Residual Contamination Analysis according to VDA 19.1
Technical cleanliness testing according to VDA 19.1 for parts, assemblies, and technical components.
What is VDA 19.1?
VDA 19.1 describes procedures for determining and evaluating particulate contamination on parts and assemblies.
The standard serves as the basis for ensuring technical cleanliness in the automotive, mechanical engineering, and industrial sectors.
Even in small amounts, particulate contamination can impair the function of sensitive components
and lead to increased wear, malfunctions, or failures.
