Residual dirt analysis of precision parts and particle determination of filters

Residual dirt from production processes remaining on surfaces impairs the function of electronic or technical components. For manufacturers, suppliers, parts cleaners or users of corresponding components in the automotive industry, DEKRA offers accredited cleanliness tests according to customer specifications and international standards.

Technical cleanliness influences component quality

Particularly in the automotive industry, as well as in medical technology, aviation and the electrical industry, expectations regarding the quality and functionality of components are high. It is therefore important to avoid any possible contamination in production and processing operations. For example, silicones, solvents and other critical substances can cause coating defects in the painting process or damage to components due to contamination.
