VDA 19.1 testing
Technical cleanliness testing according to VDA 19.1 for parts, assemblies and technical components in a DAkkS-accredited laboratory. Send the part or drawing, agree the scope, receive the test report.
Service
VDA 19.1 describes methods for determining and assessing particulate contamination on functionally relevant automotive components. It is the basis for securing technical cleanliness in automotive, mechanical engineering and industry.

Even small amounts of particulate contamination can impair the function of sensitive components and lead to increased wear, malfunctions or failures.
Typical reasons for testing are short-notice questions, ongoing series projects, complaints and the qualification of new parts and processes. For new parts and extraction methods, a decay measurement is recommended first.
