Proficiency Test 2013

Proficiency Test 2013

KRÜSS Customer Support Lab certified with success

At the recent Proficiency Test 2013 on thermoplastics, rubber and films our KRÜSS Customer Support Lab earned excellent reviews at the determination of the surface energy by measuring the contact angle.
290 laboratories from 40 countries participated for 100 different methods. For determining the surface energy, 13 different labs analysed two different plastics with three different test liquids. More than one half of the testing institutes used a KRÜSS instrument to measure the contact angle.

The executed procedure was arranged with equivalent samples which were sent to the laboratories, where they were analysed according to previously defined parameters. The results were sent to the Kunststoff-Institut Lüdenscheid (polymer institute) for evaluation afterwards.

The participation in the annual Proficiency Test evaluates if the measuring methods are valid and if the results of tests/analyses are comparable to those obtained in other laboratories. The Proficiency Test is an important instrument for the external quality control and documentation of the performance of laboratories.
