Welcome to the website of the German Institute for Interlaboratory Comparisons (Deutsches Institut für Ringversuche), the department for proficiency testing and reference materials of the Kunststoff-Institut Lüdenscheid. Over the past 30 years, the Kunststoff-Institut Lüdenscheid has earned an international reputation as one of the leading institutions in the field of plastics and currently has about 100 employees. With more than 15 years of experience in the field of proficiency testing, we are one of the pioneers in the field of interlaboratory comparisons for plastics.
Our proficiency testing program and our reference materials cover a wide range of tests and analyses. The focus is on different plastic materials, plastic products and plastics processing. A wide range of proficiency testing, from the “classics” of mechanical and thermal testing methods to “exotic” methods such as generative processes or the investigation of the compostability of plastics, are part of our portfolio. You can view our complete offer in our catalogue, which is also an interactive registration form. After registration you will first receive a non-binding offer with comprehensive price information. As a clear distinctive feature of our international activities in the field of interlaboratory comparisons, the Kunststoff-Institut Lüdenscheid offers proficiency tests under the brand name “Deutsches Institut für Ringversuche”.
