas simultaneously to up to fifteen partici- pants. The participants take samples from this test gas device themselves before analysing them in their own laboratories. In 2005 this test gas device was transferred to the IFA’s laboratories. Activities The round-robin tests involving sampling have been conducted since 2002. The tests also form part of the quality management system within the Measurement system for exposure assessment Test gas stream for the performance of round-robin tests including sampling at the IFA of the German Social Accident Insurance Institu- tions – MGU, and are used intensively by their laboratories. Numerous company test depart- ments, accredited test institutes, the German regional OH&S authorities, and laboratories else- where in Europe also take part in the round-robin tests. To date, round-robin tests have been performed on the test gas stream on various solvents, inor- ganic gases and vapours, direct-reading instru- ments and volatile organic compounds (VOC). In 2009 a round-robin test on aldehydes was added. Further information on the round-robin tests can be found on the IFA s web site.
