Tested Quality of Power Tools

Products have to meet the requirements of customers and application! We test and assess the quality of your hand-held tools and whether they meet the requirements. For this purpose, we have developed a conformity-declared testing process based on long-standing research at IPEK – the Institute of Production Engineering of Karlsruhe Institute of Technology (KIT). Testing is carried out by KIT Campus Transfer GmbH. Hand-held devices and tools having a good quality may be granted the quality label shown on the right by VPAZert (VPA Prüf- und Zertifizierungs GmbH).

Development of the Testing Method

The testing method serves to objectively assess the suitability of hand-held devices. Hand-held devices/power tools are understood to be electric tools (drilling machines, cordless screwdrivers, jigsaws, etc.) as well as gasoline-operated devices (such as chainsaws, brush cutters, etc.). The method is a result of research conducted under the direction of Professor Dr.-Ing. Sven Matthiesen at Karlsruhe Institute of Technology (KIT) and is based on established approaches to obtain independent assessments.

The Resulting Testing Process

The process is based on the method shown below and ensures independent, objective assessment of the suitability of hand-held devices. Detailed information on the testing method can be found in the download area on the right. The devices are always tested in comparison with reference devices that have already been found to have a high quality. Assessment of suitability is based among others on a technical construction analysis, determination of subjective impact criteria in the phases of purchase decision, commissioning and permanent use, check of the technical performance (wear studies, quality of the work result, durability tests), as well as on the assessment of use quality (measurement of productivity-affecting factors). After all defined tests have been passed successfully, the test label can be granted by VPAZert.

Test Label

The test label confirms the high suitability and quality of the hand-held device. The test label for tested quality is granted by VPAZert exclusively and only, if all test criteria of the test process above are met. The test label for tested quality shown on the right has a validity of one year.
