Many Thanks. Your proficiency testing team

Over the past 25 years, the Kunststoff-Institut Lüdenscheid has earned an international reputation as one of the leading institutions in the field of plastics. With more than 15 years of experience in organising interlaboratory tests, we are also one of the established providers in this field. One thing is certain: the combination of our expertise in plastics and proficiency tests is unique on the market. You will also benefit from this. In order to demonstrate our quality level, the desired accreditation according to DIN ISO/IEC 17043 is only a logical consequence.


Due to the strong growth and an advanced internationalization of our activities in the area of interlaboratory tests, the proficiency tests of the Kunststoff-Institut Lüdenscheid will in future be offered under the brand name “Deutsches Institut für Ringversuche”.


You can view our complete offer in the menu item “Portfolio” or in our catalogue, which is also an interactive registration form. After registration you will receive a non-binding offer with comprehensive price information.


Further information about our institute and general explanations on the EQASs are presented under the menu item “Our proficiency tests”.


Measure us by our own claim to offer you the best round robin tests in the plastics sector.
